Our designs are specifically made to provide the highest standards in the entire production process, a high degree of dependability, sustainability and durability.

Definition of a Globe Valve:

A globe valve gets its name from the shape of its body. An internal baffle divides the body of a globe valve's two parts. It consists of a stem that swings up and down to control fluid flow and a disc (ball or composition or plug) attached to it. The flow line is either parallel to or inclined in the direction of the seats. By sliding the disc against the flow stream, it ceases the flow of fluid.

Since a globe valve is bi-directional, fluid can flow through it in either direction. It can be utilized automatically or manually.

The most frequent application of a globe valve is to open, close, or throttle flow in systems.

Types of a Globe Valve:

API Globe Valve

The two sides of a globe valve are unscrewed to open and close the valve. It is most commonly used in systems to open, close, or throttle flow. A globe valve has a stem that swings up and down to control flow, as well as a disc (ball, composition, or plug) and a seat that are both linked to the valve body. The flow line is either parallel to or inclined towards the seats. A globe valve is bi-directional, meaning the fluid can flow in either direction within the valve. It allows you to control the flow and pressure as well as full cut off the flow. It can be used both manually as well as automatically.

Bellow Seal Globe Valve

A Bellow Seal Globe Valve is a control valve with a compact structure that uses bellow to seal the valve stem components. The bellow valve has a bellow within, and the stainless-steel bellows' lower end is welded to the stem to keep the system fluid from eroding it. To produce a permanent seal, the other end is positioned between the body of the valve and the cover of the valve. This double seal construction prevents leakage, as the stem packaging will prevent additional leakage even if the bellows collapse. The bellows are welded to the valve stem to guarantee consistent working efficiency and to avoid valve stem vibration caused by valve insert movement.

Forged Steel Globe Valve

Forged steel is a material created by fusing iron and carbon under extreme pressure. Forged steel has lower surface porosity, a finer grain structure, stronger tensile and fatigue strength, and more ductility than other treated steels. Steel becomes ductile and malleable when heated to forging temperature, allowing it to be shaped into the required shape with force and pressure.

Forged valves are created using a process known as forging, which involves shaping metals & alloys while they are still solid. Forged valves are known for their strength, making them excellent for high-pressure and high-temperature applications.

What is Forging?

Forging is a manufacturing process involving the shaping of metal through hammering, pressing, or rolling. These compressive forces are delivered with a hammer or die. Forging is often categorized according to the temperature at which it is performed- cold, warm or hot forging. A wide range of metals can be forged.

What is Forged Steel?

Forged steel is created by alloying iron and carbon under great pressure.   Forged steel has lower surface porosity, a finer grain structure, stronger tensile and fatigue strength, and more ductility than other treated steels. When steel is heated to forging temperature, it becomes ductile and malleable, allowing it to be molded into the required shape with force and pressure. Using our processing methods and steel forging, we can shape a permanent steel item without it cracking.

What is a Check Valve?

A check valve is a mechanical device that allows liquids and gases to flow exclusively in one direction and prevents flow reversal. It's a one-way directional valve, which means it has two openings in the body, one for fluid to enter and one for fluid to exit. Backflow forces the valve to close, whereas fluid flow in the desired direction opens it. The mechanics of a check valve are simple, and they function automatically to prevent fluid from flowing in the wrong direction.

Applications of Check Valves:

Virtually every plumbing or fluid transfer application imaginable, be it industrial, commercial, or domestic, employs check valves. Check valves are often utilized for one of four reasons in a number of applications because of how they work:

To prevent backflow damage to downstream equipment

To avoid contamination as a result of reverse flow

To avoid siphoning

To maintain a vacuum seal

Advantages of Check Valves:

Backflow prevention

Capability to withstanding both high and low pressures

Can be utilized horizontally and vertically

Internal components cannot be examined.

Occasionally, discs become caught in the open position.

Slamming discs are noisy

Hammering with water

Problems with reverse flow

Tapping & Chattering

Disc banging in the open position, resulting in damage and wear. 

Cannot be operated with fluid containing solid particles as they may accumulate between the seat and disc and stop the disc from closing.

Ball Valve Manufacturer in USA

Being a valuable ball valve manufacturer in USA, SVR Global offers a wide range of product solutions, satisfying even the most demanding operating conditions, ensuring more flexibility, more capacity and therefore more excellent economy.

What is a Ball Valve?

A ball valve is a quarter-turn on/off valve with a rotational motion that controls the flow of a liquid or gas. 

Ball valves are referred to as quarter-turn valves because the ball rotates 90 degrees between the fully open and fully closed positions. On/off valves either allow flow (on) or obstruct it completely (off). These valves are also known as isolation valves, because they can effectively shut down flow into a segment of a system, often for maintenance to be performed. 

A ball valve comprises a valve housing, which is often a metal casting and a perforated ball. The flow is restricted by turning the ball 90 degrees around its axis using a stem. 

Advantages of Ball Valves:

Compact in size

Corrosive environments aren’t an issue

Do not require lubrication

Easy to use

Fast-acting

Flexibility in design

Inexpensive

Long life expectancy

Low-pressure drop (flow is almost unrestricted) 

Reduced chances of leakage

Requires little maintenance

Suitable for emergency power outages

Suitable for use in high-pressure environments

Disadvantages of Ball Valves:

Body cavity filled with fluid

Not suitable for high temperature

Not suitable for throttling

The partially exposed seat erodes quickly in a throttling position due to the impact of high-velocity flow.

Should be positioned upright and cannot be used for throttling because the valve handle has been rotated.

Industries that use Ball Valves:

Automotive

Chemical

Cryogenic

Oil & Gas

Petrochemical

Power Processing

Vacuum 

Water Treatment

Types of Ball Valves:

Floating ball valve

A floating ball valve features a ball, a valve, and a stem. The stem is connected to a slot at the top of the ball which allows the ball to rotate a quarter turn (90 degrees). The ball is free to float inside the valve body. The ball is held in the position by the compression of the two elastomeric seats against the ball. 

Once pressure is applied, the flow will push the ball against the seat creating a bubble-tight seal. This type of valve design is capable of bi-directional shut-off. The floating valve is very difficult to operate when upstream pressure is high. 

In a house, a float valve is installed in a water storage tank and flush tanks, so that water flow is stopped automatically once the tank is filled up with water.

Forged steel ball valve

A forged steel ball valve is a common type of valve used to control and regulate fluid flow. As the name suggests, it is a ball valve made out of forged steel.

A ball valve is opened and closed by rotating the lever handle clockwise and counterclockwise, respectively. When the ball hole is parallel to the fluid flow, the valve is said to be open, and when the ball hole is rotated at 90 degrees, the valve is said to be closed.

Trunnion ball valve

A short shaft like an extension called Trunnion is set in the body. The trunnion-mounted ball valve design features a trunnion anchoring at the top and bottom of the ball. The ball is supported by two floating or spring-loaded seats that remain in constant contact with the ball. Regardless of the pressure, this design guarantees a positive seal on both downstream and upstream seats.

Check Valve Manufacturer in USA

SVR Global is a prominent check valve manufacturer in USA with a vast choice of Check Valves to choose from. Our Check Valves are put through rigorous testing to ensure that they meet all of our clients' needs. We also provide customized Check Valves to meet unique industrial requirements.

What is a Check Valve?

Check valves are classed as self-actuated, straight-line valves. An interesting feature of these valves is the possibility to set the valve opening with a specific pressure value, to ensure that the fluid reaches users, with a certain pressure value.

A check valve is a mechanical device that allows only unidirectional fluid flow. They are called 'One-way valves', 'Clack valves' or 'Non-return valves' since they only allow media to flow in one direction.

They have two media ports, one inlet and one output. Usually check valves are formed by a shutter, a spring and a gasket.

The operating principle is very simple: as soon as the fluid pumped into the pipe reaches a pressure value that overcomes the force of the spring, the shutter will open, and it will let the fluid flow through. The higher the fluid pressure, the bigger the shutter opening will be. When the pressure value falls below the value that counteracts the force of the spring, the shutter closes, preventing any backflow.

Industries that use Check Valves:

Check valves are used in sewage, water treatment, medical, chemical processing, power generation, hydropower, petrochemical, and food, and beverage processing industries for effective backflow prevention. Offshore and onshore oil and gas production, gas plants, LNG, liquid gases, refineries, petrochemical, chemical, fertilizer, terminals, pipelines, power, desalination, water, and other industries all employ check valves.

Types of Check Valves-

Dual Plate Check Valve

Also known as Silent Check Valve, a Dual Plate Check Valve is an automatic mechanical non-return valve, which opens with a forward flow and shut to a reversal inflow. It consists of 2 discs attached to the valve body by a pin and operated by the action of springs, which immediately start closing the valve when the fluid stops.

Forged steel check valve

Forging steel check valves are compact, sturdy, and ideal for high-pressure and high-temperature applications. These are non-return valves that only operate in one direction. The body is built of forged steel and is available in two-port configurations: full and standard. A forged steel lid sits atop the body. 

Swing Check Valve

Swing check valves use a swinging disc on a hinge to regulate the flow of a liquid, gas, or solid stream in one direction while preventing backflow from contaminating the source fluid. In other words, like all check valves, the swing valve is a non-return valve.

Swing check valves are the most common type of large check valve, and a typical example is a toilet flushing valve that rises and lowers. Swing valves normally require some type of physical motion to activate them, therefore manual twisting of the handle is a common subject. In some internal pipe systems, however, a spring check valve is integrated with the swing valve to eliminate the need for human intervention.
