Bellow Safety Valve Manufacturer in USA

Bellow Safety Valve Manufacturer in USA

SVR Global is a known bellow safety valve manufacturer in USA, With compliance to API, ASME, and ISO certifications. Safety and reliability are two cornerstones of industrial operations. When it comes to protecting pipelines, boilers, and pressurized systems from dangerous overpressure, bellow safety valves play an essential role. Their unique design ensures precise pressure relief while neutralizing the effects of back pressure and minimizing leakage.

What is a Bellow Safety Valve?

A bellow safety valve is a type of pressure relief valve equipped with a metallic bellows that isolates the spring and bonnet from back pressure. This design ensures consistent set pressure and prevents leakage, even under fluctuating operating conditions.

Unlike conventional safety valves, the bellow design provides extra protection against corrosion, increases valve life, and offers greater reliability in severe service environments.

Advantages of Bellow Safety Valves

Back Pressure Compensation – Bellows ensure accurate set pressure despite varying back pressures.

Leak-Tight Performance – Enhanced sealing minimizes fugitive emissions.

Corrosion Resistance – Protects spring and internal components from aggressive media.

Extended Service Life – Reduces wear and fatigue for longer operational performance.

Versatile Applications – Suitable for gas, steam, liquid, and chemical services.

Safety Compliance – Designed as per API 520, ASME Sec VIII, and ISO 4126.

Low Maintenance – Simple design allows easy inspection and replacement.

Parts of a Bellow Safety Valve

Valve Body – Cast steel, stainless steel, or alloy steel for durability.

Bellows – Corrosion-resistant stainless steel or Inconel.

Disc & Seat – Precision machined for leak-tight shut-off.

Spring – Calibrated to exact set pressures.

Bonnet – Protects spring and internal components.

Inlet & Outlet Connections – Flanged, threaded, or welded options.

Lever/Actuator – Manual or automatic release mechanisms.

Types of Bellow Safety Valves -

Conventional Bellow Safety Valve – Standard relief design for low to medium back pressure.

Balanced Bellow Safety Valve – Designed to handle higher back pressure conditions.

Pilot-Operated Bellow Safety Valve – Provides precise control and stable operation in critical applications.

High-Temperature Bellow Safety Valve – For steam and boiler applications in power plants.

Cryogenic Bellow Safety Valve – Engineered for LNG and ultra-low temperature systems.

Industries Using Bellow Safety Valves in USA

Oil & Gas – Protecting wellheads, refineries, and gas distribution systems.

Power Generation – Boilers, turbines, and steam networks.

Petrochemical & Chemical – Corrosive and high-pressure media handling.

Water Treatment & Desalination – Pressure protection in pumping stations.

Marine & Offshore – LNG storage and shipboard systems.

Butterfly Valve Manufacturers in Canada

Butterfly Valve Manufacturers in Canada

SVR Global, one of the top-rated butterfly valve manufacturers in Canada, proudly supplies precision-engineered valves for critical projects across North America. With a focus on quality, compliance, and customization, we deliver butterfly valve solutions designed for long-term durability and performance. In a world where industrial operations demand cost-effective, compact, and high-capacity flow control systems, butterfly valves have emerged as one of the most trusted choices. Their simple quarter-turn design, low-pressure drop, and minimal space requirements make them ideal for a wide range of applications—from municipal water systems in Ontario to chemical process plants in Alberta.

Why Choose Butterfly Valves?

Butterfly valves are rotary motion valves with a disk-type closure mechanism that rotates to open or close the flow path. They are lightweight, quick to operate, and highly versatile—offering excellent value for both on-off and throttling duties.

Key Advantages:

Compact design and lightweight construction

Low-pressure drop across the valve

Quick quarter-turn actuation

Lower cost than ball or gate valves

Suitable for large-diameter piping systems

Industries We Serve in Canada and the USA

Water and Wastewater Treatment – Filtration, distribution, and stormwater systems

Power Generation – Cooling water and condensate lines in thermal and hydro plants

Oil & Gas – Low-pressure pipeline isolation and tank farm applications

HVAC and District Energy Systems – Chilled and hot water loops

Chemical and Petrochemical Plants – Corrosive media and process control

Pulp & Paper – Slurry handling and effluent processing

Mining and Slurry Transport – Abrasive media and chemical dosing

Types of Butterfly Valves –
