Check Valve Manufacturer in USA
SVR Global is a renowned check valve manufacturer in USA, our non-return valves are designed to protect your systems with durable, precision-engineered performance. Our valves are built to meet API, ASME, CSA, and ISO standards
Why Are Check Valves So Important?
Check valves, also known as non-return valves, are designed to allow fluid (liquid or gas) to flow in one direction only. When the flow reverses, the valve automatically closes, preventing reverse flow and potential system damage. This passive yet powerful function ensures:
- Protection of pumps, compressors, and pipelines
- Prevention of water hammer and pressure surges
- Reduction in maintenance and downtime
- Isolation of system segments in emergencies
Applications of Non-Return Valves-
- Oil Gas – Pump discharge lines, separators, and flare systems
- Water Wastewater – Backflow prevention in pump stations and treatment plants
- Power Generation – Condensate lines, feedwater control, turbine systems
- Mining Slurry Handling – Abrasive slurry pipelines and tailing lines
- Pulp Paper – Effluent lines, chemical dosing systems
- Marine Shipbuilding – Bilge systems, seawater intake, ballast discharge
- HVAC Fire Protection – Sprinkler systems, heating loops, chilled water supply
Types of Check Valves -
Swing Check Valve
- Classic design with a hinged disc
- Ideal for low-velocity, horizontal flows
- Used in clean water systems and pump discharge lines
Dual Plate (Wafer) Check Valve
- Compact and lightweight with spring-loaded dual discs
- Prevents water hammer
- Common in HVAC and industrial pipelines
Lift Check Valve
- Disc lifts with forward flow and seats during backflow
- Suitable for high-pressure vertical or horizontal pipelines
- Found in power plants and boiler systems
Ball Check Valve
- Uses a spherical ball as the closing mechanism
- Self-cleaning and suitable for viscous, abrasive, or slurry media
- Preferred in wastewater and mining sectors
Cryogenic Check Valve
- Designed for low-temperature services (LNG, LOX, etc.)
- Extended bonnet for insulation and safety
- Used in cryo-plants and gas storage facilities
Non-Slam Check Valve
- Fast-closing, spring-assisted disc reduces water hammer
- Used in high-rise building systems and high-pressure applications
