A valve is a crucial industrial component for controlling the flow of fluids and gases. SVR Global is a renowned valve manufacturer in USA that provides industrial-grade valves enabling vital industries to operate safely, cleanly, and more efficiently. Our mission is to provide high-quality reliable valves at reasonable costs with prompt delivery for industrial and commercial applications. With unparalleled expertise in efficient flow pathways and mechanical design, SVR Global has established itself as the premier manufacturer of the next-generation valves.
SVR Global is the leading check valve manufacturer in USA that provides you with an extensive range of quality products. A wide range of check valves is available at SVR Global.
A check valve is a mechanical device that allows only unidirectional fluid flow. They have two media ports, one inlet, and one output. They are called 'one-way valves’ or 'non-return valves' since they only allow media to flow in one direction.
Check valves are completely automatic and require no human or external control to operate.
They operate on the differential pressure principle. If the upstream pressure is greater than the downstream pressure, the check valve will open. If the pressure downstream is higher, the valve will close, preventing backflow. Closure can alternatively be done by the check mechanism's weight, a spring, or a combination of the three.
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
- Used as a backup and safety system
- Self-actuated
- Fast-acting
- Backflow protection is important for pumps and compressors.
- Reduce downtime and production losses.
- Avoid water hammer.
- Reduce unexpected valve failure.
- Maintenance expenditures are reduced.
- There are only a few moving pieces.
- Reduced footprint
- Adaptable to changing flow conditions
- Operating without the use of electricity
Disadvantages of Check Valves:
- Non-operational in pulsating system
- The closing part may shut, resulting in damage and wear.
- Work in a completely confined environment.
- It is really impossible to tell whether they are open or closed.
- Internal components cannot be examined.
- Occasionally, discs become caught in the open position.
- Slamming discs are noisy
- Hammering with water
- Problems with reverse flow
Industries that use Check Valves:
Check valves are used in Sewage, water treatment, medical, chemical processing, power generation, pharmaceutical, chromatography, agriculture, 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.
