Product Description

One of the most significant benefits of the high pressure check valve is to prevent water hammering, and it is almost visible or possible in different applications. It protects compressors and pumps from any damage due to water pressure. It causes a low-pressure drop, which can also help to save power or energy.

High pressure check valve reduces or eliminates the chances of sudden valve failure. These valves are flexible, which can facilitate in coping with variable flow conditions. In many applications, it can also be used to reduce downtime. Hence, these benefits can also vary in different applications.

Applications:

• For liquid media (e.g. water, hydraulic oil) in high-pressure applications
• Test benches (e.g. for hydraulic components)
• High-pressure panels
• Wellhead control panels (WHCPs) and hydraulic power units (HPUs)

• High repeatability and improved sealing through self-centring piston
• Redundant sealing:
  • With O-ring and metal cone
  • Leak-tested tightness in accordance with BS6755 / ISO 5208 leakage rate A
• Metal seat:
  • No soft sealing material
  • Long service life
  • High temperature resistance

Check valves are commonly installed in systems that can't accommodate backflow as they allow flow in just one direction. It uses a pressure differential to work, that is, the pressure on the inner side is more than the outer side when the valve opening is done. Peradventure, there's insufficient pressure for the inner side, the valve closes. However, they differ from other valves as they operate without handles, actuators, levers, or workforce. 






In pipes and similar devices and equipment, check valves are generally used to prevent a reverse flow by allowing materials or fluids to flow in only one direction. Despite their various forms, sizes, and functions, these valves generally operate based on the same principle. 

The primary components of a check valve include the Body,Body Seats,Gasket,Cover Plate,Hinge,Nuts,Washer.
