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 liminates 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)

 

 

• The benefit of swing check valve includes:
  
  Ease of maintenance:
  The key to the design of swing check valves is ease of maintenance. The bonnet assembly such as the hinge and disc for the valve can be removed from the valve by unscrewing a few bolts, and can be maintained. The seat is placed at an angle of 20°, providing tightness even at low back pressure.
  
  The hinge is made of acid-resistant stainless steel (SS316) and is firmly fastened around the shaft with bolts to eliminate play and ensure durability. In the case of limited available space, the hinge can be placed in reverse position. 
  
  Prevent water hammer:
  When a liver and weight are installed, the small-sized swing check valve can be activated by manually moving the lever. It is able to achieve a gentle closing of the seat and an optimal closing speed by adjusting the weight on the lever in order to prevent water hammering.
  
  Water hammer can occur in any piping system that uses valves to control the flow of liquid or steam. A protective device covering the lever and weight can be used as an additional safety measure because it eliminates the risk of injury. The protective device is equipped with a limit switch for remote monitoring. 
  
  Economical option: 
  A swing check valve is a low cost type of check valve, the low cost of the valve allows them to utilize within a wide range of operation as the low project budgets. Swing check valve also provides a larger flow capacity, however, it does not support downward vertical flow, which has the limitation on serving different types of system.

In a swing check valve, the flapper will swing to allow fluid or gas to flow forward. When the flow needs to be stopped, the baffle will swing back to the valve seat and automatically close the valve as the system pressure decreases. The swing check valve is eye-catching due to its large flow.

The usage of the swing check valve is limited to horizontal flow or vertical upward flow due to the fact that the valve itself requires a swing to perform. However, the swing check valve is suitable for various media, including liquid and gas. The general application for swing check valves such as fire fighting equipment, flood control of sewage systems, and toilet flushing mechanisms.





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.
