Product details

The dual plate check valve is a general purpose check valve that is stronger, lighter in weight and smaller in size than traditional swing check valves.

The dual plate check valve utilizes two spring-loaded plates attached to a central dumpling chain pin. When the flow is reduced, the plates are closed by the action of the torsion spring, and there is no need for reverse flow.

This design provides the dual advantages of no water hammer and no impact at the same time.

Project case

A customer in Pakistan purchases check valves, gate valves, pipe fittings, etc.

Main products:

check valve, gate valve, pipe fittings, etc.

Project description:

The client in this case is from Pakistan and is a large-scale local valve distributor. They have their own store locally and often import some valves from abroad to store or supply to local customers.

This client has cooperated with WESDOM many times. Almost every once in a while, they will contact the foreign trade salesman of WESDOM. They bought a batch of valves from WESDOM and stocked them in their store.

Through many cooperations with WESDOM, the two sides have established a very close cooperative relationship. Of course, they contacted WESDOM without hesitation, and purchased check valves, gate valves, pipe fittings, etc. from WESDOM.

Client feedback:

We have worked with WESDOM many times and have been very satisfied each time. We are very willing to maintain a long-term cooperative relationship with WESDOM.

Features

  1. Lightweight, so easier to handle and self-supporting. More compact and well-structured design.
  2. The same valve can be installed horizontally or vertically.
  3. Due to the spring assisted closing, only the double plate check valve can be installed upside down.
  4. Reduced pressure drop and energy loss regardless of pressure rating.
  5. Efficient and reliable sealing under most flow and pressure conditions.
  6. The valve closes before the flow reverses and the velocity is zero.
  7. Water hammer is almost non-existent.
  8. Long service life and trouble-free operation.
