Rubber disc check valve

Brief Introduction of rubber disc check valve:

Rubber disc check valve includes valve body, valve deck, valve disc,etc. With the slant design for sealing, the closing time is short, the force occurred by water hammer will be reduced. The disc is made of NBR/EPDM and steel plate pressed under high temperature, which is resistant to erosion.

Brief Introduction of rubber disc check valve:

Rubber disc check valve includes valve body, valve deck, valve disc,etc. With the slant design for sealing, the closing time is short, the force occurred by water hammer will be reduced. The disc is made of NBR/EPDM and steel plate pressed under high temperature, which is resistant to erosion.

Characteristics of rubber disc check valve:

  1. this valve is using full flow area design, which i slow flow loss.
  2. Slant design, better sealing, short closing time, reducing water hammer phenomenon.
  3. reliable sealing, simple structure, convenient to service, repair, and delivery.

Applications of rubber disc check valve:

Rubber disc check valve is widely used in pipeline systems of industries like water supply and drainage system, petroleum, chemical industry etc to prevent the medium from flowing back
