The check valve disc will close when the two pressure are equaled. So that the flow goes one way in the pipeline, and prevent the fluid flowing back, avoid the accidents.

Design Standard: DIN 11851-98 SMS3008 ISO 2037-92
Test Standard: GB/13927-200
Material:
Steel parts: SS304(1.4301), SS316L(1.4404)
Seal: EPDM. VMQ, FPM

Technical Data:
If the check valves are installed in a vertical pipe. It need approximately 200~600kpa(2~6bar)to open. Maximum pressure for conveying material is 800Kpa(8bar). Using temperature scope is based on the material of seal. Usually use EPDM. It is -10 degree~+140 degree
(For property of seal, please refer to appendix. )
