Advantages of KEMUS valves:
1) According the European standard, we choose CW617N brass.
2) With SS304 spring, the valves can be used in longer time, and the opening pressure is more stable.
3) The thickness of valve's body can meet the requirement of PN40 safety valve.
4) We choose PTFE or Viton as the sealing material if the working temperature is not high, or process a conical surface to ensure a better seal effect when it has to use metal material.
We company have other valves: gate valve, check valve, ball valve, butterfly valve, safety valve, globe valve, plug valve, etc....
