We are pleased to introduce our newly developed stainless steel Manual valves for special gases.

Springless diaphragm design.

Particle-free & minimum dead space.

• An excellent Cv value of 0.8 to expand gas application
  The valve passage diameter is 7mm and the flow rate is 2.5 times compared with the current valve.
• Easy refurbishment
  Because of the seat plug, the insert and diaphragm are assembled in one package making maintenance easy.
• Double-sealing design Two
  (2) o-rings and a leak port plug on the upper part of the diaphragm minimizes leakage if the diaphragm is broken.
• Non-loosening packing nut
  The fixing bolt protects the package nut from loosening when the valve is subjected to chocks during transport and usage.
• Tied-diaphragm type
  Solid and precise welding technology ensures high durability
• Recessed pressure relief device
