Body Material: SS316L, SS316L VAR,SS316L VIM-VAR By combining two LD or HD series diaphragm valves into one,the dead zone is minimized to the greatest extent through Low Pressure：250 pisg ( 17.2bar), High Pressure; 3000 pisg (207bar) a common flow path, and the degassing performance is excellent. While maintaining the basic performance of the original valve,the most compact piping system can be designed through Suitable assemble and pack for the semiconductor industry that requires ultra-high purity. Every product undergoes helium leak test before being released to market.
