sanying for all diaphragm valve conducted a comprehensive technology update in 2015. The upgraded design more in line with GMP, ASME BPE, EHEDG and 3A of the technical requirements of high purity. Especially for handling dead angle reached requirement ≤ 1D to ≤ 3D.
Advantage:
1.Reliable, long life diaphragm - available in high performance EPDM+PTFE for continuous steam operation at temperatures up to 150 °C
2.Hygienic design - high-grade valve bodies and low Ra surface finishe
