Diaphragm Regulating Valve

Diaphragm regulating valves are mainly used in biopharmaceutical fluid control system. The design of valve is completely empty without dead angles, liquid contact parts are high purity stainless steel and PTFE material, so it is very suitable for high purity requirements of processing piping systems. The body structure has a variety of forms and combinations (Please refer to the DONJOY diaphragm valve data).
