SED Diaphragm valves Steripur 207-30
Romynox delivers Steripure diaphragm valve series SED for high purity applications in the pharmaceutical, food, fine chemical and cosmetic industries. This valve is available in two different designs. The type 207.30 is available in the control function fail safe close and performs at a higher working pressure for standard application. The type 207.25 in control function fail safe close is mainly designed for filling applications or all other where the working pressure is lower.
High cycle stainless steel piston actuator with double piston.The valve is predestined for applications with high purity, dirty and aggressive fluids, and gases. Smooth surfaces, no explored nuts, no edges, and outside self-draining in all assembly, positions describe the optimised wash down design. The Steripure is used where diaphragm valves entirely of stainless steel add value, such as clean rooms or aggressive (corrosive) environment.
