Steripur 417 SED Diaphragm Valve
SED Diaphragm Valves
Romynox delivers Steripur diaphragm valve series SED for high purity applications in the pharmaceutical, food, fine chemical and cosmetic industries. Compact design, the outside diameter of the actuator is the same size as the bonnet flange. The Steripur is used where diaphragm valves entirely of stainless steel add value, such as clean rooms or aggressive (corrosive) environment.
Smooth surfaces, no explored nuts, no edges, and outside self-draining in all assemblies gives an optimised wash down design. The outside diameter of the actuator is the samen size as the bonnet flange. This gives advantages in multiport bodies and manifold valve assemblies.
The Steripur 417 DN 15 - 50 mm is the new design of the former Steripur 407 DN 15 - 50 mm.
