Description
This valve is available in two different designs. The type 217.30 is available in the control function fail safe close (NC) and performs at a higher working pressure for standard application.
Advantages of the type 217.25 are a very high cycle life and a smaller overall dimensional height. Type 217.25 is available in control functions fail safe open and double acting for standard working pressures.
Description
Romynox supplies Steripur membrane valves from SED for high-purity applications in the pharmaceutical, food, and cosmetic industries and fine chemistry.
One advantage of this design is a longer diaphragm lifetime because there spring force is less. Other advantages of this design are a very high cycle life and a smaller overall dimensional height. Type 217.25 is also available in control functions that fail-safe open and double acting for standard working pressures.
An advantage of the Steripur 217.30 Diaphragm valve design is the longer diaphragm lifetime because the spring force is less. Other advantages are a very high cycle life and a smaller overall dimensional height.
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, make for a Very Optimised wash-down design. The Steripur is used where diaphragm valves entirely of stainless steel add value, such as in clean rooms or aggressive (corrosive) environments.
