SED – Steripur 217.25 Diaphragm valve

Romynox supplies Steripur membrane valves from SED for high purity applications in the pharmaceutical, food and cosmetic industry and fine chemistry.

One advantages of this design are a longer diaphragm life time 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 fail safe open and double acting for standard working pressures.

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, this makes for a Very Optimised wash down design. The Steripur is used where diaphragm valves entirely of stainless steel add value, such as clean rooms or aggressive (corrosive) environment.

features

• The stainless steel actuator with stainless steel piston has a long service life, and endures many (repeating) cycles
• Compact design, which provides advantage in multiport bodies and manifold valve assemblies
• Low air volume, but high switching speed
• The air connection to the actuator can be placed at the four different positions (with 90° rotation) in relation to the flow direction, so that there is always a position suitable for the setup.
• CDSA sealing concept
• Flexible membrane suspension
• The polished stainless steel surface is ideal for sterile cleaning procedures
