Description
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.
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 207.25 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 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.
