Theory of Operation

How does an aseptic diaphragm valve work ?

The single layer diaphragm of the DELTA MS4 is made of TFM. The diaphragm, shaft and cone of the DELTA MSP4 is built from one TFM piece. The opening and closing of the valve is performed either by a pneumatic actuator or manually by means of a crank.

During opening and closing, the diaphragm is continuously supported by a unique fan support system, which relieves process pressure on the diaphragm, thus protecting it against overstress and/or pressure spikes. This system significantly increases diaphragm reliability and lifetime.
