KSB's valve range includes the following SISTO type series:
Benefits of the SISTO diaphragm valve
Contact with the fluid is ruled out for all moving parts.
High operating reliability
The thrust bearing minimises the closing torques required.
Optimised long-term operation
The position indicator with integrated stem protection prevents ingress of contamination.
Excellent functional reliability
Increased functional reliability of the diaphragm thanks to balanced diaphragm suspension. The SISTO diaphragm valve also features an optimum hydraulic design with a very low resistance coefficient.
The SISTO diaphragm valve has no hygienically critical dead volumes. Its optimised hydraulic design allows complete flushing of the valve interior.
Absolutely reliable shut-off and sealing
A single sealing element, the diaphragm, provides hermetic sealing to atmosphere and perfectly tight shut-off, ensuring a long service life and reliable operation.
Long service life
The diaphragm support increases valve life and extends the pressure limit of the diaphragm.
