SISTO-CT Diaphragm valve T-valve

SISTO-CT is a diaphragm valve designed as a T-valve, which has a long service life due to its unique placement of the diaphragm. The diaphragm valve also ensures an improved process, as no tension is applied to the diaphragm itself.
  • All SISTO valve bodies are made of bar steel
  • SISTO has a very compact actuator that makes separation from valve body very easy
  • From DN25, the diaphragm is supported by a spring, so that the actuator pressure is distributed over the entire surface
  • All valves are PN16
Product Number:SISTO_CT

SISTO has a unique design of both the valve part, the diaphragm and the actuator which is second to none.
