The CM is a manually operated diaphragm valve of reduced dimensions and particularly compact structure, ideal for use in confined spaces

  • Connection system for solvent weld
  • Extremely compact construction
  • Internal operating components in metal totally isolated from the conveyed fluid
  • Valve stem in STAINLESS steel
  • Compressor with floating diaphragm support
  • Easy to replace diaphragm seal
  • Corrosion-proof internal components
  • CDSA (Circular Diaphragm Sealing Angle) system offering the following advantages:

– uniform distribution of shutter pressure on the diaphragm seal
– reduction in the tightening torque of the screws fixing the actuator to the valve body
– reduced mechanical stress on all valve components (actuator, body and diaphragm)
– easy to clean valve interior
– low risk of the accumulation of deposits, contamination or damage to the diaphragm due to crystallisation
– operating torque reduction

Handwheel in PA-GR,completely sealed, high mechanical strength with ergonomic grip for optimum manageability
Integrated adjustable torque limiter designed to prevent excessive compression of the diaphragm and always guarantee a minimum fluid flow
Optical position indicator supplied as standard
Bonnet in PA-GR with STAINLESS steel nuts fully protected by plastic plugs to eliminate zones where impurities may accumulate. Internal circular and symmetrical diaphragm sealing area
STAINLESS steel bolts, can also be inserted from above
Threaded metal inserts for anchoring the valve
