CMDV - Compact diaphragm valve DN 12:15

Compact diaphragm valve with male ends for solvent welding, metric series.

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

Main features:

  • 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

  • Connection system for solvent weld and threaded joints
  • 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 crews 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 eposits, contamination or damage to the diaphragm due to crystallisation
    • operating torque reduction
