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.

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
