Compact diaphragm valve
The CM is a manually operated diaphragm valve of reduced dimensions and particularly compact structure, ideal for use in confined spaces.
CHARACTERISTICS COMMON TO ALL CM:
- Easy replacement of the sealing membrane
Manual valves
SPECIFIC CHARACTERISTICS CM MANUAL DN 12:15:
- Jointing system for gluing (PVC-U and PVC-C), for threading (PVC-U and PVDF) or for welding (PVDF and PP-H)
- Extremely compact construction
- Internal metal operating parts, isolated from the fluid
- Stem for movement transmission in stainless steel
- Compressor with floating diaphragm support
- Corrosion resistant internal components
- CDSA (Circular Diaphragm Sealing Angle) sealing system which, thanks to the uniform distribution of the shutter pressure on the sealing diaphragm, offers the following advantages:
− Uniform distribution of the shutter pressure on the sealing membrane
− Reduction of the tightening torque of the screws that fix the valve body to the actuator
− Less mechanical stress for all valve components (actuator, body and diaphragm)
− Ease of cleaning of the internal areas of the valve
− Minimization of the risk of accumulation of deposits, contamination or damage to the membrane due to crystallization phenomena
− Reduction of the operating torque
- Completely sealed PAGR control handwheel with high mechanical resistance with ergonomic grip for excellent maneuverability
- Integrated and adjustable closing limiter which allows to limit excessive compression of the diaphragm or to always guarantee a minimum flow of fluid
- Optical position indicator supplied as standard
- Cover in PA-GR with stainless steel nuts completely protected by plastic caps with no areas of accumulation of impurities. Internal tightening profile of the circular and symmetrical membrane
- Stainless steel bolts with the possibility of assembly from above
- Metal threaded inserts for valve anchoring

Valves actuated
SPECIFIC FEATURES CM IMPLEMENTED DN 12:15:
- The valve is insensitive to media containing impurities
- It has a considerable range
- It can be mounted in any position
- It has a very compact structure
- It is actuated by a maintenance-free, dry-running piston
- It has no visible screws and is absolutely free from deposits of impurities
- In the Standard version the valve is equipped with a position indicator
- Piston actuator in PP-GR compact and light with no exposed metal parts, it is particularly suitable for use in harsh and chemically aggressive environmental conditions.
- IXEF piston with high mechanical resistance guarantees high reliability over time without maintenance.
- High visibility optical position indicator protected by a transparent cover with sealing O-Ring.
