Description
The CM is a manually operated diaphragm valve, with small overall dimensions that enable easy installation even where space is a premium.
The spindle, not in contact with the fluid, is in metal.
The innovative CDSA - Circular Diaphragm Sealing Area - system offers the following mechanical advantages:
- uniform distribution of the pressure made by the compressor on the sealing diaphragm
- easy internal cleaning
- lower risk of deposit accumulation, fluid contamination and damaging of the diaphragm due to the eventual crystallization
- reduction of the closing handwheel torque

Features
- Pressure rate up to 6 bar (87 psi) at 20°C (68°F): see dimensional table.
- Body in PVC
- Diaphragms in EPDM, FPM or PTFE
- Position indicator as standard
- Adjustable Travel Stop as standard
- Maintenance without disassembling from the plant
- Sealed Hand-wheel
