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
