VM PP-H - Diaphragm Valves

FIP Diaphragm Valve VM series is particularly suitable for regulation or on-off operations with dirty or abrasive fluids. The hand-wheel operator and the diaphragm type sealing, allow precise regulation and reduce the water hammer.
The innovative CDSA - Circular Diaphragm Sealing Area - system (up to DN50)offers the following mechanical advantages: - uniform distribution of the pressure made by the compressor on the sealing diaphragm
- up to 20% of bolt tightening torque reduction
- reduced mechanical stress on all valve components (actuator,body and 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 of the manual valves (up to 40%)

• VMDM - Diaphragm valve with metric series spigot ends for socket fusion
• VMUIM - Diaphragm Valve with unionised metric series plain female ends for socket fusion
• VMOM ISO-DIN - Diaphragm Valve with DIN 2501 backing rings
• VMOM ANSI - Diaphragm Valve with ANSI 150 backing rings

CM PP-H - Compact Diaphragm Valves

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

• CMDM - Diaphragm valve compact with metric series spigot ends for socket fusion
• CMIM - Diaphragm valve compact with metric series plain female ends for socket fusion
• CMFM - Diaphragm valve compact with BS parallel threaded female ends
• CMUIM - Diaphragm valve compact with unionised metric series plain female ends for socket fusion
