Description

The FIP Diaphragm Valve VM 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%)

Features

  • Pressure rate up to 10 bar (145 psi) at 20°C (68°F): see dimensional table.
  • Body in UPVC
  • Diaphragms in EPDM, NBR, FPM or PTFE
  • Position indicator as standard
  • Maintenance without disassembling from the plant
