Butterfly - Serie 10s

RMT VM Butterfly Series 10s is an eccentric disc butterfly valve available in three different construction line.

Butterfly High-Performance Plain Disc - Serie 11

The Serie 11 is a double-eccentric disc Butterfly Control Valve mostly used in applications with large flow rates and moderate pressure drop across the valve.
Provided with a very easy to change and PTFE based or metal-to-metal type sealing ring, this design guarantees a reduced torque and seal wear by minimizing its contact with the disc.
These features serve the valve with high performances, application flexibility and long service life.

Main characteristics:
  • DN from 6’’ up to 80’’.
  • Wafer, lug, double-flanged construction.
  • Solid construction, low friction bearings.
  • Equal percentage inherent characteristic.
  • Leakage Class IV by Standard, Tight Shutoff Class V and Class VI
Many options:
  • Metal/soft seated.
  • Packing fugitive emission compliant.
  • Live loading packing.
  • Exotic materials.

Butterfly High-Performance Wing Disc - Serie 12

The Serie 12 is a high performance double-eccentric Butterfly Control Valve with winged disc allowing the valve to have high performances, application flexibility and long service life.
This design:

  • increases the recovery factor and the cavitation index by the control of the flow in cavitating services on liquids and by the noise abatement on gas with high ΔP.
  • couples the capacity of a rotary control valve of managing high flow rates with a resisting cavitation and / or noise abatement trim.
Main characteristics:
  • DN from 6’’ up to 56’’.
  • Wafer, lug, double-flanged construction.
  • Solid construction, low friction bearings.
  • Equal percentage inherent characteristic.
  • Wings extended up to 90°, for very critical services.
  • Leakage Class IV by Standard, Tight Shutoff Class V and Class VI.
Many options:
  • Packing fugitive emission compliant.
  • Live loading packing.
  • Exotic materials.
