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.
