Double sealed automatic control valve is in the multi-function hydraulic control valve and many other excellent performance on the basis of the valve.
It is an electric butterfly valve with check valve function, and through the fast closing and slow closing action to eliminate water hammer hazards, protection of water pump and pipe network system security, widely used in electricity, metallurgy, urban construction, water supply and drainage Such as automatic pumping station system.
- three eccentric structure
- reducing the friction torque
- anti-sediment and pressure automatic compensation effect.
- Slow closing device and valve plate linkage opening and closing, automatic fast closing
- installed valve position transmitter, send 4 ~ 20mA analog valve position signal to the remote control room, to achieve remote monitoring.
