Product Name: Electric V-notch Cut Ball Valve
Product introduction:
Electric V-notch Cut ball valve configured with the intelligent actuator which can make the proportional control receives the ON - OFF or 20 MAC or 1-4-5 VDC signal from high precision electric actuators and indicates the angle of direct instruction and feedback. The switch type product can operate only by the single-phase power to make the parameters regulation including pressure flow temperature the level of liquid and so on.
The V-notch cut in disc can rotate reversely & correspondingly with metal seal to produce shear force to cut off fibre and prevent the block. This valve is special suitable for mud and fibrous media and suspended solids containing minimal media.
