V-notch Electric Ball Valve
Description
V-notch electric ball valve is a electric actuator of electric-unit combination instrument with the advantages such as small size, rigid, high precision, sensitive action, which adopts the direct feedback and indicator when the angle changed to realize the proportional regulating in receipt of the on-off, 4-20mAC or 1-5VDC signal. The switch type product can operate only by the single-phase power, also can realize the parameters regulation including pressure, flow, temperature, the level of liquid and so on. The plug with the V-notch incision can rotate reversely & correspondingly with metal seal valve 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.
