VQ971H-16P electric V type ball valve
Electric wafer v-shaped ball valve features:
Electric wafer v-shaped ball valve with DTR series electric actuators, without the other match servo amplifier, with input control signals (4 ~ 20 madc or 1-5 adc) and single phase power supply can control operation, Ming jing company realize the parameters such as pressure, flow, temperature, liquid level adjustment.On the valve core to open a v-shaped incision, shear force and hard seal seat opposite rotation, fiber can be cut and prevent death.Has the flow capacity, high controlling precision, adjustable than the big, good sealing, light weight, etc.Suitable for in addition to the small diameter, Angle, tee connection outside most of the occasion, is the best products to replace imported products, especially suitable for mud and contains fibrous medium, and it has a tiny adjustment of suspended solid medium.Widely used in paper industry, sugar, oil, chemical, metallurgical industries such as industrial process automatic control system.
