Product Details

ZDSJ series electronic straight stroke electric angle regulating valve, with German import PS series straight stroke electric actuator, we can adjust the parameters of pressure, flow, temperature, liquid level etc.. Has the advantages of small size, light weight, small leakage, flow path is simple, low resistance, to regulate the use of the pressure differential, high viscosity, suspended solids and granular materials containing liquid, can avoid coking, jam, but also facilitate the self cleaning and water, the angle type control valve is generally used in the bottom side of the occasion, because this can make the adjustment has better stability. Electronic electric angle type control valve, electric angle type control valve, electronic control valve.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, diameter, drive, etc.. Specific please contact or online advisory contact.
