ZDSJ series electronic straight stroke electric angle regulating valve

1、 Product Details

Product model: ZDSJ

Product Name: Electronic Straight stroke Electric Angle Regulating Valve

ZDSJ series electronic straight stroke electric angle regulating valve, equipped with German imported PS series straight stroke electric actuator, realizes the adjustment of parameters such as pressure, flow rate, temperature, liquid level, etc. It has the advantages of small size, light weight, low leakage, simple flow path, and low resistance. It is used for regulating liquids with high pressure difference, high viscosity, suspended solids, and particulate matter, which can avoid coking and blockage, and is also easy to clean and water clean. Angle valves are generally used in situations where the bottom inlet and outlet are used, because this can make the regulation more stable
