Detailed Product Description

ZDL electric control valve

1)        It receives DC signals from regulating instrument and adjusts the flow capacity medium directly, to keep technical parameters steady. The product has a number of advantages such as simple and exquisite structure, light weight, new and original design and large valve capacity.

2)        Compared with pneumatic control valve, electric control valve are more sensitive, convenient access to energy, rapid transmitting and long signal distance etc., therefore be applied to the fields of petroleum, chemical plant, power plant, metallurgy, paper making, pharmacy etc.
