Product Details

Chinese low price and high quality cast iron gate valve

Valve suitable working medium is water, oil, gas, operating temperature t≤ + 150 ℃, the interface is a cylindrical pipe thread to ISO228. Valve is off pieces (gate) to move along the axis perpendicular to the direction of the channel valves in the pipeline mainly as cutting medium, namely the use of fully open or fully closed. Advantages gate is a small fluid resistance, the torque required to open and close small, medium flow unrestricted, fully open the seal surface by erosion of the working medium is small, simple structure, the manufacturing process is better, is the application of a wide range of valves category.
