The Main Types of Forged Steel Gate Valves

The main role of forged steel gate valve in the pipeline is to cut off, is a very wide application of a valve, the general diameter DN ≤ 50 cut off the device selected this forged steel gate valve. When the valve is fully open, the sealing surface eroded by the medium is smaller than globe valve. Shape is relatively simple, casting process is better. So, what types are forged steel gate valve? According to the gate construction to classify.

Parallel forged steel gate valve, sealing surface is parallel to the vertical center line. In the parallel type of forged steel gate valve, some valves install wedge, there are also between the gate with a spring, the spring can produce preload, is conducive to the gate of the seal.

Wedge forged steel gate valve, sealing surface and the vertical center line create into a certain angle, that is, two sealing surface into a wedge-shaped forged steel gate valve. Generally, the higher the working temperature, the greater the angle, to reduce the possibility of wedging when the temperature changes.

API, ANSI globe valve, ball valve, gate valve and butterfly valve are our main product. As one of valves manufacturing leaders in China,we produce all kinds of types valves with professional technology.
