Product Description

Product Description:

Orifice choke valve is used for manifold equipments, such as drilling, fracturing, mud circulating, ground high-pressure gas injecting and producing, etc.
The most remarkable feature of the valve is that pressure difference between inlet and outlet can press the two orifice together closely to realize the function of sealing and cutting off when it is closed. Especially in emergencies such as sudden rise or sudden drop of the pressure because of leakage, it closes and cuts off automatically through pre-set pressure signal value of high and low pressure sensor. Thus, accidents can be avoided.
It’s main advantage is the long working life and elevated erosion/corrosion resistance in comparing with other choke valves.The choke plates are made from two pieces of solid special carbon tungsten.
