1. Structure of API 6A Oilfield Choke-plate Type Valve Description

Orifice plate chock valve is molded by two very special tungsten carbide metal plates with impact damage resistance. Changing the concentricity of the up orifice and down orifice by rotation of one of the plate, to achieve the adjustment of liquid or gas flow.
Orifice plate chock valve is used for manifold equipment, 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. The outstanding advantage of this valve is that, it has long service life, and characteristics of damage and wear resistance compared with other kinds of choke valve.
