API6A Choke valves

The valve is a kind of multistage pressure reduction and high-pressure difference regulating valve and can be applied to control the high temperature, high pressure and high pressure difference as well as the flow and pressure of fluid containing solid particles. It adopts nozzle, labyrinth throttle to form the front and back multistage throttle; the valve spool and valve seat adopt hard and soft seal pairs to separate the sealing face and the throttling face, which has improved the throttling ability and sealing reliability of the valve and has the merits of reliable sealing, low noise, little vibration, throttle and cut-off pressure reduction, portable and flexible on and off, etc. The valve is especially suitable for the throttle and cut-off under high pressure. On the condition of high pressure, it possesses the function of pressure reduction and had a long service life.
