API 6A Wellhead manual & hydraulic Choke Valves

Short Description:

Choke valve is a main component of Christmas tree and designed to control production output of the oil well, the materials of the body and components of choke valve are completely in conformity with API 6A and NACE MR-0175 Standard Specifications, and it is widely used for onshore and offshore petroleum drilling. The throttle valve is mainly used to adjust the flow and pressure of the manifold system; There are two types of flow control valves: fixed and adjustable. Adjustable throttle valves are divided into needle type, inner cage sleeve type, outer cage sleeve type and orifice plate type according to the structure; According to the operation mode, it can be divided into manual and hydraulic two. The end connection of choke Valve is thread or Flange, connected by non or flange. Choke valve falls into: positive choke valve, needle choke valve, adjustable choke valve, cage choke valve and orifice choke valve, etc.

Fixed flow control valves achieve fluid flow control by changing the size of the throttle nozzle to change the throttle area of the liquid. The throttle nozzle is made of ceramic or cemented carbide, which has wear resistance and erosion resistance, and its replacement adopts special tools, which is quick and convenient. The valve body and bonnet are connected by non, which is easy to disassemble.

Orifice plate throttle valves use a rotary fork to actuate the seat assembly, which generally only needs to rotate the fork 90° or 180° to open and close the valve. The two ends of the fork are preloaded and positioned, which improves the rigidity of the fork and reduces its vibration, so that the operation of the fork is smooth and safe. With hydraulic, pneumatic and electric drive devices, orifice plate throttle valve can achieve more accurate adjustment, so orifice plate type throttle valve is widely used.

The needle type throttle valve adopts a forged valve body, which is resistant to high pressure and washout. Manual operation, simple structure, low maintenance cost. Optional standard throttle caliber is numerous.
