Manual throttle valve

Manual throttle valve The choke valve as a main part of Xmas tree and manifold is mainly used for controlling the production rate of the oil well. Its working pressure reaches 1000psi. Choke valves can be classified as adjustable choke valves and fixed choke valves. The adjustable choke valve control the effective opening area of the choke bean by rotating hand wheel to drive stem forward and backward, in order to control and adjust the production rate. The fixed choke valve controls and adjusts the production rate by changing the flow bean size The features1.The union used for connecting the bonnet and the body of the fixed choke valves allows fast make-up and break-out 2.Stem tip and bean adaptor are fabricated from special carbide alloys for corrosion and abrasion resistance; 3.Indicator lens with scale marks allows the operator to check the stem's position and actual orifice area; 4.Turn the hand wheel counter-clockwise and the valve will open;turn the hand wheel clockwise and the valve will close
