The choke valve, a main component of Christmas tree, is designed to
control production rate of the oil well, whose working pressure
reaches 10000psi.Chock valves and positive choke valves. By
rotating hand wheel to drive the stem forward and backward, the
effective opening area of the choke bean is adjusting to control
and adjust the production rate. The positive choke valve is
designed to accomplish control of production rate by changing flow
beans of various bores.
Features:
Manual Choke Valve
The choke valve, a main component of Christmas trees and manifolds,
is designed to control production rate of the oil well and can
handle working pressure up to 10000 psi. It can be classified as
the adjustable choke valve and positive choke valve. In order to
control production rate, the adjustable choke valve uses the stem
tip driven by the rotating hand wheel to adjust the effective area
available for the flow, while the positive choke valve uses flow
beans in different orifice diameters that can be changed.
