The throttle manifold is to control the kick thenecessary equipment, the implementation of oil and gasWells pressure control technology, Under the conditiorof closed wellhead control device, using the throttlevalve opening and closing,casing pressure, maintain andcontrol pressure balance or maintain the bottom holepressure is always slightly greater than the formationpressure, avoid the happening of the overflow andblowout. In addition, when implementing shut-in, canthrough the throttle valve pressure to achieve soft shut-in, when the borehole pressure is too high, can be usecto spray to protect the well's mouth. Choke manifold andoptional controller to realize the remote control.I plant production of throttle manifold withAPI Spec 16 cspecification; And we can accordingto customer's special requirements for design andproduction.
