HCR Valve – HCR stands for High Closing Ratio or Hydraulic Control Remote. The HCR valve is a hydraulically operated gate valve. This valve is used on diverter systems and choke/kill lines leading from the blow out preventers. The advantage of the valve is that it can be operated remotely.
Choke Manifold – This is a system of valves and lines which are attached to the choke line, and in some cases, kill line. The manifold is used to help control a well that has kicked by diverting the flow to various functions such as an adjustable choke. It is designed for versatility in diverting the mud flow after experiencing a kick.
Kill Manifold – Kill manifolds are a necessary piece of equipment in well-control. They are used to pump drilling fluid into a well barrel or inject the water into the wellhead.
