Our BS1873 Cast Steel Globe Valve is one kind of important oil and gas industry valves. The BS1873 cast steel globe valve’s trim is more than just a closure element (because a throttling valve does more than just open or close), but rather  it is a regulating element that allows the valve to vary the flow rate against the position of the valve according to the flow characteristic, which may be equal percentage, linear, or quick-open. Typically, this trim consists two key parts: the plug, which is the female portion of the regulating element, and the seat ring, which is the female portion. The portion of the plug that sets into the seat ring is called the plug head, and the portion that extends up through the top of the globe valve is called the plug stem.

The flow direction of BS1873 Cast Steel Globe valve is defined b the manufacturer or the application, although in most manual applications, flow direction is almost always under the plug. Seating the plug against the flow provides constant resistance but not enough to be insurmountable. With under-the-plug flow, the valve is relatively easy to close as long as the fluid pressure and flow rate are low to moderate. In addition, under-the-plug flow provides easy opening by the flow pushing against the bottom of the plug.

GGC valves means gate globe and check valves, the gate valve of them is usually used for on-off function. the swing check valve is for non return valve function. The globe valve is maily for regulating function as well as on-offer. The BS1873 cast steel globe valve can be amended design to be globe check valve which has non return valve function.
