Renewable Disc Plug Type Globe Valve Flexible Graphite MSS SP-25 B16.34
Globe Valves
The globe valve is used for throttling flow control. Shut off is accomplished by moving the disc against the flow stream rather than across it as in the case with a gate valve. The flow pattern through a globe valve involves changes in direction, resulting in greater resistance to flow, causing high pressure drop. The globe valve is an excellent valve to use for on-off service, but is highly suited for frequent cycling and control of fluids anywhere in amount or volume between the open and closed positions.
The globe valve must be installed in the proper relation to the media flow as indicated by the flow direction arrow marked on the valve body. This valve is considered uni-directional and must be installed with the pressure side or inlet under the seat.
Our globe valve product line are manufactured as full port, with threaded, socket-weld, flanged and butt weld ends. Pressure classes include 150 through 1500. From our Houston, Texas manufacturing facility, we offer valves in the following materials: CF8M, CF3M, CF8, CF3, CK20, CG8M, CF8C, CN7M, CW12MW, CY40, CW6MC, N12MV, N7M, M35-1, CZ100, CD3MN and many others.
