Globe valves are used generally, because of the comparatively small roughness between the sealing surface when open or closed. Also globe valves are durable, open height is small, manufacturing is easy and convenient maintenance, etc. It can be used not only in the low pressure but also high pressure.
Globe valve closed depend on stem pressure, make the disc sealing surfaces and seat sealing surface tightly. To stop the flow of media, Globe Valves only allowed a one-way medium flowing direction, so globe valves are installed directional.
A heavy duty globe valve to API and BS standards. The seat ring and Wedge Disc are ground and lapped to a mirror finish that provides matching sealing surfaces. A plug type disc is supplied as standard with flat and regulating type discs available on request. Heat treated stainless steel STEM with precision machined ACME threads for long lasting service. Machined Backseat Bushing to provide a secondary metal-metal stem seal. Rising Stem gives open and closed indication of position with large diameter Hand wheel for easy operation. Austenitic ductile iron YOKE SLEEVE gives resistance to heat, corrosion and wear. Two piece self-aligning GLAND BUSHING and GLAND FLANGE to prevent damage with high strength alloy steel STUD BOLTS.
