Introduction for cast steel globe valve:
The globe valve have anther name is stop valve,OS & Y Type, Rising Stem, Bolted Bonnet ASA / ND Design
The Globe Valves from our comapny are outside screw, rising Stem, bolted bonnet cnstruction, threads are away from the line fluid and easy to lubricate.
The Globe Valves are generally available with plug type disc, they also are the forging, so it is very strong, the disc can rotate around itself,so it no need with the stem rotate simultaneously ,when the workers open and close the valve(Rotary the stem),this This structure design ensures the disc is not easy to wear . which is designed to give leak tight seating over a long period of in built wear life. the seat ring of the globe valve is replaceable type, the threaded seat ring which has large taper area that is for ample seating. Two nos. slots are provided on seat ring of body, which is for easy removal for servicing at site. Welded type seat ring & Integral seat ring are also available in globe valve. all of stems are made from solid one piece construction.they also are forging, the yoke bush of globe valve has a long thread engagement for accurate stem alignment. The standard range of our company's globe valve in sizes of up to 12 (300mm)
The features for cast steel stop valves:
Design standard as per: BS1873,ASME B16.34, GB/T 12235, DIN3356
Generally, lift of disc is just 1/4 of the valve seat port, ensuring a short opening and closing time.
Only one sealing face is designed on the valve body and valve disc,
For large size valves will be designed with main disc and vice disc type, and medium flow from up disc to down disc.
Full stellite overlay seat sealing surface
Good for manufacturing process and easy to maintain.
The valve is designed as a back seat sealing structure.
Use flexible and woven graphite collaboration type packing or PTFE packing(V type).
Optional by-pass design,
Top flange size as ISO5211 design easy to install pneumatic actuators and electric actuators
