Stainless Steel Globe Valve
MVS Stainless Steel Globe Valve is of Rising Stem Bolted Bonnet Construction available in Plug Type Disc, Flat Disc, Soft Seat Disc, Regulating Disc, Guided Disc plug options. Globe Valve Cast Heavy Duty Body Material options include Cast Steel, Stainless Steel, Duplex Steel in Flanged End Connection.
MVS stainless steel globe valves are heavy duty, outside screw & yoke type, bolted bonnet, rising stem and hand wheel. Valves are highly efficient for services requiring frequent operation and throttling. The internal passage within the valve diverts flow through 90° changes of direction resulting in pressure drop and turbulence. The most advance design features provides the ultimate in dependable, economic flow control. They are available in wide range of sizes and weights. Globe valve are generally considered where moderate control or regulation of flow is required.
Stainless Steel Globe valves are adequate for all service media. Valves are marked with flow direction since they are recommended to install with flow and pressure under the disc. It can also be installed in reverse condition depending upon the conditions. The stainless steel globe Valve is generally faster to operate due to less travel. But requires much force to operate compared to Gate valves.
Special Alloy Globe Valves : All MVS Stainless Steel Globe Valve are available in these Special Alloys like Titanium Alloy, Zirconium Alloy, Nickel Alloy, Hastelloy Alloy, Inconel Alloy, Incoloy Alloy, Monel Alloy, Aluminium Bronze and Duplex Steel.
