High-pressure globe valves are types of globe valves designed for use in high pressure and high temperature. The valve is operated by use of a manual actuator, or it is automated through an electric or pneumatic actuator. It operates when torque is applied on the handwheel and transmitted via a component known as the stem to the valve disc. The valve disc is tasked with shutting off, starting, and regulating fluid flow. When the stem moves up, it moves with the disc, opening the valve and allowing fluid flow. When it moves downwards, it forces the valve disc to the seat, ensuring zero fluid flow and zero leakage.
The advantages of high-pressure globe valves are suitable for throttling, versatile in size and application, durable, and have high strength for high temperatures and pressure. Applications of these valves are steam power plants, chemicals, oil and gas, and boiler systems, among others. Among the main types of valves made by high-pressure glove valve manufacturers are the Z-pattern valve, angle pattern valve, Y-pattern valve, electric valve, pneumatic valve, welded end valve, and flanged end valve, among others.
