Forged Steel Globe Valve

Описание

A forged steel globe valve is an industrial valve used to control the flow of fluids (liquids or gases) in pipelines. It is made from forged steel, offering strength and durability suitable for high-temperature and high-pressure operating environments. Forged steel globe valves are primarily employed for isolating, regulating, or controlling fluid flow and find applications across various industrial sectors.

Here are the key features and components of a forged steel globe valve:

1. Valve Body and Bonnet: The valve body and bonnet are crafted from forged steel to withstand high pressures and temperatures. The bonnet is usually threaded or bolted to the valve body for maintenance and servicing.
2. Valve Disc (Valve Plug): The valve disc, also known as the valve plug, is the movable component that regulates fluid flow. Rotating the valve disc can open or close the valve to control the flow rate.
3. Valve Stem: The valve stem connects the valve disc to the operating mechanism (handle, handwheel, or actuator). Turning the valve stem operates the valve disc to open or close the valve.
4. Operating Mechanism: The operating mechanism is used to manually or automatically control the valve. It can be a simple handwheel or an electric, pneumatic, or hydraulic actuator for automated control.
5. Sealing Mechanism: To ensure valve integrity, sealing mechanisms often employ gaskets, packing materials, or O-rings to prevent fluid leakage.

Forged steel globe valves are advantageous due to their high-temperature resistance, high-pressure capabilities, structural stability, and suitability for challenging operating conditions. Owing to their robust construction and reliable sealing performance, forged steel globe valves are widely used in industries such as petrochemicals, power generation, and metallurgy, especially in situations involving high-temperature and high-pressure fluids. The choice of the appropriate valve type depends on specific process requirements and operating conditions.
