What Is an Alloy Steel Plug Valve?
An Alloy Steel Plug Valve is a quarter-turn valve that uses a cylindrical or tapered plug with a flow passage through it. Rotating the plug approximately 90 degrees opens or closes the flow passage.
Plug valves are primarily used for on/off isolation and can be supplied in lubricated, non-lubricated, sleeved, lined, expanding and other configurations depending on the application.
For demanding oil & gas and process services, the plug valve design and material selection should be based on the actual pressure, temperature and process medium.

Stem
The stem transfers operating torque from the handwheel, gearbox or actuator to the plug.
Seat
Seat construction depends on the valve type. Possible configurations include metallic seating, PTFE-based sleeves, engineered polymers and other materials suitable for the specified service.
Bonnet / Cover
The bonnet or cover provides access to internal components and supports the operating mechanism.
Lubrication System

Types of Alloy Steel Plug Valves
Alloy Steel Lubricated Plug Valve
Lubricated plug valves use a lubrication system between the plug and body to reduce friction and support sealing.
They can be considered for demanding industrial applications where operating torque and sealing performance are important.
Alloy Steel Non-Lubricated Plug Valve
Non-lubricated plug valves use a sleeve or other engineered sealing arrangement instead of continuous lubrication.
They are commonly considered for applications where maintenance requirements and process compatibility are important.
Alloy Steel Sleeved Plug Valve
Sleeved plug valves use a non-metallic sleeve around the plug to provide sealing between the plug and body.
Alloy Steel Expanding Plug Valve
Expanding plug valves use an expanding mechanism to create sealing contact. Certain designs can provide double-block-and-bleed functionality.
Alloy Steel Jacketed Plug Valve
Jacketed plug valves incorporate a heating or cooling jacket around the valve body for services where temperature control of the process medium is required.
Alloy Steel Full Port Plug Valve
Full-port designs provide a flow passage that closely matches the connected pipeline bore, reducing flow restriction.
