Why Choose Plug Valves?
Reliable Isolation
Plug valves are designed primarily for flow isolation, providing a straightforward shut-off arrangement for suitable industrial piping systems.
Quarter-Turn Operation
Many plug valve designs use a quarter-turn movement of the plug, allowing convenient operation between open and closed positions.
Robust Construction
Plug valves can be manufactured with robust bodies and internal components selected according to the operating medium and service conditions.
Multiple Configurations
Different plug valve designs, materials and end connections are available for a range of industrial piping requirements.
Types of Plug Valves
Plug valves are available in several designs to suit different operating conditions, fluid characteristics, pressure requirements and installation arrangements. The appropriate construction should be selected according to the actual application.
Stainless Steel Plug Valve
Stainless steel plug valves are used in suitable applications where corrosion resistance and material durability are important. They can be considered for chemical, process, pharmaceutical and other compatible industrial services.
Carbon Steel Plug Valve
Carbon steel plug valves provide a strong valve body construction for suitable industrial services. The exact carbon steel grade is selected according to pressure, temperature, fluid and applicable specifications.
Cast Iron Plug Valve
Cast iron plug valves can be used in suitable water, utility and general industrial applications where cast iron provides the required compatibility and mechanical characteristics.
Lubricated Plug Valve
Lubricated plug valves use a lubricant around the plug and sealing surfaces to assist operation and sealing in applications for which this design is appropriate. Lubricant compatibility must be considered for the specific service.
Non-Lubricated Plug Valve
Non-lubricated plug valves use engineered sealing arrangements without routine lubrication of the plug during normal operation. They are selected for suitable services based on design and material compatibility.
Sleeved Plug Valve
Sleeved plug valves incorporate a sleeve around the plug to provide the sealing interface. Sleeve material selection depends on the process fluid, temperature and pressure conditions.
Eccentric Plug Valve
Eccentric plug valves use an offset plug arrangement that can reduce rubbing between the plug and seat during operation. They are commonly considered for suitable isolation applications.
Three-Way Plug Valve
Three-way plug valves are designed with multiple ports and can be used to direct or isolate flow between different piping paths, depending on the plug configuration.

Plug Valve Design & Construction
Plug valves consist of a valve body containing a plug with a passage through it. Rotating the plug changes the alignment of the passage with the pipeline, allowing the valve to move between open and closed positions.
Valve Body
The body forms the pressure-retaining enclosure and provides the connection between the valve and piping system. Material selection depends on the pressure, temperature and fluid service.
Plug
The plug is the primary rotating closure element. Its passage and geometry determine the flow arrangement and operating characteristics of the valve.
Stem
The stem connects the operating mechanism to the plug and transfers the required rotational movement. Stem construction depends on the valve design and material specification.
Seat or Sleeve
The sealing arrangement may use a sleeve, elastomer, PTFE or metal seating system depending on the valve construction and process conditions.
Operating Mechanism
Plug valves can be operated manually or equipped with suitable gearboxes, pneumatic actuators or electric actuators according to valve size and operating requirements.
