Industrial Plug Valves for Reliable Flow Isolation
Robust plug valve solutions designed for dependable flow isolation, quick operation and demanding industrial process applications.
Compact Rotary Valve Technology for Reliable Process Isolation
Plug valves are quarter-turn rotary valves that use a cylindrical or tapered plug with a flow passage. Rotating the plug aligns or blocks the passage to start or stop process flow.
Their compact operating mechanism and fast quarter-turn action make plug valves suitable for a variety of industrial isolation and flow-control duties. Depending on the design, they can also be configured for different sealing arrangements and flow paths.
Sleeved Plug Valves for Demanding Process Applications
FMV Valve Automation offers Industrial Plug Valve solutions, including Sleeved Plug Valves, for applications where reliable sealing and controlled process isolation are important.
Industrial Plug Valves
Quarter-turn rotary valves designed for efficient opening, closing and isolation of industrial process flow. The rotating plug provides a direct operating mechanism for controlling the flow passage.
Sleeved Plug Valves
Sleeved plug valves use a sleeve between the plug and valve body to provide the sealing interface. The sleeve can also provide protection between the process medium and body surfaces.
Engineered for Efficient Industrial Flow Isolation
Plug valve construction offers several functional advantages for industrial applications where quick operation and dependable isolation are required.
Quarter-Turn Operation
Rotary plug movement provides fast opening and closing compared with valves requiring multiple turns of a handwheel.
Reliable Flow Shut-Off
The plug rotates into a closed position to block the flow passage and isolate the process line.
Compact Construction
Rotary operation provides a compact valve arrangement that can be advantageous where installation space is limited.
Sleeved Sealing Option
Sleeved plug valve designs use a sleeve as the sealing interface between the plug and valve body.
Industrial Media Compatibility
Properly selected plug valve designs can be used for a range of compatible liquids, gases and selected difficult media.
Automation Ready
Quarter-turn operation allows suitable plug valve configurations to be integrated with compatible actuation systems.
How an Industrial Plug Valve Works
A plug valve controls flow through the rotation of a cylindrical or tapered plug inside the valve body. The plug contains a flow passage that aligns with the pipeline when the valve is open.
Open Position
The plug port aligns with the pipeline flow path, allowing process fluid to pass through the valve.
Rotary Movement
The stem rotates the plug around its axis to change the position of the internal flow passage.
Flow Passage Blocks
As the plug rotates away from the open position, its solid section moves across the flow path.
Closed Position
The plug reaches the closed position and the sealing system isolates the process flow.
Plug Valves Across Industrial Process Systems
Plug valves can be considered for applications requiring fast isolation, compact construction or specialised sealing and flow-path arrangements.
Oil & Gas
Suitable for selected pipeline and process isolation duties involving compatible oil and gas services.
Chemical Processing
Sleeved and other suitable plug valve arrangements can be selected for compatible chemical process media.
Petrochemical Plants
Used in selected process and utility services where reliable rotary isolation is required.
Water & Wastewater
Suitable plug valve configurations can be considered for selected water, sludge and wastewater applications.
Mining & Slurry
Properly selected plug valve designs can support isolation of selected abrasive or solids-bearing process streams.
Power & Process Plants
Applicable to selected utility and process systems requiring dependable flow isolation.
Practical Advantages for Industrial Flow Control
The quarter-turn plug valve design provides a practical solution for applications where quick operation and dependable isolation are important.
Fast Quarter-Turn Operation
The rotary mechanism allows the valve to move between open and closed positions through a short operating movement.
Compact Installation
The rotary design can offer a compact alternative for selected isolation applications where available space matters.
Effective Process Isolation
The plug and seating arrangement can provide reliable shut-off when correctly selected for the process conditions.
Multiple Sealing Approaches
Plug valves can use different sealing approaches, including sleeved arrangements, depending on the application.
How to Select the Right Industrial Plug Valve
Proper valve selection helps achieve dependable sealing, operating performance and service life.
01. Process Medium
Identify the liquid, gas, slurry or other process medium and evaluate its chemical, abrasive and physical characteristics.
02. Pressure & Temperature
Confirm operating and design pressure and temperature before selecting the valve construction and sealing arrangement.
03. Sealing Method
Determine whether a sleeved, lubricated or another appropriate sealing arrangement suits the process requirements.
04. Flow Requirement
Consider flow rate, pressure drop, port configuration and whether the valve is intended primarily for isolation.
05. Operating Frequency
Evaluate how often the valve will cycle because operating frequency can influence the selection of plug and sealing components.
06. Manual or Automated
Choose the appropriate operating arrangement based on accessibility, process automation and required response time.
Industrial Plug Valve Frequently Asked Questions
What is an industrial plug valve?
An industrial plug valve is a quarter-turn rotary valve that uses a cylindrical or tapered plug with a flow passage to start, stop or control process flow.
How does a plug valve work?
The plug rotates inside the valve body. When its internal port aligns with the pipeline, flow can pass. Rotating the plug away from the aligned position blocks the flow path.
What is a sleeved plug valve?
A sleeved plug valve uses a sleeve around the plug as part of the sealing arrangement. The sleeve creates a controlled interface between the rotating plug and valve body.
Where are plug valves used?
Plug valves can be used in selected oil and gas, chemical, petrochemical, water and wastewater, mining, power and industrial process applications.
Can plug valves be automated?
Yes. Because plug valves use rotary operation, suitable configurations can be equipped with compatible actuators for automated process operation.
How do I select the correct plug valve?
Selection should consider process medium, pressure, temperature, flow conditions, sealing arrangement, operating frequency, connection requirements and automation needs.
