Plug Valves
4 Way Multi Port Plug Valve
Four-port plug valve for flow reversal and multi-line switching duties.

Overview
A 4-way plug valve is a specialized industrial valve designed with four ports arranged in a specific configuration: one inlet, one outlet, and two diverter ports.
Key features
- Multi-Port Configuration: 4-way plug valves have four ports (inlet, outlet, and two diverting ports) arranged in a specific configuration that allows for multiple flow path options. The plug inside the valve can be rotated to divert flow between the ports as needed.
- Rotating Plug Mechanism: Similar to standard plug valves, 4-way plug valves feature a cylindrical or tapered plug that rotates within the valve body. This rotation controls the direction of flow and determines which ports are connected.
- Durable Construction: They are typically constructed from robust materials such as stainless steel, carbon steel, or other alloys, depending on the application requirements. This ensures durability and resistance to wear and corrosion.
- Lined Versions Available: Like standard plug valves, 4-way plug valves can also be lined with materials such as PTFE (polytetrafluoroethylene) or other fluoropolymers to enhance chemical resistance and prevent corrosion.
- Actuator Compatibility: Many 4-way plug valves are designed to be compatible with actuators, allowing for remote or automated operation. This enhances control precision and enables integration into automated process systems.
