3 Way Plug Valve

A three-way plug valve uses a specially configured plug passage to divert, distribute or combine flow between three connected ports. African Valve is a 3 Way Plug Valve Suppliers in South Africa supplying configurations for process systems where flow routing needs to be changed through a single valve assembly.

Key Features

• Three-Port Arrangement: Connects three process lines through one valve body.

• L-Port / T-Port: The plug passage determines the available flow paths.

• Flow Diversion: Routes flow between selected ports.

• Flow Distribution: Directs a common inlet towards selected outlets.

• Quarter-Turn Operation: Changes the flow path through plug rotation.

• Manual / Actuated: Available with lever, gearbox or actuator operation.

Applications in South Africa

Three-way plug valves are relevant to mineral-processing plants, mining circuits, chemical facilities, water-treatment systems and industrial process lines, where flow must be diverted, distributed or combined between connected pipelines.

Standards

Applicable requirements may include API 599, ASME B16.34, ASME B16.5, ASME B16.10 and API 598, according to the selected valve construction and project specification.

Engineering Note: The L-port or T-port must be selected according to the customer's flow schematic. Standard three-way plug valves should not automatically be assumed to provide bubble-tight isolation across every unselected port simultaneously; this depends on the plug and sealing arrangement.
