Introduction
An ANSI Plug Valve is a rotary on-off valve that controls, stops, or diverts fluid flow by rotating a plug with a rectangular or tapered hole inside the valve body.

Features
ANSI Standard Design - Manufactured to conform with ANSI/ASME dimensional and pressure requirements for reliable industrial pipeline compatibility.
Quarter-Turn Rotary Operation - Smooth quarter-turn plug rotation enables fast open/close action with low operating torque and simple control.
High Shut-off Capability - Cylindrical or tapered plug and port design provide tight shut-off and minimal leakage in fully closed positions.
Versatile Flow Options - Straight-through, multiport (3-way/4-way), or diverting configurations allow flexibility in flow routing and process control.
Lubricated / Unlubricated Designs - Available with internal lubrication for ease of operation under wide pressure ranges or with sleeves/seals for low maintenance.
Low Flow Resistance - Plug valves offer minimal obstruction and reduced pressure drop when fully open.
