Valves
Plug Valves
Our plug valves give fast, low-torque, quarter-turn on-off control in a compact one-piece body. The straight-through flow path keeps pressure drop low, the valve can throttle forward flow, and a replaceable plug assembly keeps maintenance simple. A practical choice for instrument air, sampling, drain and vent lines.
Pressure rating
Up to 3,000 psi (206 bar)
Materials
SS 316, brass
Sizes
1/8" to 1/2"; 6 to 12 mm
End connections
TEQLOK™ tube ends, NPT, BSPT
Key features
Quarter-turn, low-torque operation with positive shut-off of forward flow
Straight-through flow path for low pressure drop, with forward-flow throttling
One-piece body with a replaceable plug and O-ring stem seal, easy to clean and maintain
