A Pneumatic Plug Valve is a type of quarter-turn valve that uses compressed air to control the flow of fluids in a piping system. It features a cylindrical or conical plug with a through-hole that can be rotated to align with the flow path (open position) or perpendicular to it (closed position). The valve is actuated by a pneumatic actuator, which provides automated and precise control. Pneumatic plug valves are widely used in industries such as oil and gas, chemical processing, water treatment, and food and beverage, where automation, reliability, and quick operation are essential.
Key Specifications:
- Widely used in industries such as petroleum, chemical industry, pharmacy, chemical fertilizer, power and industry
- Nominal pressure: class 150 to 900lb
- PN: 1.0 to 16.0
