Technical Specifications
Key Features & Applications
Pneumatic Actuated Plug Valve Supplier in Nigeria, provides pneumatic actuated plug valves designed to combine the quarter-turn operation of plug valves with compressed-air actuation. These valves are suitable for oil & gas, petrochemical, chemical processing, water treatment, power generation, mining and general industrial applications.
Pneumatic plug valves can be configured with double-acting or spring-return actuators, solenoid valves, positioners, limit switches and air filter regulators for remote and automated operation. Actuated plug valves are available in flanged, threaded, socket-weld, sleeved and jacketed configurations depending on the application.
