Pneumatic Actuated Valve

Pneumatic actuated valves use compressed air to operate valves for automated opening, closing or positioning. As a Pneumatic Actuated Valve supplier In Africa, African Valve manufactures and supplies pneumatic valve configurations for automated isolation, flow regulation and process applications. Pneumatic actuation is available with diaphragm or piston actuators and can be configured for mining, mineral processing, oil & gas, petrochemical, power generation, water and wastewater treatment, chemical processing and industrial applications.

Pneumatic Actuated Valve Features

• Automatic Operation - Uses compressed air for automated valve movement.
• Fast Actuation - Provides responsive operation for automated systems.
• On-Off Operation - Enables automatic valve opening and closing.
• Modulating Operation - Supports continuous positioning where required.
• Spring-Return Options - Provides a defined fail position when configured with a return spring.
• Double-Acting Options - Uses pneumatic pressure for both directions of movement.
• Positioner Compatibility - Supports accurate positioning in modulating applications.
• Application-Specific Selection - Valve, actuator and accessories are selected according to service conditions.
