350MM Pneumatic Actuator Butterfly Valves

For large-diameter pipelines where dependable automated isolation is required, actuator sizing and valve construction become especially important. Our 350MM Pneumatic Actuator Butterfly Valve is configured with a double-acting pneumatic actuator, cast iron body, wafer-end connection, EPDM seat, and PN16 pressure rating. Manufactured by Shiv Valves Industries in Ahmedabad, Gujarat, this valve is intended for industrial flow-control systems requiring repeatable quarter-turn operation through compressed air.

Large-Diameter Flow Control with Pneumatic Operation

The 350 mm valve combines a butterfly disc mechanism with a double-acting pneumatic actuator. Compressed air drives the actuator in both directions, producing the torque required to move the disc between open and closed positions. This arrangement reduces the need for manual intervention and is well suited to systems where the valve needs to be operated repeatedly from an automated control arrangement.

The wafer-end configuration provides a compact valve format for installation between compatible pipeline flanges. The EPDM seat forms the resilient sealing interface, while the cast iron body provides the principal structural housing for the valve assembly.

How the Double-Acting Arrangement Works

1. Compressed air is supplied to the pneumatic actuator.
2. The actuator converts air pressure into rotary mechanical movement.
3. The generated torque is transferred through the valve stem to the butterfly disc.
4. The disc rotates through the quarter-turn operating range to establish the required open or closed position.
5. Air supplied for the opposite direction drives the actuator back, allowing controlled closing or opening.

Because the supplied configuration is double acting, pneumatic pressure is used for both directions of actuator movement. This makes the arrangement particularly relevant where consistent opening and closing cycles are required.

EPDM Seating and PN16 Construction

The EPDM seat provides the specified resilient seating arrangement for the valve. Seat compatibility should be evaluated against the actual process medium and operating temperature before installation. With a PN16 pressure rating, the valve should likewise be selected and operated within the applicable pressure and service limits.
