ON-OFF Butterfly Valve

When a large pipeline needs dependable electrical isolation without adding unnecessary bulk to the piping arrangement, an ON-OFF Butterfly Valve offers a practical quarter-turn solution. The SVI Make configuration described here combines a 300 mm valve size with an electric actuator, cast iron construction and an EPDM seat for automated opening and closing. Designed for industrial piping requirements, it provides a convenient alternative to manually operated isolation at the valve location.

300 mm Automation for Straightforward Isolation

This 12-inch ON-OFF Butterfly Valve operates by rotating its disc through approximately 90 degrees. In the open position, the disc moves into alignment with the pipeline to permit flow; in the closed position, it works against the EPDM seat to establish shutoff. The electric actuator supplies the rotational movement, allowing the valve to be operated from a suitable electrical control arrangement.

The configuration is particularly suited to applications where the primary requirement is defined open or closed operation rather than continuous throttling. Its wafer-end construction also provides a compact installation arrangement between compatible pipeline flanges.

Technical Specifications

Important Construction Features

• Electric actuation: Provides automated quarter-turn movement for ON/OFF operation.
• Cast iron body: Offers a robust valve-body configuration for suitable industrial services.
• EPDM seat: Provides the specified sealing interface between the disc and valve body.
• Wafer-end design: Supports a compact installation arrangement with compatible flanges.
• PN16 pressure rating: Defines the specified pressure class for the valve configuration.
• API 609 face-to-face: Provides a dimensional reference for compatible installation planning.

How the Electric Operation Works

The actuator converts electrical energy into rotary motion and transfers torque through the valve shaft to the disc. A suitable control signal can command the actuator toward the open or closed position. Depending on the actuator configuration, position feedback or limit-switch functionality can be incorporated to indicate the valve's operating status to an automation system.

This arrangement is useful where valves are positioned in locations that are difficult to access regularly or where synchronized operation is required across an industrial piping network. Proper actuator sizing should be established according to valve torque, operating conditions and the intended duty cycle.

Industrial Installation Perspective

The 300 mm ON-OFF Butterfly Valve can be considered for suitable water, utility and industrial process piping where electrically operated isolation is required. Butterfly construction keeps the valve relatively compact while the quarter-turn operating principle allows rapid transition between defined operating positions.
