Pneumatic Actuated Butterfly Valve

Automated flow control is essential in industrial pipelines that handle water, gases, and compatible process fluids. Valves Only Canada supplies pneumatic actuated butterfly valve in Canada for industrial facilities requiring efficient flow regulation, dependable shut-off, and integration with automated control systems. These valves combine a butterfly valve with a pneumatic actuator powered by compressed air. The actuator rotates the valve disc approximately 90 degrees to open or close the flow passage. The valve body, disc, seat, stem, and actuator are selected according to operating pressure, temperature, media compatibility, and control requirements. 

Features 

• Compressed-air-powered actuator for automated valve operation. 
• Quarter-turn design for rapid opening and closing. 
• Compact construction with space-efficient installation. 
• Suitable for on/off service and throttling when the valve is designed for that purpose. 
• Double-acting or spring-return actuator options. 
• Remote operation through compatible PLC and DCS systems. 
• Wafer, lug, or flanged body configurations, depending on the model. 
• Resilient-seated or high-performance designs for different operating conditions. 
• Body and disc materials selected for process media compatibility. 
• Suitable for water, air, gases, and compatible industrial process fluids.

Standards and Testing 

Pneumatic actuated butterfly valves are manufactured, inspected, and tested according to applicable valve design standards and project requirements. API 609 covers butterfly valves within its scope, including relevant design categories. ASME B16.34 addresses valve pressure-temperature ratings, materials, and related design requirements for applicable valves. ASME B16.5 covers pipe flanges and flanged fittings within its size and pressure-class scope. API 598 provides inspection and pressure-testing requirements for applicable valve types. For fire-safe applications, API 607 may apply to qualifying quarter-turn valves, subject to its scope and requirements.
