Resilient Seated Butterfly Valve

Designed for dependable isolation in water and general industrial services, a Resilient Seated Butterfly Valve Manufacturer in Canada supplies valves with a compact construction and tight shut-off. The resilient elastomer seat seals against the disc to minimise leakage and provides smooth operation with relatively low operating torque.

Resilient seated butterfly valves are widely used in water distribution, wastewater treatment, irrigation, fire protection and industrial utility systems where reliable flow isolation is required.

Features

• Resilient elastomer seat for tight shut-off
• Concentric or zero-offset disc design
• Compact and lightweight construction
• Low operating torque
• Wafer, lug and double-flanged configurations
• Manual, gear, pneumatic and electric actuation
• Suitable for water and general utility services
• Bidirectional shut-off
