TECHNICAL DATA SHEET
Hydraulic Actuated Concentric Butterfly Valve
Stainless Steel Body · Rubber Seated
- PRODUCT DESCRIPTION
The Hydraulic Actuated Concentric Butterfly Valve is a resilient-seated quarter-turn rotary valve designed for precise flow control and positive shut-off in demanding industrial and municipal applications. Featuring a concentric disc design with a stainless steel body and elastomer seat, this valve provides bubble-tight sealing, low pressure drop, and reliable performance across a wide range of media including water, oil, gas, and corrosive fluids.
The hydraulic actuator delivers substantial torque for smooth operation against significant line pressures, making this valve ideal for high-pressure automated systems requiring remote operation and SCADA integration.
