NEUMAX Pneumatic Actuated Butterfly Valve
A high-performance, automated quarter-turn butterfly valve with a concentric disc and lug-type body for straightforward dead-end installation. Driven by a pneumatic rotary actuator for fast, repeatable on-off or modulating flow control.
Product Description
NEUMAX Pneumatic Actuated Concentric Disc Lug Type Butterfly Valves are quarter-turn valves that use a centrally mounted disc within a resilient seat to give tight shut-off and reliable automated flow control. The lug-type body is tapped on both sides, allowing the valve to be installed at the end of a line or removed for maintenance without disturbing the rest of the piping. A pneumatic rotary (rack-and-pinion) actuator provides fast, repeatable 90° operation for automated on-off or throttling duty. Supplied by Pankaj Enterprises as a genuine NEUMAX product for process plants, utilities and industrial buyers across India.
- Concentric (centric) disc design for smooth, low-torque quarter-turn operation
- Lug-type body allows dead-end installation and easy in-line maintenance
- Pneumatic rack-and-pinion actuator gives fast, repeatable automated operation
- Resilient seat construction provides bubble-tight shut-off across the size range
Applications
- Water and wastewater treatment plant automation
