Product Name:
Pneumatic Actuated Lug Type Butterfly Valve

Description:
Our Pneumatic Lug Type Butterfly Valve is a high-performance, automation-ready flow control solution designed for precise and efficient operation in industrial fluid handling systems. Engineered with a robust lug-type body and double-acting or single-acting pneumatic actuator, this valve ensures reliable on/off or modulating control across a wide range of process applications.

The lug-style design allows for easy installation between flanges and supports dead-end service, making it ideal for systems requiring sectional isolation. This valve is suitable for use with compressed air automation systems and delivers quick response time, minimal air consumption, and high durability.
