Worm Gear Concentric Flanged Butterfly Valve Description
The Gear Worm Concentric Flanged Butterfly Valve represents the pinnacle of butterfly valve engineering and technology. It utilizes a rugged worm gear actuator to enable precise flow control and reliable shutoff across a wide range of operating conditions.
The concentric body design provides symmetrical flow characteristics for optimal regulation and efficiency. Flanged end connections allow easy, secure installation and provide accessibility for inspection and maintenance.
The wear-resistant valve seat is customized to handle the intended service fluid. The disc edge is polished to mate tightly with the seat for leak-proof shutoff when closed. The disc is engineered in materials suitable for the process requirements.
The self-locking worm gear drive gives accurate positioning of the disc for superb throttling capability. It requires less operating torque than other actuation methods. The compact gearbox is designed for high durability, strength, and cycle life.
Offering reliable performance, versatile application range, energy savings, and low maintenance needs, the Gear Worm Concentric Flanged Butterfly Valve is the premier choice for on/off and control applications across water, chemical, petrochemical, and other industries.
