AV-1HLW-316 Lugged High Performance Butterfly Valves, 316 Body, Worm Gear Operator

Lugged High-Performance Butterfly Valves APPLICATION:

Adamant Valves is a professional manufacturer of soft seat, metal seat, and fire-safe high-performance butterfly valves, our valves are with a double offset design, reach bi-directional bubble tight shutoff (zero leakage) by the use of a patented seat. Our High-Performance Butterfly Valves are designed for critical applications in food and beverage processing, chemical industries, petrochemical industries, power plants, district heating. They provide an exceptionally long and trouble-free service life, reducing the total cost of ownership. Adamant valves are rigorously tested to meet demanding industry performance requirements. High-Performance Butterfly Valves are designed for shutoff and throttling control of liquids and gas. The dynamic PTFE/RTFE seat provides bubble-tight shutoff in both directions.  The unique disc design provides lower torque and longer cycle life.
