Wafer High Performance Butterfly Valves, 316 Body, Worm Gear Operator
APPLICATION:
Goldtop Valves is a professional manufacturer of soft seat, metal seat and fire-safe high performance butterfly valves, our valves are with 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 exceptionally long and trouble-free service life, reducing 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.
