Class 900 LB Butterfly Valve

A Class 900 LB Butterfly Valve is a shut-off valve designed to handle high-pressure applications, roughly equivalent to PN150. It features a relatively simple construction, consisting of a disc that blocks the valve bore in the closed position and allows flow when turned to the open position. With just a quarter turn, it transitions from fully open to fully closed or vice versa, enabling quick opening and closure. These valves find extensive use across various industries, including water supply, wastewater treatment, fire protection, gas supply, chemical and oil industries, fuel handling systems, and power generation.
