PRODUCT DETAILS
The Q641F Pneumatic Actuated Flanged Floating Ball Valve is designed for fast and reliable automated shut-off in natural gas, LPG, and compatible industrial pipeline systems.
Its two-piece flanged body provides a strong and removable pipeline connection, while the floating ball design uses line pressure to push the ball against the downstream seat for dependable soft-seated isolation.
The pneumatic actuator provides rapid 90-degree quarter-turn operation. Double-acting and spring-return configurations are available, including fail-close and fail-open options for emergency shut-off and process safety applications.
