This Belimo valve actuator is a precision-engineered device designed for regulating the flow of fluids or gases in a pipeline. It features a 3/4" National Pipe Thread (NPT) connection, which is a standard size for many industrial and commercial applications. The actuator operates on a 24-volt power supply, ensuring reliable performance even in low-voltage situations. It has a Normally Open (NO) configuration, meaning the valve stays open when the power supply is off and closes when it's on. With a flow coefficient (Cv) of 3.5, this actuator can handle significant volumes of fluid or gas without compromising its efficiency. The closing force of this actuator is rated at 30 pounds, providing ample strength to secure the valve in its closed position.
