This Belimo actuator valve 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 valve operates on a 24-volt power supply, making it suitable for low voltage systems. It has a Normally Closed (NC) configuration, meaning the valve stays closed until an electrical signal triggers it to open. With a flow coefficient (Cv) of 5.0, this valve can handle significant volumes of fluid or gas under normal operating conditions. The device also boasts a closing force of 25 pounds, ensuring secure closure and preventing unwanted leakage.
