This Belimo valve is a precision-engineered device designed for fluid control in various applications. It features a 1/2 inch National Pipe Thread (NPT) size, ensuring compatibility with standard pipe fittings. The valve operates at a power of 2 Watts (2W), providing efficient performance with minimal energy consumption. With a flow coefficient (Cv) of 2.5, it offers optimal flow rates for many applications. The valve operates on a voltage of 120 Volts (120V), making it suitable for use in most residential and commercial settings. It has a normally closed (N/C) configuration, meaning the valve is closed when the power is off, providing safety and preventing unwanted fluid flow. Additionally, it comes with an actuator (w/Au), which automates the opening and closing of the valve, enhancing its functionality and ease of use.
