This Belimo valve actuator is a robust and reliable device designed for precise control of water or steam flow in various HVAC systems. It features a 3/4 inch National Pipe Thread (NPT) connection, ensuring compatibility with standard pipe fittings. The actuator operates on a 120-volt power supply, making it suitable for most commercial and industrial applications. With its Normally Closed (NC) configuration, the valve remains closed until it receives an electrical signal to open, providing enhanced safety and efficiency. The actuator boasts a high flow coefficient (Cv) of 5.0, indicating its ability to handle significant fluid flow rates without causing substantial pressure loss. Additionally, the unit can withstand up to 25 pounds of closing force, ensuring reliable operation even under challenging conditions.
