Danfoss HPA2 Actuator 4-Wire 230V - Replacement Motor

Keep your heating and cooling systems running efficiently with the Danfoss HPA2 Actuator. This 2-port, normally closed (N.C.) spring return valve actuator is a reliable solution for controlling fluid flow in both HVAC and industrial applications. Designed for safety and automation, the integrated spring return mechanism ensures the valve automatically reverts to its default closed position whenever power is removed. This 4-wire actuator is specifically engineered as a high-quality spare or replacement motor for 2-port zone valves. It is most commonly fitted onto the HPV22 22mm valve body, providing a seamless fit for your existing setup. With its built-in SPST (Single Pole Single Throw) auxiliary switch, you can easily signal or integrate the unit into your broader control systems for better monitoring and management. Whether you are performing routine maintenance or repairing a faulty valve, the Danfoss HPA2 offers a direct replacement option for several common models. It is compatible with Landis & Gyr SK2, Pegler Sunvic SZ1301/SZ2301, and Potterton PMV2 actuators, making it a versatile choice for various central heating system configurations.
