Alco Controls 240RA 9T7M Refrigerant Solenoid Valve

Alco Controls 240RA 9T7M Refrigerant Solenoid Valve is a compact two‑way, normally closed diaphragm valve designed for refrigerant service in HVAC and commercial refrigeration. It features 7/8 in ODF inlet and outlet connections and a 9/16 in internal port, with a maximum working pressure of 500 psi, making it suitable for demanding refrigerant circuits. This coilless variant ships without an electrical coil, allowing you to pair it with a compatible coil kit (sold separately) to match your control voltage and installation. The suffix M indicates a manual stem option, providing a mechanical override if electrical actuation is unavailable. The 240RA series is specified for liquid and discharge gas refrigerant service, commonly used to control flow in refrigeration loops where reliable shutoff and compact form factor are required. As a two‑port, normally closed valve, installation is straightforward in line applications on liquid or gas refrigerant paths, with a diaphragm body designed for leak‑tight operation under typical system conditions. This configuration—240RA 9T7M with 7/8 in ODF connections—offers a compact footprint for retrofit projects or new installations where a standard 240RA valve is appropriate, and coil assemblies from Alco/Emerson can be paired to suit the control circuit. When selecting a valve, verify your coil voltage and the refrigerant type and pressure differentials to ensure reliable actuation and shutoff.
