Emerson Flow Control (Alco) 030737 1/4" Ball Valve 204CD1/4B

The Emerson Flow Control (Alco) 030737 1/4" Solenoid Valve 204CD1/4B is a direct-acting, normally closed valve used to control refrigerant or fluid flow in small-diameter control lines. It operates by energising a coil that opens or closes the internal plunger, allowing or blocking flow depending on system. Identified as , this component is commonly used in refrigeration and air handling control circuits within HVAC systems where precise on/off fluid regulation is required. It supports controlled flow switching, assists in system sequencing, and helps maintain stable operation of connected components during startup, operation, and shutdown cycles.
