Parker Fluid Control 73218BN4UN00N0C148 1/2" 2-Way N/C Solenoid Valve 120V

The Parker Fluid Control 73218BN4UN00N0C148 1/2-inch 2-Way Normally Closed Solenoid Valve is an electrically operated valve used to control the flow of compatible fluid through a piping circuit. When activated, the solenoid moves the internal valve mechanism to permit flow, while the normally closed design keeps the passage shut when power is removed in HVAC systems. It can be used in fluid control circuits where automatic on-off regulation is required. The valve is installed inline with the piping connections and operates through an electrical control signal, allowing connected equipment to regulate fluid movement during designated operating cycles.
