The design of HS4D provides three positions for the valve: fully closed, partially open (10 to 15 percent stroke) and fully open. The two-step solenoid valves are normally closed and will revert to the closed position in the event of a power failure. The valve can be opened via the manual opening stem for pump-out during maintenance. The flange-bodied valve can be used anywhere a traditional refrigerant solenoid valve is employed.
