Application

This solenoid valve body is suited for use in refrigeration circuits requiring automatic liquid line shutoff, pump-down control, or multi-circuit evaporator management. The normally closed design ensures the refrigerant flow path is blocked whenever the coil is de-energized, providing an added layer of system protection during off cycles or power interruptions. The direct acting mechanism guarantees reliable operation across a wide range of operating pressures, making it a dependable choice for both new installations and service replacements.
