‘SANLAN' Solenoid Valve Type APS-1 is a specially designed 3-way capacity control solenoid valve for compressor. It is applicable for working media of refrigerant oil and fluorinated refrigerants.


The valve has three ports, with ¼" SAE external threading connections. These ports are marked as OIL IN, UNL and SUMP respectively.

OIL IN - Oil Inlet port, which should be connected to the compressor oil pump discharge, is at the bottom of the valve. This is normally closed port.
UNL - UNL is the middle port. Unloader power element is connected to this port. When the valve gets energized, oil pressure coming through the OIL IN port, is given to the power element through this port, which in turn loads the cylinder.
SUMP - Sump port should be connected to the oil sump. When the valve gets de-energized, remaining oil from the unloader power element will be pushed back into the oil sump through this port.
