York S1-025-35388-002 Reversing Valve Els PW 17895 for the pressure-sensitive diaphragms to

for the pressure-sensitive diaphragms to trip accurately at their factory settings

The factory-installed 12A09 vent limiter (1/8" NPT) eliminates the need for external vent piping in indoor installations by limiting gas escapement in the event of a diaphragm rupture

which is sufficient for most 14 AWG to 2 AWG conductors used in small-to-medium motor applications

Using it with different refrigerants will result in incorrect superheat settings and potential liquid slugging or poor evaporator utilization

It features an SPST (Single-Pole Single-Throw) action that operates on an "Open High" logic

York S1-025-35388-002 Reversing Valve Els PW 17895 for the pressure-sensitive diaphragms toTesting and replacing a failed York S1 025 35388 002 Reversing Valve is a standard yet critical task for maintaining heat pump efficiency. This OEM York reversing valve is a 4 way pilot operated component designed to switch refrigerant flow between heating and cooling modes in R 410A and R 22 systems. It comes equipped with a 24V solenoid coil (50 60Hz), eliminating the need to source a separate actuator. When you encounter a heat pump stuck in one
