Room Air Conditioner Valve

This 1/4" water line service valve replaces a worn or leaking refrigerator water valve to restore controlled water flow to the dispenser or icemaker. It provides a direct, plumbing-style connection for the appliance water line. What it does

• Controls water flow through a 1/4" appliance water line to the dispenser or icemaker
• Stops or allows water to the ice maker and dispenser when opening/closing the valve
• Helps stop leaks or drips caused by a damaged or corroded valve
• Can eliminate water delivery interruptions when the valve fails

• One 1/4" water line service valve

• Turn off the home's water supply and unplug the appliance before starting
• Use appropriate wrenches and fittings; avoid overtightening to prevent damage
• Inspect tubing and fittings for wear; replace seals or tubing as needed
• After installation, restore water and power, then check carefully for leaks

This 4-way reversing valve controls refrigerant flow direction in refrigeration and heat-pump systems to enable switching between cooling and heating modes. It restores correct refrigerant routing so the system can perform as intended. What it does:

• Directs refrigerant flow between evaporator and condenser to switch system mode
• Allows a heat-pump system to reverse cycle for heating or cooling
• A failing valve can cause loss of heating or cooling, abnormal cycling, or reduced system performance
• Valve must form a sealed refrigerant path; leaks or stuck spool will impair operation

• One 4-way reversing valve

• Disconnect power and follow lockout/tagout before service
• Refrigerant handling (evacuation, brazing, charging) must be done by a qualified HVAC technician
• Inspect and replace associated gaskets, fittings, and access components as needed; pressure-test and vacuum system after installation
• Follow OEM service instructions and local refrigerant regulations
