Friedrich 25018305 4-Way Reversing Valve without Coil

The Friedrich 25018305 is a genuine OEM 4-way reversing valve manufactured by Dunan, designed for use in Friedrich heat pump and air conditioning systems. This reversing valve efficiently directs refrigerant flow in air conditioners and heat pumps for optimal heating and cooling performance.

The reversing valve is compatible with several Friedrich HVAC units including KUHL, Wallmaster and small chassis VTAC units. This is a reversing valve without coil, featuring 4-way operation with 3/8" x 1/4" connections.

Key Features:

• Genuine Friedrich OEM replacement part
• Dunan DSF series 4-way reversing valve body
• Sold without solenoid coil (coil purchased separately)
• 3/8" x 1/4" connection fittings
• Controls refrigerant flow direction for heating/cooling mode switching
• Durable brass construction for long service life

The DSF series 4-way reversing valve changes the flow path of refrigerants by controlling the pilot valve to switch the mode between cooling and heating, with reliable instantaneous changeover under minimum pressure differential. This component is essential for proper heat pump operation, enabling the system to reverse refrigerant flow for both heating and cooling functions.
