Refrigeration service maintenance accessory for four-way air conditioning reversing valve (1P)

General Description

The four-way diverter valve refrigeration service maintenance accessory is designed for reliable operation under low differential pressure conditions. It features low pressure drop and excellent sealing, making it an ideal choice for heat pump-type systems, such as central, unitized, and individual air conditioners. Its electromagnetic coil, made of thermosetting plastic, offers resistance to water and lightning, as well as high-performance insulation. This product is also lightweight, energy-efficient, and quiet while offering good vibration resistance.

Installation

Before proceeding with the installation of the four-way valve For four-way valve conversions, it is important to follow certain steps to ensure optimal operation:

• Use a plastic cap to block the four nozzles to prevent impurities from entering the valve.
• Check the position of the four-way valve slider inside the main valve body; it should be on the left.
• Wrap the four-way valve in a damp cloth before desoldering.
• Pay attention to the flame direction when soldering to avoid overheating the valve body.
• Use a silver-containing brazing filler metal to ensure weld quality.
• If possible, use nitrogen-filled shielding during soldering to reduce oxide skin formation.

Application

This product is used to convert refrigeration and heating systems by changing the refrigerant flow path. It is essential to purge the oxide skin inside the four-way valve with nitrogen after welding and to take care to avoid moisture during cooling.
