Air Conditioner Four Way Reversing Valve For Heat Pump Refrigeration
The 4-way valves are used in reversible applications such as heat pumps or reversible air conditioning units and chillers.
The 4-way valve allows an inversion of the refrigeration cycle, changing from cooling mode in summer to heating mode in winter.
The 4-way valve slider is shifted by changes in differential pressure in the valve which is actuated by the pilot solenoid valve. The valve slider is specially designed to prevent incomplete changeover and movement with minimum pressure differential.
