The term four-way valve and hydraulic valve is a control valve with four oil ports.Four-way valve is the indispensable parts in refrigeration equipment, electromagnetic valve coil are in a state of power failure, the guide slide valve in the compression spring driven by moving to the left, on the right side of the high pressure gas entering

The capillary into the right side piston cavity, on the other hand, the left side of the piston chamber gas expelled, piston at both ends of the pressure difference, therefore, and the main valve piston moving to the left, the exhaust pipe and separate-bodied air-conditioners are interlinked, the other two be inherited.

Form a refrigeration cycle at the solenoid coil, price lead capsule accumulator valve under the effects of the magnetic force in the electromagnetic coil to overcome the compression spring tension to the right, after the high pressure gas into the capillary into the left side piston cavity, on the other hand, the right end of piston chamber of the gas discharge, due to the existence pressure difference on both ends of the piston, the piston and the main valve to the right, the exhaust pipe and take over the house, the other two root canal by, hydraulic accumulator manufacturer to form the heating cycle.
