Pulsating valve - Pulsating valve

Technical information Refrigeration Pulsating solenoid valves

Pulsating electromagnetic valves

Other electronically controlled alternative to the thermostatic expansion valve pulsating expansion valve. Unlike TXV, which closes or opens pressure, the solenoid valve is opened and closed electrically. In combination with the right electronic control system, the solenoid valve may pulse quickly, opening and closing in response to changes in the cooling load. This conceptual diagram illustrates the pulsing the solenoid valve is used by one manufacturer. Valve on the left shows the solenoid valve is closed when de-energized; view on the right shows the on condition. This type of valve is also performs the function of a solenoid valve in the liquid line, blocking the flow evaporator off cycle and in other moments when the refrigerant flow is not required.
