Product Details

Product Overview
The VG4043 series electric valve is used to control the opening or closing of pipelines in central air conditioning systems and heating systems, achieving the purpose of controlling room temperature. The control valve is driven by a unidirectional magnetic hysteresis synchronous motor and returns with a spring. When the valve is not working, it is in a normally closed state. When it needs to work, the temperature controller provides an open valve signal to activate the electric valve by connecting it to AC power. When the valve is opened, chilled water or hot water enters the fan coil unit to provide cooling or heating for the room; When the room temperature reaches the set value of the temperature controller, the temperature controller de-energizes the electric valve, and the reset spring closes the valve, thereby cutting off the water flow into the fan coil. By closing and opening the valve, the room temperature is always maintained within the temperature range set by the thermostat.

The VG4043 series electric valve can be optionally equipped with an auxiliary switch for control of other equipment; And different connection forms and applicable voltages can be selected to meet different needs.

The VG4043 series electric valve is flexible in operation, reliable and durable, with low working noise, and can withstand high temperature and humidity environments that often occur in concealed fan coil units.
