product overview

Gv4303Series electric valves are used to control the opening or closing of central air conditioning and heating system pipelines, achieving the purpose of controlling room temperature. The control valve is driven by a unidirectional hysteresis synchronous motor with a spring reset. When the valve is not working, it is in a normally closed state. When it needs to work, the temperature controller provides a valve opening signal to connect the electric valve to the AC power supply and activate it. When the valve is opened, chilled water or hot water enters the fan coil unit to provide air conditioning or heating for the room; When the room temperature reaches the set value of the thermostat, the thermostat cuts off the power to 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 GV4303 series electric valve can be optionally equipped with an auxiliary switch for controlling other equipment; And different connection forms and applicable voltages can be selected to meet different needs.
The GV4303 series electric valve is flexible in operation, reliable and durable, with low working noise, and can withstand high temperature and high humidity environments commonly found in concealed fan coil units.

Installation instructions

1The installation of normally closed two-way valves and diversion three-way valves is shown in Figure 1, Figure 2, and Figure 3.
For high-rise buildings, pressure reducing valves should be installed on the bottom branch pipes.
2. The motor casing should prevent water from seeping in. When the valve is installed in a horizontal pipeline, the angle between the installation position and the vertical plane should not exceed 85 ℃ (see Figure 4).
3. When the valve is installed on a vertical pipeline, the motor casing must prevent dripping water from seeping in.
4. Manual operating lever: When the manual lever is slowly moved in the direction of the arrow and pressed into the notch, the valve is in a normally open state. Whenever the current * passes through the electric valve, the manual lever will be reset to the automatic position.
