Overview
The SEV2000 split type electric valve series consists of SE20 series valve drivers and VE2 and VE3 series copper valves. Used to control the opening or closing of cold or hot water air conditioning system pipelines, achieving the purpose of controlling room temperature, and can adjust the Kv value. The driver is driven by a unidirectional hysteresis synchronous motor, and the valve spring is reset. When the valve is not working, it is in a normally closed state. When it needs to work, the temperature controller provides an 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 control range.

Installation Steps

Characteristics
The SEV2000 series split type electric valve has two forms: normally closed two-way and mixed three-way. It is divided into three categories according to the valve port connection size: DN15, DN20, DN25, and six specifications according to its flow form and flow characteristics.  

The driver and valve body of the SEV2000 series split type electric valve are connected by a screw sleeve, which can be installed after the valve is installed and assembled on site. The wiring is flexible and convenient. The planar design of the driver can be installed close to the wall, occupying less space. The product is reliable and durable, with low working noise, and can work reliably in high-temperature environments commonly found in concealed fan coil units.
