Product overview

JQ-818 series switch type electric valve is composed of JQ-818 series valve driver and JQ-818 series copper valve. It is used to control the opening or closing of cold water or hot water air conditioning series pipes to control room temperature. The driver is driven by a unidirectional hysteresis synchronous motor and the valve spring returns. The valve is normally closed when it does not work. When it needs to work, the temperature controller provides an opening signal to connect the electric valve with AC power, open the valve, and the chilled water or hot water enters the fan coil to provide air conditioning or heating for the room; When the room temperature reaches the set value of the temperature controller, the temperature controller will power off the electric valve, and the return spring will close the valve, so as to cut off the water flow into the fan coil. By closing and opening the valve, the room temperature is always kept within the temperature range set by the thermostat. The driver of jq-818 series electric valve is connected with the valve body by screw sleeve. The driver can be installed after the valve is installed. It can be assembled on site, and the wiring is flexible and convenient. The plane design of the driver can be installed close to the wall with small space. The product is reliable and durable, with low working noise, and can work reliably in the high temperature environment often found in the concealed fan coil unit.
