Zhejiang Baolun central air conditioning electric two-way valve factory price

Zhejiang Baolun valve specializes in the production of central air conditioning fan coil electric two-way valve three-way valve q911f-16t electric ball valve electric valve miniature ball valve
1、 Product features: 1
It is used to control the opening or closing of cold water or hot water air conditioning system pipes to achieve the purpose of controlling room temperature
2
The driver is driven by a single-phase hysteresis synchronous motor, the tan spring of the valve is reset, and the valve is in a normally closed state when it is not working
When it needs to work, the thermostat provides an opening signal to make the electric two-way valve act by connecting the AC power supply
3
Open the valve, and the chilled water or hot water will enter 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 two-way valve, reset the tan spring to close the valve, so as to cut off the water flow into the fan coil
By closing and opening the valve, the room temperature will always be kept within the temperature range set by the temperature controller
4
The driver of the electric two-way valve is connected with the valve by thread, and the driver can be installed after the valve is installed
Field assembly, flexible and convenient wiring
The plane design of the driver can be installed close to the wall, with small space occupation, reliable and durable products, low working noise, and can work reliably in the high temperature and high humidity environment that often occurs in the concealed fan coil unit

2、 Product overview: the electric two-way valve is a Tao product for fan coil units of central air conditioning supplied by Zhang
It is composed of a driver and a valve body
The driver is driven by a synchronous motor and has the functions of Tan spring reset and manual valve opening lever operation
The valve body adopts piston structure
The electric two-way valve can be used with the temperature controller
The temperature controller controls the motor of the electric two-way valve to open or close the valve, so as to realize the on or off of cold water or hot water in the pipeline, and then supply air through the fan coil to realize the automatic adjustment of temperature

3、 Technical indicators: 1

4
Sealing material: Rubber (NBR)
5
Driver chassis: die cast aluminum alloy
6
Working medium: water
7
Medium temperature: ＜ 96 ℃

6、 Installation note: the motor housing should prevent water droplets from penetrating
When the electric two-way valve is installed in a horizontal pipeline, the included angle between the installation position and the plane shall not exceed 85°
When the valve is installed on the vertical pipe, the motor housing must prevent dripping water from penetrating
Move the manual lever slowly when you move it
When the manual lever moves slowly along the direction of the arrow and is pressed into the notch and stuck, the valve is in the normally open state
Whenever the current passes through the electric two-way valve for the first time, the manual lever will be set to the automatic position again
