product description:
The electric ball valve consists of a valve body and a driver. It has the advantages of simple structure, reliable operation, strong fluid passing ability and energy saving. It can be widely used in heating, central air conditioning, solar hot water system, water treatment system cold and hot water on-off control.
technical parameter:
Driving voltage: AC220V±10%, 50/60Hz
Power consumption: 5VA (only when the valve is opened and closed)
Action time:≧15s
Nominal pressure: 1.6Mpa
Applicable medium: cold, hot water or low pressure steam (≦0.4Mpa)
Medium temperature: 1-90℃
Ambient temperature: 0-65℃
Connection method: 7G inner pipe thread fan coil electric ball valve built-in contact switch, the motor is not energized after the valve opening and closing process is completed, so the life is long, energy saving, and particularly safe, the valve body is separated from the driver, which can be quickly disassembled, valve body structure Unique, large flow, no slag blocking, and large closing pressure difference; the actuator adopts an eccentric structure, which can be installed after the equipment and pipeline are installed. It is easy to disassemble and install, which is beneficial to improve the installation efficiency. , 3/4", 1" three types of valve bodies. It is used in the central air-conditioning fan coil, the on-off of cold water/hot water in solar energy systems and the on-off of other fluid systems.
Structural features
1. Brass forging valve body, stainless steel rod and spring, small size and corrosion resistance
2. The valve core structure is optimized, and the allowable pressure difference is large without reducing the Ky value.
3. The driver is separated from the valve body and can be quickly disassembled.
4. The driver has a manual operating lever for system debugging and maintenance.
line, the black line is the common line. Three lines and two controls, two live lines and one zero line (one valve opening line plus one closing valve line plus common zero line) control the valve. The blue line is the closing valve
