Yihai LCD room thermostat series are temperature controller which use advanced electric elements to accuracy control on/off, modulating valves, and 3-speed fan coil unit, to achieve room temperature same as setting temperature. The products can connect with BAS via Modbus and Rs485, widely used in 2-pipe and 4-pipe fan coil system, like hotel, hospital.
Yihai motorized zone valve is used to control the flow of chilled or hot water in residential, commercial HVAC system, such as fan coil unit, terminal reheat coils and water treatment industrial. Our valves are drove by motor, through gear assemble to push or rotate valve core to open or close the valve.
Yihai electric ball valve series feature on/off, floating, modulating control, size from DN15-DN150 with forged brass threaded valve body or iron cast flanged valve body. Our valves are drove by bi-directional motor and gear assemble, when valve closed or opened, the power will off, this will save energy and extend the product life.
Yihai electric control valve assemble from 1000N to 20000N force actuator with manual lever and valve size from DN20 to DN600, on/off and modulating, which widely used in air conditioning, refrigeration, heating and building automation system, can adjust the water flow precision, achieved goal to control temperature, humidity, pressure and energy saving.
Yh3x2 / yh7x2 series drivers are used together with electric control valves to realize floating point control of valves. Through the adjustment and control of the valve body, the medium flow in the system pipeline can be adjusted, so as to achieve the purpose of constant temperature, pressure, humidity and other parameters control. It is widely used in air conditioning, heating and other building automation systems.
Yiahi control & sensor series includes water flow switch, duct and water sensor and so on to detect the flow, temperature to control valves close and open.
Yihai hydraulic balance valve series include static balance valve and dynamic balance valve, which can adjust the flow accuracy.
Yihai HVAC control valve series include some general valves, like gate valve, brass filter, air conditioning bellows, to connect and control terminal valves or devices.
