YHY series differential pressure control driver
overview:
The YHY series drive is used in conjunction with the electric regulating valve to realize the floating-point control of the valve.Through the adjustment and control of the valve body, the adjustment function of the material flow in the pipeline of the system is realized, so as to achieve the purpose of controlling the parameters of the system such as constant temperature, constant pressure, and constant humidity. It is widely used in air conditioning, heating and other building automatic control systems.
Product features:
1.The actuator adopts die-cast aluminum bracket and ABS shell;
2.Flexible combination of valve body and actuator, which can adapt to the needs of different pressure differentials;
3.The actuator adopts synchronous motor and has a limited power-off protection function.Can produce a stable torque at a standstill so that the valve can be stationary in any position;
4.Forward and reverse control: forward and reverse can be set as needed to match different valve bodies.

Installation method and precautions:
1.Reserve enough space during installation for maintenance.
2.After the control valve is installed, the wiring should comply with the national electrical construction specifications, and the wiring should be in case of power failure.
3.The drive cannot be covered by thermal insulation materials to prevent the drive from dissipating heat unfavorably.
4.Vertical installation should be given priority. It can be installed tilted or horizontally on special occasions, but support is required when the volume, weight, and vibration are too large.
5.It is recommended to install manual valves at both ends of the fixed control valve for easy maintenance. During use, the screw and gear should be regularly maintained with butter for three to four months.
6.When the installation location of the regulating valve is not indicated on the design drawing, the regulating valve is generally installed on the loop water pipe.
