(1)Automatic regulating valve
The regulating valve relies on the ability of the regulated medium (liquid, air, steam, natural gas) itself to realize the automatic adjustment of temperature, pressure and flow of the medium.
(2)Driving regulator
A regulator operated by hand, electric, air or hydraulic pressure.
(3)Pneumatic regulating valve
Driven by compressed air, the actuator regulates the area of the fluid path by the controller's signal to change the fluid flow.
(4)Electric regulating valve
Electrically powered actuators that regulate the area of the fluid path by a controlled signal to change the fluid flow.
(5)Self-operated temperature regulating valve
The sensitivity of the special liquid to the temperature in the sensor is used to push the spool to do linear change through the transfer of the capillary, so as to control the opening of the valve with the change of temperature and control the flow of the medium.
