Regulating valve is a fluid control device, it can control fluid flow, pressure, temperature and other parameters, in order to achieve the purpose of regulating fluid flow characteristics. It is composed of a piston or ball spool, in which there is a manual or electric mechanism with adjustment function, it can control the position of the piston or ball spool, so as to change the pressure and flow rate in the valve, so as to adjust the flow characteristics of the fluid.
The main function of the regulating valve is to adjust the flow rate, pressure and temperature, so that the fluid flow characteristics are more stable, so as to improve the efficiency of the fluid. It can regulate the flow of fluid to keep it at a low level, thus saving energy; The pressure of the fluid can also be adjusted to keep it at a low level, thus reducing noise in the piping system; The temperature of the fluid can also be adjusted to keep it at a low level, thus preventing condensation in the piping system, etc.
