 Features and uses 
 SM-C dynamic balance of electric control valve, the pressure is to change the use of media self-control is power proportional integral control function of a two-spool valve, widely used for heating and refrigeration and air conditioning and other non-corrosive media flow control valves, can also do power off valve. Before running a one-time adjustment, either to make the system a constant flow of flaring the required settings.
