The Motorised Valve Controller is used for gas fired/oil fired furnace valves. This controller takes input either from thermocouple or pressure/flow transmitter, and according to set point gives signal to the motorized valve to open or close the valve. The controller uses PID algorithm and has facilities like self-tuning and auto-tuning, which sets user without worrying about the PID parameter setting. With optional feature of extra auxiliary input one can have close loop control also to get better control.
Gas/oil fired furnaces/boilers, flow control, etc. Controllers for cascade control/ratio control, and temperature programmers are also available.
