The Self-Regulating valve, also known as the self-operated control valve, is a regulating valve that relies on the pressure and temperature flowing through the medium inside the valve to act as an energy-driven valve, and does not require an external power supply and a secondary instrument.

Classification:
Self-Regulating valves are mainly divided into self-operated pressure regulating valves(ARI-PREDU), self-operated differential pressure regulating valves (ARI-PRESO), self-operated temperature regulating valves (ARI-TEMPRTOL), and self-operated flow regulating valves.

Function:
The self-operated regulating valve uses the feedback signal (pressure, differential pressure, temperature) at the output of the valve to transmit the valve to the actuator to drive the valve flap to change the opening of the valve to achieve the purpose of regulating pressure, flow and temperature.

Advantage:
The self-regulating valve is a new type of regulating valve. Compared with the manual regulating valve, it has the advantage of being able to adjust automatically; compared to the electric regulating valve, it has the advantage that no external power is required. Application practice proves that in the closed water circulation system (such as hot water heating system, air conditioning chilled water system), the correct use of this valve can easily realize the flow distribution of the system; the dynamic balance of the system can be realized; the system can be greatly simplified Commissioning work; can stabilize the working state of the pump.
