  Self-actuated pressure regulating valve is widely use in industry, it is a kind of control device which can automatically regulate their own pressure. Control and execution of the instrument control system. Its types can be divided into self pressure (micropressure) control valve, self pressure (differential pressure) flow control valve, and electromechanical temperature regulating valves. It is suitable for use in city heating, power supply and supply to control the situation.

  Urban heating and heating systems adopt the product with thermal efficiency increased by 30 % ~ 40 %. Remarkable energy-saving effect.

  The principle of the self-actuated regulator is briefly described below.

  The working principle of the pressure regulation after the pressure relief valve: There are two kinds of valve and valve control. The valve pressure P1 is adjusted to the valve back pressure P2. P2 is input into the upper membrane chamber through the pipeline on the role of the top plate, the generated force balances with the reaction force of the spring, determines the relative position of the spool, the valve seat and the back pressure control valve. The force acting also on the top plate increases when P2 increases. At this time, the force on the top plate is greater than the reaction force of the spring to close the valve seat to the valve. Then the circulation area between the spool and the valve seat is reduced, the flow resistance increases, and P2 decreases, until the force on the top plate balances with the spring reaction force, so that P2 is reduced to the set. Similarly, when P2 decreases. The direction of action is the opposite of above, which is principle of the pressure regulation behind the valve is also very broad. The application of pressure regulating valve is also widely used in the medium with higher viscosity.
