Pressure regulating valve is also known as self-balancing valves, flow control valves, flow controllers, dynamic balancing valves, flow balancing valve, is an intuitive and simple flow adjustment and control device, the application of flow regulating valves in the pipeline network can be directly based on the design to set the flow rate, the valve can be used in the role of the water to automatically eliminate the residual head of the pipeline and the pressure fluctuations caused by the flow rate of deviation, regardless of the system pressure how to change the set flow rate to remain unchanged. Unchanged, these functions of the valve so that the pipe network flow adjustment is completed at once, to adjust the network work into a simple flow distribution, an effective solution to the network of hydraulic disorders. Flow control valve is mainly used in: central heating (cold) and other water systems, so that the pipe network flow distribution according to need, to eliminate the water system hydraulic imbalance, to solve the problem of uneven heating and cooling.
Self-operated pressure regulating valve uses medium energy to regulate pressure difference and flow to achieve pressure reduction and stabilisation, with the advantages of sensitivity and good sealing. Applicable to industrial equipment in the gas, liquid and steam media pressure reduction and stabilisation or pressure relief and stabilisation of automatic control, according to the requirements of the site to adjust the actuator and spring, to adapt to different working conditions.
By receiving signals from industrial automation control system (e.g. 4~20mA) to drive the valve to change the size of the cross-sectional area between the spool and the valve seat to control the flow of pipeline media, temperature, pressure and other process parameters.
