Flow control valve, also known as 400X flow control valve, is a versatile valve that uses high-precision pilot flow control. Suitable for the distribution pipe to control the flow and pressure of the pipeline, to maintain a predetermined flow rate, the flow will be limited to a predetermined value, and appropriate to reduce the upstream high pressure, even if the main valve upstream pressure changes, it will not affect Flow downstream of the main valve. 1, A change to conventional throttle orifice plate or purely mechanical principle of reducing the basin area, the use of related pilot valve to minimize the energy loss in the throttling process 2, the control of high sensitivity, safety and reliability, commissioning Simple, long service life. The flow control valve automatically balances the flow of the system without external power. Flow through the orifice plate (fixed aperture) before and after the pressure difference to achieve a certain flow rate, therefore, can also be called the flow valve. Fixed flow valve is the role of object flow, to lock the flow of water through the valve, rather than against the balance of resistance. He can solve the system's dynamic imbalance: In order to maintain the efficient operation of a single chiller, boiler, cooling tower, heat exchanger these devices need to control the flow of these devices is fixed at the rated value; From the end of the system, in order to avoid Dynamic adjustment of the interaction, but also need to end the flow of devices or branches. In the design should pay attention to the problem of flow control valve is that the valve has the shortcomings of poor work requirements, the general requirements of the product minimum working pressure 20KPa, if installed in the most adverse circuit, will inevitably require more circulating water pump 2 meters of water column Working lift, it should be taken near-end installation, distal uneasy approach. Do not install this flow control valve when the user is at a distance greater than 80% of the heating radius from the heat source.
