GA-414-Flow-Control-Valve, also known as 400X flow control valve, is a multifunctional valve that uses high-precision pilot mode to control flow.

1. A change to the principle of reducing the area of ​​the watershed by using an orifice plate or a purely mechanical throttle in the conventional throttle valve, and using the relevant pilot valve to minimize the loss of energy during the throttling process
2. High control sensitivity, safety and reliability, easy debugging and long service life.
The flow control valve can automatically realize the flow balance of the system without an external power supply. The flow is limited by keeping the pressure difference between the front and rear of the orifice (fixed aperture) constant, so it can also be called a constant flow valve.
The object of constant flow valve is flow, which can lock the amount of water flowing through the valve, not the balance of resistance. He can solve the dynamic imbalance problem of the system: in order to maintain the high-efficiency operation of a single refrigerator, boiler, cooling tower, and heat exchanger, it is necessary to control the flow of these equipment to be fixed at the rated value; from the end of the system, in order to avoid The mutual influence of dynamic adjustment also requires limiting the flow at the end device or branch.
The problem that should be paid attention to in the design, the disadvantage of the flow control valve is that the valve has a minimum working difference requirement. General products require a minimum working pressure difference of 20KPa. If installed on the most unfavorable circuit, it will inevitably require the circulating water pump to increase by 2 meters of water column. The working head should be installed at the near end and uneasy at the far end. Do not install this kind of flow control valve when the distance between the user and the heat source is greater than 80% of the heating radius.
