Bav Series Dynamic Control Balance Valve

The phenomenon of hydraulic imbalance in fluid distribution network will lead to the following hazards: (1)It may cause damage to the pipe network, bring breakdown, even lead to the accident. Excessive flow will have a greater impact to pipe and equipment, bring vibration and noise, affect the life of the pipe network, and equipment, too low flow will also cause the equipment to stop or protect, then the pipe network will not as usual.

(2)It will impact the working performance of pipe network, if the actual flow and design capacity dose not match. For example, in the heating and air conditioning system, the hydraulic imbalance will impact the effection of heating and air conditioning directly.

(3)Waste more energy. The exceeded design flow of some branch in pipe network or equipment, will cause additional energy wasted. While too low flow of some branch needs to increase the pump power to meet the work demands, resulting in increased energy consumption.

Benefits brought by dynamic flow balance valve

(1)easy to design. No need to check the resistance and flow, greatly improve the design speed.

(2)Save the invest expenses. The entire water system is simple, reliable, no need to install the pipe with the same route, saving installation and material costs.

(3)Save the operation expenses. The whole system works in the balance situation to confirm the pump and other device under low energy -cost.

(4)Quicker and more convenient usage. No need manly checking, saving a lot of labor, shorten the building time. It could not impact the design and balance in other part of water system if some pipe needs to change the flow.

(5)Improve the safety. Confirmed water flow, prohit the human error accident, improving the safety of metallurgy, electricity, petrifaction and so on.

(6)Improve the durability. Confirm the balance of flow, aviod the damage of pipe and equipment because of the excessive flow.

(7)Save the space of buildings because of the simple arrangement of pipe net.

Work principle

(1)The valve is fully compressed over the range of control pressure difference, the flow area keeps constant at the minimum ones, the flow varies with the pressure difference.

(2)The valve is moved by the pressure difference, the flow area changes to keep the flow at the set value.

(3)The valve guts fully extended under the range of control pressure difference, exposing the maximum flow area, flow changes with the pressure difference.

Note: The small -caliber bile dynamic flow balance valve is consisted by single bile valve, large diameter dynamic flow balance valve is consisted by one or more valves bile, different bile combination caused different flow settings.
