balance valve

balance valve

A cooling or heating water distribution system is in balance when the flow in the whole system corresponds to the flow rates that were specified for the design of the system. If the correct balancing of the system is not established, this will result in unequal distribution of the flow so that there will be a surplus effect in some of the terminals, whereas the effect will be inadequate in others. Only a correct set of balancing valves can ensure the correct distribution of the flow in the system. That is to say the balance valve uses the flow technology to ensure that the design flow rate is achieved at all times irrespective of any pressure changes within the system.

From the basic principles of regulation viewpoint balancing valve is actually an instruction manual for the regulation valves. Generally speaking, balance valves consist of valve body, body seat ring, disc, disc seat ring, stem nut, stem, bonnet, yoke, hand wheel and other necessary fittings. The valve body can be manufactured from the brass. And the stainless steel is widely applied to manufacture the other components. The hand-wheel is designed for maximum operator comfort and fine-turning control. For the best of thermal distribution, cooling distribution and pump energy saving. 

Moreover, the balance valves are widely used in heating and air adjusting hydraulic power system. It can adjust the hydaulic power balance, and also has the function of draining dirt, measuring flow volumn and stoping the fluid.
