Digital locked balancing valve structures characteristics
The figure below shows the curves of the flow performance of several valves, of which one of an equal percentage performance is made in my company. It can get known one equal variable rate with the opening makes the variable rate of flow equal, which features by the bigger the opening, the bigger the flow while the smaller the opening the smaller the flow. Most of the application in engineering is do neat a big flow, so this equal percentage valve is just suitable for this requirement.
Digital locked balancing valve purpose
This is a balancing valve, suitable for various liquid pipeline
systems, and is an ideal brand-new energy-saving valve, set with a
scaled digital display and visually adjustable to any position and
lockable.
Main used for the warming pipeline system of industrial and civil
buildings. It provides the means to settle such a problem existing
in some pipe-net systems as the hydraulic imbalance and can
accurately adjust both step-down and flow so as to improve the
flowing status of the liquid inside of the pipe-net system to reach
the target of the liquid balancing and energy saving. Use of this
valve in the reform of the dual-pipe network engineering can still
save energy and get a better effect.
