Data Center Liquid Cooling Thread Brass Static Balance Valve

Data Center Liquid Cooling Thread Brass Static Balance Valve

System Application

J&O series balancing valve can be widely used in heating and cooling systems, domestic water systems, cooling tower circulation systems, and hydraulic circulation systems such as dehumidification. It balances the resistance by calculating the resistance between the primary main pipeline and each graded pipeline,then adjusts the Kvs value using a differential pressure gauge to distribute the flow rate. It is used together with a differential pressure control valve to stabilize the pressure difference between the supply and return water, automatically eliminate interference from system pressure changes, and maintain the pressure difference between the static balancing valve and the differential pressure control valve within a stable value.To ensure that the downstream valve of the return water does not experience over flow or water shortage to achieve optimal working conditions.

Cooling installation (flow) with manual presetting valves. In order to balance the cooling installation manual presetting valves should be mounted on each terminal unit, branch and riser.

Functions

The static flow balancing valve is suitable for achieving hydraulic balance between various loops in the circulating system, and accurately adjust the flow rate of each branch or terminal.

J&O series balancing valve also has an on/off function, with a reliable opening locking memory device to restore the system to its original setting state after maintenance and repair, ensuring that the circulating system can operate correctly according to the initial design conditions, providing the most reasonable cold and hot values, and minimizing energy consumption.

Working Principle

The flow balancing valve is used to regulate the media flow passing through its valve body. By rotating the control valve handle, the balancing valve stem moves up and down to adjust the flow path and change the flow curve characteristics. The pressure testing points equipped on the balancing valve body are used to measure the pressure difference, then the flow can be detected and adjusted based on the pressure difference.
