The VSHB static balancing valves are primarily installed in the risers, branch pipes, and terminal units of HVAC systems. Their core function is to accurately preset the maximum flow rate of the pipeline by manually rotating a numeric handwheel in conjunction with a balancing instrument. This process eliminates hydraulic imbalances such as overflow or underflow within the water system, ensuring static hydraulic balance across all branches and enabling the entire HVAC system to operate stably and energy-efficiently.

Feature

1.Pressure-Balanced Plug Design

Feature: The plug adopts a pressure-balanced structure, which significantly offsets the axial thrust exerted by the medium pressure on the plug.

Advantage: Manual adjustment or operation remains effortless and smooth regardless of system pressure, ensuring higher commissioning accuracy.

2.High Flow Coefficient

Feature: Optimized internal flow path design provides a higher Kv value.

Advantage: Minimizes resistance (pressure drop) at the same flow rate, reducing system energy consumption and achieving building energy savings.

3.Precise Numeric Handwheel

Feature: Equipped with a clear digital scale display (typically accurate to 0.1 turns).

Advantage: Operators can intuitively read the current valve opening, facilitating repeatable settings and precise commissioning.

4.Full Shut-off Function

Feature: Beyond its balancing function, the valve provides excellent sealing performance.

Advantage: It can serve as an isolation valve during system maintenance or equipment repair, eliminating the need for additional shut-off valves.

5.Self-sealing Test Ports

Feature: The valve body is equipped with two self-sealing measurement points.

Advantage: Allows rapid connection of differential pressure gauges or flow meters for flow measurement, venting, or draining without leakage upon removal.
