Balancing of valves is key to achieving hydraulic balance in HVAC and plumbing systems, which in turn ensures even flow and best performance. As top-of-the-line Balance Valve Manufacturers in India, Speciality Valve brings to you a large selection of manual and automatic balancing valves. We also have what you need for chilled water, heating circuits, and large-scale industrial systems.
What Is a Balancing Valve?
A balancing valve is a special type of control valve that is put in to regulate flow rates and pressure in piping networks to achieve balance. It also sees to it that proper distribution and protection are given to downstream equipment in HVAC and hydronic systems.
In the design of hydronic systems, we use these valves to even out water distribution, which in turn at large reduces energy use and operation costs.
How Balancing Valve Works
Balancing valves do so by producing a controlled pressure drop across a variable orifice or spool. As flow and pressure variations present themselves, the valve responds to unbalance, thus see to it that all branches get the design flow. Static or manual balancing valves have preset adjustments, pressure-independent or automatic versions instead adapt to changes in real time.
Static (manual) balancing valves come in at a set resistance, which is determined at the time of installation. Automatic balancing valves can adjust internal components (like spring cartridges), which in turn maintain constant flow regardless of pressure changes.
Balancing Valve Components
- Valve, which is controlled by a handwheel for manual adjustment.
- Orifice or Spool outflow for balance.
- Test ports for connecting pressure gauges, which may be used for adjustment.The
- Memory Lock Set Point System sets the flow at a precise point.
- Automatic Cartridge (for dynamic valves) - Regulates flow during pressure changes.
- At Connectors, threaded or flanged as per system design.
Can a Balancing Valve Be Installed Vertically?
Yes, we see that balancing valves are designed for many orientations. Manual balancing valves, which have handwheel access, may be installed vertically if that does not impair access to test ports and adjustment mechanisms. Also, it is best to refer to the manufacturer’s guidelines for proper operation and accessibility issues, which goes for automatic types also.
What Is a Pressure Balancing Valve?
A pressure-compensated valve, which is designed to maintain constant output as supply pressure varies which is what you see in the case of shower valves, which we use in plumbing fixtures that prevent scalding if the cold water pressure drops.
In the field of HVAC and chilled water systems, pressure balancing valves control differential pressure, which in turn maintains proper flow; they are a stable element in dynamic systems.
How to Adjust a Balancing Valve
Manual balance valve adjustment usually includes:
- Connecting the differential pressure meter to the test ports.
- Calculating target flow using specifications.
- Rotating the dial until the required flow is achieved.
- Tightening the handwheel to set it.
Automatic tuning valves, which do not require manual readjustment, internally, components self-adjust to maintain flow within design limits.
Balancing Valve for Chilled Water
Within water-cooled systems, what we have are balance valves, which see to it that each terminal (which may be fan coil units or chilled beams) gets the right flow for proper temperature control. This in turn produces consistent cooling, energy savings, and uniform comfort across zones.
Balancing Valve vs Butterfly Valve
Industry Use Case - Commercial HVAC Systems
In large commercial HVAC systems found in hotels or malls, which have multiple floors and terminals that are competing for flow without balancing near end units, may overcool while remote units underperform. Manual or automatic balancing valves, which will equalize the distribution of chilled water, are used to address this issue. This, in turn, improves the comfort of the building’s occupants and also results in better energy efficiency from the optimized pump head and coil performance.
Other Applications
- Tuning flow in boiler and chiller circuits for consistent temperature.
- Equal distribution of cooling fluids in server farm loops for reliable thermal performance.
- District energy distribution is metered and balanced across many buildings and zones.
- Flow control in industrial processes requires great accuracy.
- Improving return water systems for better pump performance and energy use.
