Automatic & Manual Balancing Valves – Diagram, Flow Chart & Price List Explained
Efficient hydronic balancing is critical in HVAC systems, and balancing valves are the solution. Whether you're managing flow in a chilled water line, hot water system, or industrial plant, using the correct manual or automatic balancing valve ensures optimal flow distribution, energy savings, and system reliability.
As a reputed manufacturer and supplier in Delhi, Udhhyog offers a wide range of manual and automatic balancing valves that suit modern plumbing and HVAC applications.
This article explores the types of balancing valves, their working mechanism, diagrams, flow charts, and current market prices to help you make the right choice.
What Are Balancing Valves?
A balancing valve ensures that each branch in a fluid distribution system gets its desired flow rate. These valves help maintain hydraulic balance, which is especially crucial in HVAC and hot/cold water supply systems.
There are two main categories:
Manual Balancing Valve: Manually adjusted to regulate flow.
Automatic Balancing Valve: Self-regulating valve that maintains flow irrespective of pressure changes.
Manual Balancing Valves – Overview
✅ Working Principle
Manual balancing valves operate by adjusting a handwheel or calibrated dial. The installer sets the valve to a specific position based on flow requirements.
✅ Applications
Chiller lines
Cooling towers
Terminal units in HVAC
Radiator circuits
✅ Advantages
Cost-effective
Simple to operate
Suitable for steady-state systems
Automatic Balancing Valves – Overview
✅ Working Principle
Automatic balancing valves use a spring-loaded diaphragm or cartridge to keep differential pressure constant. This maintains a fixed flow rate regardless of system pressure changes.
✅ Applications
High-rise buildings
Variable load HVAC systems
Systems with pressure fluctuations
✅ Advantages
No need for recalibration
Maintains consistent performance
Reduces energy consumption
