What is a balancing valve used for?
The role of balancing valves are to control the flow rates in each of the buildings branches to deliver the desired flows in low temperature, chilled, or hot water applications. At each heat exchanger the balancing valve is set to provide the desired flow rate to maintain comfort and energy.
What is the purpose of balancing valves in a hot water system?
This balance valve allows the plumbing contractor to have the system balanced by throttling the valve. The ports provided allows reading out the pressure drop and referring to programs or tools to determine the flow rate during and after adjusting the valve.
What type of valve is balancing valve?
Types of Balancing Valves Static balancing valves—also called manual balancing valves or pressure-dependent balancing valves—offer a fixed resistance to water flow. The settings for these valves are calculated before installation and then adjusted when the valves are installed in the field.
What is a circuit balancing valve?
Circuit balancing valves (CBVs) combine a double regulating valve with a primary measuring element for determining and adjusting hydronic fluid flow in an HVAC system. CBVs are an effective means of ensuring occupant comfort in buildings incorporating hydronic heating or cooling systems.
How do I balance my water system?

What is the difference between a circuit setter and a balancing valve?
Circuit setters feature a built-in balancing valve system and monitoring and measuring points allowing for automatic calibration of the water system. Manual balancing valves come with a wide range of benefits, including the capability to read low rates of flow very accurately while saving energy.
What is chilled water balancing?
The aim of chilled water balancing is to apply a disciplined procedure of adjustment to water flow rates throughout the chw system to meet the particular requirements of the design. Determine the shut-off pressure differential, check against the manufacturer data to zero flow then slowly re-open the discharge valve.
What is valve and types?
Classification of Valves Based on The Way it Open and Closed
| Valve type | Linear motion | Rotary motion |
|---|---|---|
| Folding-disc check valve | X | |
| In-line check valve | X | |
| Stop check valve | X | X |
| Ball valve | X |
What is a balanced cold water supply?
Balanced cold water connection – equal pressures to mixer taps/showers.
How do you balance a geyser?
For a balanced system the cold water supply to baths, basins, showers etc must be taken off the supply between the pressure control valve and the geyser. The pressure control valve reduces the cold water pressure to the same pressure of the hot water coming from the geyser.
What is a calibrated balancing valve?
Calibrated Balancing Valves. This system balance method involves pre-setting the valves to achieve optimum system flow balance (at minimum horsepower) using the manufacturers performance curves.
What are the types of balance valves?
The three most common balancing valve configurations are (1) calibrated manual balancing valve , (2) flow-measuring venturi or orifice plate with manual ball or butterfly valve, and (3) automatic flow-limiting (or automatic flow control) valve.
What is a Magna valve?
A magna cleaning valve or mag valve is fitted prior to the water entering the boiler on the inward water feed (generally above the boiler. It purifies the water removing dirt, grime debris and prevents a build up in the radiators and heat exchanger.
What is BAC valve?
The BAC valve is part of an air feed line that directs air taken before the throttle plates (in the the air funnel) to the intake manifold after the throttle plates. This air “bypasses” the normal path of air to the intake manifold which is via the throttle bores.
What is a flange valve?
A flange valve is a particular type of valve where a raised surface, usually in the shape of a lip or ring on the end of the valve fitting, is mated to a groove on the facing to which it attaches.
