Are circuit setters pressure independent?

Pressure dependent calibrated valves, commonly referred to as circuit setters, are used for pre-set proportional system balancing.

Which way does a balancing valve go?

Shifting viewpoints on flow controls can cause disagreements where balancing valves should be located in closed loop systems. Many (including us at Hays Fluid Controls) agree that the balancing valves should be placed on the return side, whereas other companies may choose the supply side.

What is the purpose of a circuit setter?

The circuit setter was developed by Bell & Gossett so as to ensure an optimum flow balance of water. It is a calibrated balance valve that ensures the balanced flow. This has been introduced to HVAC industry to ensure the optimum flow of water and accurate measurement.

Can a circuit setter be installed upside down?

IMPORTANT: Bell & Gossett Circuit Setter Balance Valves are not recommended for use with meter connections pointing down. Dirt will collect in the connections and foul up the readout valves and readout meters. CAUTION: Excessive use of solder in a vertical installation may result in damage to the valve seat and ball.

Are circuit setters and balancing valves the same?

A Bell &Gossett circuit setter valve is a type of balancing type valve which is commonly applicable in an HVAC or plumbing system to control and manage the pressure in the entire system or inside a part of the system.

Are circuit setters directional?

Circuit Setter Balance Valves are bi-directional valves and can be installed in most altitudes, however, they should be installed in a position to facilitate the ease of balancing the system.

Is a balancing valve the same as a circuit setter?

Why do control valves go on the return?

When a control valve is installed on the return side, the water is at a higher pressure through the coil, reducing off-gas, thereby lowering dissolved oxygen content compared to a supply installation.

Can balancing valves be installed vertically?

The circuit balancing valve is installed with flow in the direction of the arrow, and may be in the horizontal or vertical position. The handwheel can be positioned up or down, or on either side.

What type of valve is a circuit setter?

balancing type valve
A Bell &Gossett circuit setter valve is a type of balancing type valve which is commonly applicable in an HVAC or plumbing system to control and manage the pressure in the entire system or inside a part of the system.

Is a circuit setter an automatic balancing valve?

Circuit setters feature a built-in balancing valve system and monitoring and measuring points allowing for automatic calibration of the water system.

How do pressure independent valves work?

The diaphragm reacts to the system and regulates the pressure differential across the actuated control valve orifice to maintain its flow rate. On a PICV (see graphic below), when pre-setting the maximum flow rate, the inlet orifice changes in size, which does not interfere with the length of the stroke.

Why is control valve on return side?

What is a circuit setter?

Circuit setters are used to balance hydronic systems, and they are required at every terminal in the system, even when there is a control valve present. The only exception to this rule is when the control valve is a pressure independent type, which involves a significant cost increase.

Do I need a circuit setter with a control valve?

NCPE, you couldn’t be any more incorrect in your statement. Circuit setters are used to balance hydronic systems, and they are required at every terminal in the system, even when there is a control valve present. The only exception to this rule is when the control valve is a pressure independent type, which involves a significant cost increase.

Is the Bell&Gossett circuit setter plus suitable for residential buildings?

However, the Bell & Gossett Circuit Setter Plus is meant for HVAC industry only. This system doesn’t cater to residential buildings as they are benefitted with a manual balancing valve. The Bell and Gossett has brought the most innovative products for HVAC industry.

What is a Circut setter in a hot water system?

RE: circut setters. Circuit setters generally are installed at the end of a heating hot water loop to allow there to be continuous flow through the piping system. It is a minimum flow device, they are generally not needed if your system involves 3-way valves.
