What is a TA valve?

TA Modulator is the new highly precise pressure independent control valve for perfect temperature comfort in all heating and cooling applications. The new valve insert with uniquely shaped EQM characteristic (patent pending) provides outstanding ability to precisely control even very small flows.

What does a circuit setter do?

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 you install balancing valves vertically?

The arrow must align with the direction of fluid flow. NIBCO balancing valves may be installed in either horizontal or vertical lines.

How do you size a balancing valve?

Sizing balancing valves based on the minimum or maximum flow rates is not recommended. Valves should be sized using the nominal flow rate only. The Minimum Flow is calculated from the minimum open setting of the valve and a minimum pressure drop 1 Ft.

What does the modulating control valve allow you to control?

A modulating control valve is an automated valve that is used to control the amount of flow in a system or process. They go beyond simple shutoff or isolation (on/off) and actually allow precise control of the flow rate.

What is a motorized valve?

A motorized valve is a valve type that use an electric motor to open or close its mechanism. This type of valve is ideally suited to very large valve types or remote fluid control applications such as aircraft deicing, agricultural irrigation,and automated fire suppression.

When would you use a circuit setter?

When it comes to plumbing, a circuit setter valve is used to optimize the pressure between hot and cold water within the potable water system. The earlier trends were to use a check valve and a ball valve.

Can balancing valves be installed upside down?

– Valves can be installed with the stem pointing in any direction, but the prefered stem position is vertical. – Valves should be installed upside down only, if the medium being handled is clean.

Can a circuit setter be installed vertically?

CAUTION: Excessive use of solder in a vertical installation may result in damage to the valve seat and ball. Care should be taken to prevent overtightening of the readout valves which may damage the Circuit Setter.

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.

Where should balancing valves be placed?

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 are the different types of circuit setters?

For larger sized systems, Circuit Setters are available in ball style (2 1/2” – 4”) and globe style (4” – 12”). Our globe style valves include a multi-turn stem, calibrated nameplate, memory button for easy re-setting of the valve position after shut-off/isolation, and integrated pressure/temperature ports.

What is the Bell and Gossett circuit setter plus?

The Bell & Gossett Circuit Setter Plus is a calibrated balance valve designed for pre-set proportional system balance. Since its introduction to the HVAC industry in 1968, the Bell & Gossett Circuit Setter has set the standard for proportionally balancing hydronic HVAC systems.

Can a balance valve be installed in a circuit setter?

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

What kind of body does a TA 789 balancing valve have?

TA Series 788 and 789 balancing valves have ductile iron bodies and Ametal or ductile iron trim, depending on size. Test ports feature self-sealing construction for 789 balancing valves. Product Description: balance all flow rates.
