Pressure Independent Control ValveModulating control valve, dynamic balancing valve and differential pressure control valve in one body. Field adjustable, self-balancing, dynamic flow control valves that are pressure independent, two-way and modulating to accept analog signal inputs. Each valve has an adjustable maximum flow rate setting to enable flow limitation and balancing to the coil or zone that the valve is controlling.

Advantages of Bray ATT Valves -

1. Installation costs - up to 60% fewer valves are required. Due to the automatic balancing of each heat exchanger, no other differential pressure control valves or balancing valves are required. This simplifies installation, reduces installed costs, and improves accuracy and reliability.

2. Operating costs - Minimizes pumping, heating and cooling costs by eliminating overflow through the coil and by reducing pressure drop.

3. The location of the Bray ATT automatic balancing valve does not require lengths of pipe before or after the valve.

Features and Benefits

• Field Adjustable, up to 41 different flow rates in one and the same cartridge

Flow rate can be changed on demand without removing the cartridge from the valve body

• 100% Authority Pressure Independent

The valve will always use full stroke of the control element offering the 100% authority for any of its 41 flow settings

• Up to 60 GPM of flow capacity for high volume applications

• NPT or BSP female by female threaded connection

Secure, leak free connection to most common applications

• Optional Pressure/Temperature Measurement Ports

Allows for verifying operating differential pressure across the valve

Auto Stroke OptionWith the auto stroke option activated, the actuator will make one full cycle every 24 hours, if the actuator constantly has been in fully open or fully closed position during the previous 24 hours.

This operation will clear up any possible impurities accumulated in the valve, and re-calculate the end positions.
