ATT Series Adjustable PIC Valves 2 Way 1/2-1-1/2 ATT - AutoTouch Terminal

1 ½ -1½ - Pressure Independent ontrol Valve - Modulating 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. dvantages of ray TT 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 ray TT automatic balancing valve does not require lengths of pipe before or after the valve. ody Style & D TT Series djustable PI Valves 2 Way 1/2-1-1/2 TT - utotouch Terminal ody Style - System Types: - Media: Fan oil, VV Reheat oils, ot Water, hilled Water, hilled eams and ir andling Units 50/50 Glycol Solutions. 11/13/13 Features and enefits Field djustable, 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% uthority Pressure Independent The valve will always use full stroke of the control element offering the 100% authority for any of its 41 flow settings uilt-in Isolation all Valve (ody Style and D) llows for coil isolation Female-by-Female Threaded (ody Style ) Double Union End onnection, Threaded or Sweat (ody Style and D) For ease of installation and wide selection of end fittings Optional Pressure/Temperature Measurement Ports llows for verifying operating differential pressure across the valve TT-1

6 TT - ow it Works Dynamic Flow Rate Limiter djustment The utotouch Terminal (TT) is set to 1 of 41 settings of maximum flows with the adjustment key. Turn the adjustment key to numerals 1 through 5 with the decimals appearing in red. Flow Rate can be changed on demand without removing the cartridge from the valve body. Flow Flow artridge djustment with Key Rotates with Key to adjust Flow Principle of Operation The function of the TT valve is best described as three functions in one. The first valve regulates the pressure differential across the second valve by means of a rolling diaphragm element counteracted by a spring. The second valve is a calibrated variable orifice device adjusted by the actuator (similar to a standard modulating control valve). Dynamic alancing of Flow The diaphragm reacts to the system and regulates the pressure differential across the actuated control valve orifice to maintain its flow rate. Go to the following web address to see a video demonstration: www. braycommercialdivision. com/att.mov Indicates Flow Direction Indicates Pressure hanges Full Stroke Modulation 100% authority guaranteed. hanging the setting will not affect the stem height as the setting merely turns the inner bottom part of the cartridge sideways. t any setting the stem height will remain the same providing full stroke.
