A matrix of the combinations with corresponding flow rates can be made available or please call Customer Service (704-922-9565, toll free: 800-354-4297) for more support to determine the flow rate. What is the accuracy range of Hays Automatic Balancing Valve? The design flow accuracy of Hays Automatic Balancing Valves is ± 10% of the nominal flow rate. This is equivalent to +/- 5% heat transfer effectiveness. More information on Mesurflo Automatic Balancing Valve tolerance can be found in our Gold Standard Brochure . Does Hays Automatic Balancing valves require straight lengths of straight pipe upstream or downstream for proper operation? No, Hays Automatic Balancing Valves do not require straight length of pipe before or after for proper operation. ATC VALVES ACTUATED TEMPERATURE CONTROL What ATC suppliers do you use? Hays currently uses Schneider Electric and Belimo Control Valve manufacturers but can source other brands based on customer requests. What type of ATCs do Hays currently offer in their product line? Hays offers the following basic types of ATCs on their packages: • On/Off Control – also referred as 2-position or Zone Valve • Floating Control – also referred as 3-point control • Proportional Control – also referred as Modulating control Where can I find the wiring diagram for ATC? Please contact Hays Customer Service quotes@haysfluidcontrols.com or by calling 800-354-4297 with specific ATC model quoted or selected for the project and we will be happy to provide additional details including wiring diagram for every specific model sourced from Hays. Does Hays offer Normally Open or Normally Closed selection for ATCs on Hose Kits? Yes Hays offers both options for ATCs on Hose Kits, more information on our ATC (Zone Valves) can be found in the Components section of our website. Which valves incorporate multiple orifice plates? The large, high flow valves have multiple orifice plates, specifically, the 2530, 2535, 2540, 2545, 2546, 2547, 2548, and 2570 valves. How does the Automatic Balancing Valve perform in conjunction with modulating ATC valves? Is it still effective and(or) required? The Automatic Balancing Valves helps to limit the flow to the maximum design flow at all conditions with respect to branch-to-branch variation when Modulating ATC valve is fully open. The Modulating ATC can thereby be used to modulate the flow below design flow to affect the temperature difference across the coil. It is very critical to size the Modulating control valves based on the system to provide better authority and system stability. More information on how Mesurflo® Automatic Balancing Valves perform with modulating zone valves can be found on our website here: Modulating Flow Control with Mesurflo
