Our female swivels are British Straight Pipe Thread (BSPT), not directly compatible with American straight thread. That said, BSPT Adapters are available to transition to American straight threads, NPT, NPSH, JIC, and other thread types. If sizes over 2” are available on Hose Kits, why aren't they published? Some of the configurations are not available under standard lead time or may not be stocked component and so it’s always advantageous to contact our Customer Service at 800-354-4297 or email us at quotes@haysfluidcontrols.com to assist you with the best engineered configuration for your needs. What is the default Mesh size for Strainer on Hays Packages? Can the mesh size be altered? The strainer on Hays packages comes with 20 Mesh size as default selection. Hays do offer other mesh sizes upon customer request. AUTOMATIC BALANCING AUTOMATIC BALANCING SOLUTIONS How do I "set" a valve that is automatic? Can I adjust the flow within the same valve? Hays Automatic Balancing Valves are designed to maintain one specific design flow rate value constant within published operating pressure differential range. The design flow rate is not field adjustable, but you can alter internals in most of the Hays Automatic Balancing Valves to achieve a different flow rate if the correct design flow rate was not picked during selection. Contact Hays Customer Service ( quotes@haysfluidcontrols.com or by calling 800-354-4297) for more details. How can I tell what the flow rate is on Hays Automatic Balancing valve installed in the system? Flow rate data is on the information label on the valve. In the event the label is not legible, use common flow measurement devices to determine the flow. Does Hays offer Automatic Balancing Valves in Bronze or Stainless Steel material? Hays offers Automatic Balancing Valves in Bronze C83600 and 316 Stainless Steel body material. You can find more information on our Marine Applications pages. How do the Internals of Hays Automatic Balancing Valves work?

Does Hays offer combination of Isolation Ball Valve and Automatic Balancing Valve, both integrated into one valve? Yes, Hays offers variety of integrated combo designs in different sizes and connections such as 2514, 2515, 2516, 2519, 2524 and 2528 as Automatic Y-Ball Balancing Valves. If you had an Automatic Balancing valve in your possession with label not legible, how would you determine its flow rate? The flow rate is determined by the combination of the orifice plate and the diaphragm combination. The orifice plate has a letter on it while the diaphragm has a colored indicator on one side. 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
