The AY McDonald 7202 Series Unmeasured-Flow Reducer (UFR) Angle Single Check and Non-Check Valves are an innovative design that allows low volumes of water usage, previously unmeasured by any water meter, to be measured simply by batching the usage. Indicators show that 5% to 10% of total water consumption is lost due to low, unmeasured flows. This device has been in service worldwide.

Standard Model Features Include:

Manufactured in compliance with ANSI/AWWA C800 (latest revision)

Brass components conform to ASTM B62 and ASTM B584, UNS C83600 -85-5-5-5 (latest revision)

Rated for 175 PSIG water pressure

Made in the United States of America

Self cleaning cartridge assembly

For use with volumetric (Positive Displacement) & multi-jet meters

Designed to be installed after the meter – UFR is directional

Available in a non-check valve for use where thermal expansion is an issue

Available in No-Lead brass

Available in additional configurations – call factory for pricing and availability

Thermal Expansion Warning – Creating a “closed” condition in a hot water system with the installation of a non-return barrier (such as a check valve or backflow preventer between the system piping and the public supply) can result in extreme pressure rises caused by thermal expansion and/or water hammer. This thermal expansion can damage piping, valves and other components in the system. The installation of a pressure relief device or thermal expansion tank can avoid possible damages.
