The AY McDonald 7214 Series Unmeasured-Flow Reducer (UFR) Inline Accessible Dual Check Valve is 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 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.
