Description
The Leonard Valve 162400 is a matched Checkstop Pair with a rough/flush (RF) configuration, designed specifically for use with Leonard’s TMS-80 series thermostatic mixing valve systems. These checkstops serve as the hot and cold water supply stops for the mixing valve assembly, combining shut-off and check valve functions in a single, compact unit to simplify installation and ensure reliable system performance.
Product Overview
Checkstops are a critical component in any thermostatic mixing valve installation. The Leonard Valve 162400 pair provides independent isolation of the hot and cold supply lines, allowing for easy service and maintenance of the TMS-80 mixing valve without shutting down the broader plumbing system. The integral check valves prevent cross-flow between the hot and cold supplies, protecting system integrity and ensuring accurate temperature control.
