Valve type and application

The CASH ACME 24644 is a thermostatic mixing valve designed for plumbing systems that require blended water within a controlled range. It suits residential and light commercial installations where consistent outlet temperature is needed at fixtures supplied by 3/4 in NPT connections.

Installation checks

Verify that your supply lines use 3/4 in NPT threads and that system pressure does not exceed 150 psi. The valve body measures 2 in height and 9 3/8 in width, so confirm the available space in the piping run. Ensure the required temperature range of 90 to 130 F matches the application.

Thermal and pressure performance

The valve maintains outlet temperature across the 90 to 130 F range while withstanding up to 150 psi operating pressure. DZR brass construction resists dezincification in aggressive water conditions. Compliance with ASSE 1017, ASSE 1070 and CSA B 125.3 confirms it meets recognised safety and performance standards for thermostatic mixing valves.

Questions about this item

Does the CASH ACME 24644 valve include any fittings or piping, or must I supply all 3/4 in NPT connections myself?

The valve body has 3/4 in NPT inlet and outlet ports. No fittings, tubing or adapters are included, so you must provide all connections separately.

The specs list ASSE 1017, ASSE 1070 and CSA B 125.3. Which one should I follow when choosing this valve for my installation?

All three apply. ASSE 1017 covers point-of-distribution temperature control, ASSE 1070 covers point-of-use protection, and CSA B 125.3 is the Canadian material and performance standard.

Once installed, what does the 90 to 130 F range actually deliver at the tap?

The valve blends hot and cold water to maintain any set-point between 90 and 130 F, provided inlet pressures are balanced and supply temperatures are adequate.
