Hot Water Master Mixing Valve

The Powers LFMM433-1 is a brass mixing valve designed for hot water systems requiring precise temperature blending. It serves commercial and residential installations where a master valve controls mixed water delivery to multiple outlets. The unit handles a flow rate of 110 gpm through 1 1/4 in FNPT inlet and outlet connections. It meets ASSE 1017 and CSA B125 standards for performance and safety.

Sustained Load Behaviour

The valve maintains stable outlet temperatures across a range of 90 to 160 Degrees F during continuous operation. It accepts hot inlet temperatures from 120 to 180 Degrees F and cold inlet temperatures from 40 to 80 Degrees F without losing control accuracy. Maximum working pressure is rated at 125 psi, allowing reliable service in high-demand recirculation loops. Internal components resist scaling and wear under prolonged thermal cycling.

Build Quality and Connections

The body is constructed from cast bronze for corrosion resistance and structural rigidity in potable water applications. FNPT threaded ports on both inlet and outlet simplify integration into existing copper or steel piping without specialised tools. Overall dimensions of 9 1/4 in height by 15 1/2 in width define the space required for installation and servicing access. The brass construction supports long-term durability in hard water conditions.

Questions about this item

Does the LFMM433-1 mixing valve generate noise, heat or draw power when it runs continuously?

The LFMM433-1 is a purely mechanical brass valve with no electrical components, so it produces no noise, heat or power draw during all-day operation.

What piping or fittings must I already have to install the LFMM433-1 mixing valve?

You need 1 1/4 in FNPT threaded hot and cold supply lines and a matching 1 1/4 in FNPT outlet connection to mate with the valve's inlets and outlet.

Will the LFMM433-1 mixing valve work with my existing 120 °F water heater and 40 °F cold supply?

Yes — the valve accepts hot inlet temperatures from 120 °F to 180 °F and cold inlet temperatures from 40 °F to 80 °F, then blends to an adjustable 90 °F–160 °F outlet range.
