Powers' HydroGuard ® XP Series SH1434 & LFSH1434 Triple, Quad and Six Valve
Hi/Lo's are fully assembled, factory tested systems, designed to provide safe
water throughout commercial and institutional facilities. Each consists of MM434
or LFMM434 and SH1434 or LFSH1434 Master Tempering Valves which utilize par-
affin-based actuation technology to sense and adjust outlet temperature. Each
system includes a PRV, ball valves, pressure/temperature gauges and Powers'
triple-duty check stops and are supported by heavy-duty welded struts. Optional
equipment includes cabinets and/or Powers' AquaSentry ® 2 high-temperature
alarm system. (Not available with LFSH1434 Series).

*With Equal Pressure
**Minimum flow when Hi/Lo valve is installed at or near hot water source recirculating tempered
water with a properly sized continuously operating recirculating pump.
***Note: Low limit cannot be less than the cold water temperature. For best operation, hot
water should be at least 5°F (3°C) above desired set point.

Operation
n
The Triple, Quad and Six Valves Hi/Lo feature one low capacity valve that works in
parallel with multiple high capacity valves. During low demand, the low capacity
valve handles the load requirements. As the load demand increases, the pres-
sure reducing valve, which is set at a certain pressure differential, will open and
allow flow through the high capacity valves to assist the low capacity valve in
meeting the increased load requirements.

WARNING: TO ENSURE THE
ACCURATE AND RELIABLE
OPERATION OF THIS PRODUCT, IT IS
ESSENTIAL TO:
• Properly size each valve based on the indi-
vidual application.
• Properly design the recirculation system to
minimize pressure and temperature variations.
• Conduct an annual maintenance program to
ensure proper operation of all critical com-
ponents.
THIS VALVE MUST BE USED IN
CONJUNCTION WITH TEMPERATURE
ACTUATED POINT-OF-USE DEVICES THAT
COMPLY WITH ASSE 1016, 1069, OR 1070.
FAILURE TO COMPLY WITH PROPER
INSTALLATION INSTRUCTIONS COULD
CONTRIBUTE TO VALVE FAILURE, RESULTING
IN IN JURY OR DEATH.
