Mixing Valves
UMV500-LF/U Series UnderSink Thermostatic Mixing Valve
The UMV500-LF/U Series UnderSink Thermostatic Mixing Valve is
intended for use in under counter and under sink applications. The
UMV500-LF/U Universal Model is designed to be used as a three
port design (touchless sink) or a four port design (two handle sink)
with the addition of the 4 port adaptor (supplied with UMV500-LF/U).
The UMV500-LF/U is used to prevent accidental scalding. The outlet
water temperature must be properly adjusted by the installer using
a thermometer to measure the outlet temperature at the faucet. A
maximum outlet temperature of 110° F (43° C) is recommended.
• Universal design allows flexibility in adapting to three port or four
port applications.
• Shipped with four port adapter.
• Shipped with mounting bracket for easy mounting.
• Integral check valves in hot and cold inlets.
• Lockable hand wheel for tamper resistant temperature setting.
• Lead Free (0.25% max. weighted average lead content)
