SPECIFICATION: (EXAMPLE)
• Thermostatic mixing valve
• Brass body
• Thermostatic element senses the outlet water
temperature and reacts to maintain a constant
delivery temperature even under changing
flows or variations in supply temperatures or
pressures
• Regulating piston made from
Engineered polymer
• Outlet flow reduced to a trickle in the event of a
cold water supply failure
• Snap-on cover over a spindle mechanism that
requires a special tool to adjust
temperature. The special tool is provided with
each valve.
• Supplied with integral poppet style check
valves on both inlets to prevent crossflow
• Inlets/outlets: 1/2" copper sweat
• Outlet temperature range:
95 - 120˚F (35 - 49˚C)
• Hot temperature supply range:
120 - 180˚F (49 - 82˚C)
• Minimum acceptable temperature differential
of hot water inlet to tempered water outlet is
5˚F (3˚C)
• Working pressure:
145 psi (1,000 kPa) max.
• Pressure difference between hot and cold
supply should not exceed ± 20%
• Maximum flow rate @ 45 psi pressure loss –
11.0 gpm (42 L/min)
• Minimum flow rate @ 45 psi pressure loss
– 0.34 gpm (1.29 L/min)
