Components for today’s modern hydronic systems
High flow adjustable thermostatic mixing valve,
5231 series, for commercial point of distribution
domestic water and radiant hydronic systems,
DZR certified low lead brass, 1”— 2”, sweat
and NPT union.
Anti-scale materials prevent scaling on internal
sliding parts, that reduces jamming caused by lime
deposits, assuring reliable, constant temperature
setpoint and long, trouble-free operating life.
Adjustable thermostatic and pressure balanced
mixing valve, MixCal
TM
521 series, for residential
point of distribution domestic water and radiant
hydronic systems, certified low lead brass, ½”—1”,
sweat and NPT union, ¾ press union.
Optional outlet temperture gauge speeds up
the temperature setting process and provides
dedicated proof-of-temperature verification to aid
in the commisioning process (521, 5231).
Adjustable thermostatic and pressure balanced
mixing valve, 5213 series, for residential point of
use (scald protection) domestic water systems with
locking setpoint, certified low lead brass, ½”—1”,
sweat and NPT union.
Check valves in inlet hot and cold ports (standard
for 5213 series, optional for 521 and 5231 series).
