FHV-A / FHV-R
Floor Heating Valve
Tail pieces and union nuts require two of each
013U0496 1/2” Union Nut
013U8608 1/2” Solder Female Tailpiece
013U0496 1/2” Male Threaded Tailpiece
The installation of either valves should be on a closed loop system
Maximum Flow Temperature 194°F (90°C)
Maximum Operating Pressure 87 psi (6 bar)
Maximum Differential Pressure (water) 8.7 psi (0.6 bar)
In laying a radiant floor heating system with the FHV valve, it is recommended to utilize the double
parallel spiral pattern otherwise known as the counter flow tube layout.
The water supply temperature for the system
should be properly monitored to ensure the
surface temperature is appropriate for the
finished floor material.
The maximum square footage allowed for the
FHV-R application is 110 sq. ft. Since the FHV-R
valve monitors the fluid temperature and not
the air, it will not completely close. The adjusted
set temperature for the operator should be
appropriate for the finished floor material.
