Floor Heating Valve

Application:

Ordering Information:

The ﬂoor-heating valve (FHV) provides an

economical method of incorporating a radiant

ﬂoor heating system into an existing hot

water or radiator system. FHV self-acting

regulators are well suited to handle underﬂoor

heating temperature in single rooms, such as

bathrooms, entry ways or kitchens.

FHV control valves are ﬂexible to use, easily

installed and are available in two versions:

FHV-A control valves are ideally suited to

control individual underﬂoor heated rooms.

The FHV-A is placed on the supply side of a ﬂoor

heating system, and is capable of providing

hydraulic balancing via the FHV-A’s integral

pre-setting feature. In controlling the room air

temperature a standard RA 2000 operator is

ﬁtted to the FHV-A valve.

FHV-R valves are designed for systems using

ﬂoor heating in conjunction with radiators. The

valve is place on the return side of the radiant

ﬂoor system. The valve’s operator, FJVR, senses

the return ﬂuid temperature of the system

and regulates the valve appropriately. When

the FHV-R is used for a radiant heating system,

the maximum ﬂoor heated area should not be

greater than 110 sq. ft.

Note the ﬂow temperature must not be

permitted to exceed the maximum supplied

water temperature as recommended by

the ﬂoor heating supplier. This can be

accomplished via use of Danfoss’ 3-way (MR)

or 2-way (FTC with RA 2000 or RAVV with VMT)

thermostatic valve and a circulator in the ﬂoor

heating loop.

When ordering the FHV assembly order the valve body, appropriate operator, tail pieces and union

nuts.

Valve bodies include wall box, cover and valve

Code No. Description Cv*

003L1001 FHV-A pre-settable valve body 0.05-0.92

003L1000 FHV-R retur temperature limiting valve 1.03

*Cv is the eater ﬂow rate through the fully open valve at a pressure drop of 1 psi. To determine the pressure drop through the valve

at other ﬂow rates use the formula: ∆P = (Q/Cv)

, where Q = water ﬂow in GPM
