V47 Series Temperature Actuated
Modulating Water Valves


The V47 modulating valves
regulate the flow of water to
maintain a desired temperature.
V47A valves OPEN on a
temperature increase at the bulb
while V47N valves CLOSE on a
temperature increase at the
bulb. Refer to LIT-125687 for
pressure actuated water valves.
The V47 temperature valves are
widely used on heat exchangers
to maintain optimum operating
temperatures of internal
combustion engines, air
compressors, hydraulic oil, etc.
Important benefits from the use
of water valves include
maximum operating efficiency of
the equipment and a substantial
savings effected by the
conservation of water flow. They
are used on condenser
applications where expensive
fluids are economically
recovered or where the use of
cooling water is restricted and
on such varied applications as
the temperature control of
swimming pools and the control
of paint temperatures on
industrial printing machines.
Temperature actuated three-way
diverting valves are available for
special applications.

All Series V47 water
regulating valves are designed
for use only as operating
devices. Where system
closure, improper flow or loss
of pressure due to valve
failure can result in personal
injury and/or loss of property,
a separate pressure relief or
safety shutoff valve, as
applicable, must be added by
the user.


· No close fitting sliding parts
in water passages.

· Range spring does not come
in contact with the cooling

· Easy manual flushing, if

· Valve design minimizes
chatter and water hammer.

· Free movement of all parts
provides smooth
temperature modulation.

· Adjustment not affected by
water pressure variations.

· Withstands high hydraulic
shock without damage.

General Description

A pressure-balanced design,
employing synthetic rubber
sealing diaphragms correctly
proportioned to the valve port
area, balances valves against
both gradual and sudden water
pressure changes, seals water
away from range spring and
guides and provides protection
against high water surge
pressures. Range spring and
sliding parts are not submerged
in water where they would be
subject to sedimentation and
corrosion. Only five metal parts,
made of corrosion. Only five
metal parts, made of corrosion
resistant material, come in
contact with the water -- valve
disc holder, disc stud, valve
seat, valve stem, and body.
