Honeywell V9055A User Manual

PRODUCT DATA
60-2311-11
V9055A,D Modulating Fluid Power
Gas Valve Actuator
APPLICATION
The V9055 Gas Valve Actuator in combination with a V5055,
VE5000
a
or V5097 Gas Valve provides modulating control of
the gas supply to commercial and industrial burners.
a
VE5000 is a European manufactured and approved valve for
European use only.
FEATURES
• Actuator opens the valve to the low-fire position when
energized. Actuator then modulates to meet firing rate
controller (Series 90) demand.
• Actuator is equipped with an integral shaft that may be
used to drive a combustion air damper in unison with the
gas valve.
• The V5055 or V5097 Gas Valve includes a yellow SHUT
indicator. The actuator includes a red OPEN indicator. The
indicators provide constant visual indication of valve
position.
• Actuator can be used with all VE5000
a
, V5055 or V5097
Valve models; however, the V5055B or V5097B with
characterized guide is recommended for optimum control
and low-fire repeatability.
• Ambient temperature range for 60 Hz models is -40°F to
125°F (-40°C to 53°C). Ambient temperature range for 50
Hz and 50/60 Hz models is -10°F to 125°F
(-23°C to 52°C).
• Auxiliary 1/2 hp rated switch is available for field
installation.
• Integral damper shaft provides a maximum of 20 lb
(9 kg) of force.
• Valve and actuator may be mounted in any position.
• Model is available with NEMA 4 (IP54) weatherproof
enclosure.
• V9055D/V5055C,E and V9055D/V5097C,E combinations
available with proof-of-closure switch and two valve seals
(valve seal overtravel interlock) to meet specific code/
standard/insurer requirements.
• Field addable adapter available for 4-20 dc mA control of
actuator.
• When replacing a V9034 Actuator with a V9055, the V5034
Valve body must also be replaced with a V5055 or V5097
Gas Valve.
NOTICE: Per Industry Standards, the actuator is required a
conduit seal or a cable type that is sealed be installed in a
device that can result in a flammable liquid flow through a
conduit or cable to an electrical ignition source in the event
of a seal leakage or diaphragm failure.
