V4944/V8944B,C,L,N
Regulating Diaphragm Gas Valves
APPLICATION
The V4943/V8943B and N (single stage) and V4944/V8944B
and N (two stage) are solenoid-operated diaphragm valves
suitable for natural gas only. The V4943/V8943C and
V4944/V8944C and L are solenoid-operated diaphragm
valves suitable for Liquefied Petroleum (LP) gas only. These
valves are used on boilers, unit heaters, duct furnaces,
makeup air and rooftop heaters.
FEATURES
• Models are available for natural or liquid petroleum
(LP) gases.
• Valve models L, N are rapid opening (less than six
seconds) and fast closing, and are available for LP and
natural gases, respectively.
• Line voltage with two-wire thermostat or controller is
used with V4943; V8943 is used with 24V thermostat or
controller.
• V4944 is used with line voltage dual-stage thermostat
or controller; V8944 is used with 24V dual-stage
thermostat or controller.
• Slow opening B,C valve models are available for
natural and LP gases respectively.
• Valve closes on power failure; recommended for final
shutoff service.
• Valve closing time: 2 seconds maximum at 7 inches wc
inlet pressure.
• Valves rated for 0.5 pound per square inch (psi) (3.4
kPa).
• Leadwires and cover for electrical conduit connections
are provided.
