Honeywell V4295A, V8295A, V4295S, V8295S Installation Instructions Manual
V4295A,S; V8295A,S
Solenoid Gas Valves
APPLICATION
The electrically operated V4295A, S and V8295A, S Solenoid
Gas Valves control the flow of natural and LP (liquefied
petroleum) gases.
INSTALLATION INSTRUCTIONS
FEATURES
• V4295A,S are used with 120 Vac controllers;
V8295A,S are used with 24 Vac controllers.
• Models available in Normally Closed and Normally
Open configurations.
• Normally Closed models, for safety shut-off
applications, consist of a direct on/off operator for
opening and closing of the valve.
• Normally Open models, for vent (double block and
bleed) valve applications, consist of a direct electric
on/off operator for closing and opening of the valve.
• Models are suitable for the control of gaseous fluids in
gas consuming appliances according to international
standards.
• Models have 1/4 inch NPT inlet and outlet pressure
taps.
• Models have inlet screen to protect the valve from the
entry of dirt.
These valves are used on atmospheric boilers, commercial
water heaters, roof-top make-up air burners, power burners
and boilers.
