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.

These valves are used on atmospheric boilers, commercial 

water heaters, roof-top make-up air burners, power burners 

and boilers.

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.
