Ideal for production brazing and welding applications, Smith’s GASAVERS
™
can help you realize huge savings
by eliminating wasted gas during torch start-up / shut-down and between flame applications. Also saves time by
eliminating repeated torch adjustment. The GASAVER
™
gives you a safe place to temporarily put your torch and is
used by America’s largest production plants. Torch flame is automatically extinguished when torch is not in use.
Simply pass torch over pilot flame to re-light.
WDW100
Standard GASAVER
™
for use with propylene gas and oxygen. Equipped with pilot light.
WDW101
For general use on all types of acetylene and oxygen operations. GASAVERS
™
can be installed in any
convenient location on the line between regulators and torch. The closer the torch, the greater
the savings in oxygen and acetylene. Equipped with pilot light.
WDW103
Equipped with separate pilot fuel inlet for use
with low pressure gas with injector type
torches. Separate source of high pressure
pilot gas required. May also be used with
hydrogen gas, however propane or natural gas
is recommended to supply the pilot light.

Standard GASAVER
™
equipped with
Pilot Light for use with propane or
natural gas at 4 PSI or more.

GASAVER™ - Save Money, Save Time & Improve Safety
Reverse flow check valves are an important part of any oxy/fuel system. Without check
valves, reverse flow of oxygen and fuel gases can occur when a tip becomes clogged, or
when one cylinder empties during use allowing the higher pressure gas to back up into the
other hose and into the regulator, thereby creating conditions which could lead to a
regulator explosion. Smith’s reverse flow check valves close automatically when outlet
pressures drop below 1/2 PSIG, preventing reverse flow of gases.
