Graham-White's 353 Series
of manual horn valves allow an engineer great control over signaling
a locomotive's horn that electronic solenoid valves cannot provide.
Several metering options are available in the 353 Series: 12 SCFM,
24 SCFM, and 30 SCFM. We can provide you with a valve that
best suits your horn, as different series and models of locomotive
horns react uniquely to various air flows. A 70 SCFM non-metering
valve is also available. The 353 Series uses a common body
and operating lever that allows for easy maintenance.
Optional operating levers
are available, and we can customize your valve to allow for pull
cord operation that is often found in older locomotives.
