NEW! Larger size steam whistle valve in 1/8" NPT thread. Valve only, add your own whistle. Designed with the live steam railroader in mind. Click for information on model pipe threads.
On the fourth or fifth steam up the whistle valve stuck wide open even though the lever and plunger were working and the plunger was returning to the closed position. Something inside broke also causing it to vent steam out from where the plunger goes into the body of the valve. Very disappointing as everything else I have purchased from PM research has been perfect!
Great. Best value whistle valve on the market.
