Dewrance 1/4" Valve No.3000
 

Wanted Dewrance globe valve reference no. 3000 with nickel alloy valve and seat, valve size 1/4" fittings. This is for the blower valve on my Garrett wagon which is fed with superheated steam; this cuts through normal valve seats very quickly. Suggestions for alternative valves with renewable seats welcome.
Please send privae message.
Thank you

Crane will have an alternative I would think. Not sure of ref numbers though.

Michael, would it not be possible to take the steam for the blower from a none superheated supply?

Thank you for your suggestion Donald, yes, that would be a practical solution but I am trying to replicate what Garretts did. If I move the valve to the wet steam side of the superheater it won't be as easily accessible. The alternative would be to make an additional tapping in the boiler.

Michael.

Thank you Anthony, I will have another look at what Cranes have to offer if I can't find a Dewrance valve.

I had a brief google on this , and there appear to be such valves made , but they look as though they may be expensive , being very thoroughly engineered .

this is a section of the Dewrance catalogue listing their 3000 and 3000N renewable seat stop valves. also a description of the nickel alloy.http://www.tractiontalkforum.com/pic...ictureid=32910 http://www.tractiontalkforum.com/pic...ictureid=32909 http://www.tractiontalkforum.com/pic...ictureid=32908 http://www.tractiontalkforum.com/pic...ictureid=32907
