Steam Solenoid

Steam Solenoid

Steam Solenoid

(OP)
I am trying to locate a small diameter (1/4") valve for a pilot line of a steam regulator.  The possible process conditions are 320psig and 650 deg F (normally 130psig and 350deg F).  I've tried all the usual suspects and I can't find any manufacturer who can supply a controlled valve.  Any manufacturer ideas?  Its used for shutting off S/H steam flow to the valve head in case of equipment failure.

RE: Steam Solenoid

I do not know of a solenoid valve that will be reliable at your pressure and temperature.  However, an actuated ball valve may work (although smallest size is 1/2").  Look at, for example, Velan metal seated ball valve.

RE: Steam Solenoid

  We have a 1/2 inch solenoid steam valve which controls steam at only 50 psi and we find it necessary to renew the valve every  18 months approx due to failure of solenoid, despite everything the manufacturer says. I guess you will have a problem at your conditions. Cheers David W

RE: Steam Solenoid

I may be able to find one for you,
I will keep you posted.

RE: Steam Solenoid

probably not a good idea to implement the interlock that you've described. reliability is an issue.
