High temperature solenoid valve +200C
High temperature solenoid valve +200C
(OP)
I am looking for small direct acting soienoid valves for steam at low pressures. Orifice size 2mm to 5 mm.
I have used below valves with PTFE with some sucess.

Problem is valve may be subject to higher temperatures than 170C for short periods (1-3 sec) that may be detrimental to valve.
Function is to evacuate to athmosphere steam from a chamber that could be running at 600C . At the end of evacuation super heated gas and steam measured around 300C for short periods.
Without adding countermeasures to protect valve does anybody know of a relatively inexpensive valve that can take these temperatures.
Needs to be relatively fast ( less the 0.5 sec). Pressure (0-10 bar) normally (0-3 bar).
Normally open to evacuate.
Many thanks

RE: High temperature solenoid valve +200C
The valve construction for your conditions is no problem- the trouble is the solenoid actuation, which exerts so little force that it needs elastomers to have a hope of sealing.

Can anyone know a manufacturer of all metal solenoid valves that would be ecconomical for domestic products? 2-5 mm orifice.
So far all I have found is large industrial valves for plant and similar.
