H 3 | the „3“ stands for vacuum valve
H3 vacuum valve
Why H 3?
• Used on steam heated textile dryers • Which are rather thin-walled
• Optional to H duo-flow versions
• Vacuum valve prevents damage of cylinders • e.g. implosion
• H3 joints are used when dryers do not have their own vacuum valve
• Standard sealing ring (synthetic carbon):
For steam and water , max. 250°C, 20 bar • (optionally also for hot oil: < 10 r.p.m and pressure < 2 bar)
• „W“ sealing ring (metal impregnated carbon):
