• On older machines

• Used for higher speeds (A2-principle)

• Used for higher pressure

• 100 % sealing between inlet and outlet

• ATTENTION:

Do not mistake it for special multi-channel DXSA types designed for rotating stretch blow-mouling machines

DXSA (old standard design)

• Replaces obsolete standard design DXSA

• B2 principle (siphon pipe rotates along with rotor) • No wear at inner pipe

• For higher speeds

• For higher pressure

• Rotor not with shoulder but exchangeable rotor seal (counter face)

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):

For hot oil (generally)
