Description
Main Applications
– Process engineering
– Chemical industry
– Petrochemical industry
– Sugar industry
– Heat recovery systems
– Boiler feed applications
– Nuclear power stations -
Advantages
– High functional reliability and long service life
- – Two-piece stem. Burnished, non-rotating lower stem makes for minimal wear and long service life of the gland packing.
– Hard-faced valve seat made of wear and corrosion-resistant materials.– Leak-proof and easy to service. The double-walled bellows is welded to the stem at the lower end, and to the intermediate piece at the upper end. No vibrations transmitted from valve disc to bellows. Valve disc and bellows assembly inexpensive to replace.
– Reliable sealing. Bonnet gasket fully confined to prevent creep.
– Additional stem seal for emergency operation and blow-out protection by standard back seat as well as back-up gland packing made of pure graphite.
– Reliable shut-off due to tapered valve disc with angled seat/disc interface. Can also be used for contaminated fluids thanks to self-cleaning properties.
– Easy to repair due to corrosion-protected bolts/screws and nuts -
