1. 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 corrosionresistant materials.

2. Reliable sealing. Bonnet gasket fully confined to prevent creep.

3. Additional stem seal for emergency operation and blowout protection by standard back seat as well as back-up gland packing made of pure graphite.

4. 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.

5. Easy to repair due to corrosion-protected bolts/screws and nuts
