- Zero leakage, bi-directional tight shut-off
- One single piece seating installed on the valve body (available on the disc as alternative)
- Interchangeable and adjustable seal ring
- Disc or body mounted rubber seal or metal ring
- Self-cleaning seat
- Shaft protected from aggressive media
- Welded, bolted or integral seat
- Self-lubricating bearings
- Corrosion resistant shaft bushing
Benefits of HP Series
