Key features/benefits
- Unibody design and rugged heavy duty construction ensures long valve life and greater reliability
- Flexible two-piece sleeve system allows valve to cycle in heavy slurries without sticking
- Sleeves are easily replaced without disassembling the valve
- Replaceable upper seal design is not only packingless, which eliminates the need for periodic adjustment, it is also a self-lubricating system and is rechargeable without valve disassembly (sizes 2” through 16”)
- Full port design reduces pressure drop and turbulence
- Open bottom allows for the purging of large solids and solids in high concentration
- Bi-directional shutoff
- Wafer style saves pipeline space
- Sleeves are available in a variety of materials to handle abrasion and chemical applications
- Flushing plate option allows for periodic cleaning of the lower discharge vent and allows flushing as needed
- Enclosed bronze stem bushing with a protected grease chamber means less operating force after long dormant periods
- Upper stem protector and optional protective lower stem cover prevent external contamination
