Design benefits

• Field replaceable thick elastomer sleeves are easily replaced without disassembling the valve
• Sleeves are available in a variety of materials to handle abrasive and corrosive applications
• Full port flow reduces pressure drop and turbulence, thus minimizing wear
• Bi-directional shut off
• 100% bubble-tight shut off
• Packingless design; no gate or stem packing
• Open bottom allows for the purging of large solids, and solids in high concentration
• Yoke design allows fitting for all designed actuators
• No seat cavities where solids can collect and cause gate interference
• May be used in wet or dry application
• Flush control option allows for periodic cleaning of the lower discharge vent and allows flushing as needed

Design 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 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
