FLS-R

Large-bore HP API 6A slab-style gate valve

Advantages

Simple, reliable gate and seat design that promote ease of field service and minimal spare parts inventory
Unique ball-screw design that allows for rolling friction in place of sliding friction
Bidirectional design that provides flow direction versatility and increased service life
Seal diameters and bearing areas of the seats that prevent trapping of pressure inside the valve cavity
Lower stem that balances pressure thrust on upper stem to reduce operating torque, which prevents body cavity pressure buildup during operation and provides position indication
Metal-to-metal stem backseat on both the balancing stem and valve operator stem for replacement of either stem seal with the valve cavity under pressure
Backseat that can be energized to isolate the stem seal stuffing box from line pressure and the grease fitting port used to test the backseat integrity
Two spring-loaded, pressure-energized, nonelastomeric lip seals for maximum protection against intrusion of particle contaminants into the valve cavity
Seals that improve gate and seat service life, prevent damage to the body seat seal face, and improve valve performance at very low pressures
Metal-to-metal sealing at the gate-to-seat and seat-to-body seals
Forged body
