FLS-R Large-Bore HP API 6A Gate Valve

FLS-R Large-Bore HP API 6A Gate Valve

Overview

The FLS-R gate valve is our premier gate valve that utilizes the latest technology in component design and materials. The FLS-R has a unique ball-screw and lower balancing stem mechanism that greatly reduce the torque required for operation. Field-proven performance, combined with ease of use, makes this valve ideally suited for large-bore and high-pressure environments in production, manifold, and fracturing applications.

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
