API 6A FLS-R Gate Valves

FLS-R Gate Valve
 The Oilman FLS-R Gate Valve was designed for use as a manual valve in high-pressure, lage bore applications. This valve incorporates a lower balancing stem and unique ball screw mechanism for ease of operation in the field. The FLS-R is value- engineered for reliability, low torque, ease of operation and service. The FLS-R has many of the same features as the FLS  including the gate and seat design.
Features and Benefits

• Bi-directional design provides flow direction versatility and increased service life.
• Positive metal-to-metal sealing (gate –to-seat and seat –to –body).
• Simple, reliable gate and seat design promotes ease of field service and minimal spare parts inventory.
• Two spring-loaded, pressure energized, non-elastomeric lip-seals between each seat and body assist in low pressure sealing. They also protect against intrusion of particle contaminants into the body cavity and seal areas.
• Lower stem balances pressure thrust on upper stem to reduce operating torque, prevents body cavity pressure build-up during operation, and provides position indication.
• Spring-loaded, pressure energized, non-elastomeric stem seal covers full range of pressures, temperatures, and fluids.
• Pressure-energized metal-to-metal bonnet seal.
• Either stem can be backseated to allow stem seal replacement with valve under pressure.
• Grease injection fittings located on the downstream side of the stem and the balancing stem backseat for safety.
