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.
Stem seal design covers full range of pressures, temperatures, and fluids encountered in wellhead and manifold service.
Metal-to-metal bonnet seal, (pressure energized 10,000 psi WP and above).
Stem can be backseated to allow stem seal replacement with the valve under pressure.
Grease injection fitting located downstream of stem backseat for safety. Fitting located in bonnet, eliminating body penetration.
Bearing cap grease fitting allows positive bearing lubrication.
Easy closing and sealing without excessive torque.
