FlowBiz Exports Conduit valves (6D gate valves) are engineered to use line pressure force for tight mechanical sealing upstream when high differential pressure occurs. Internal springs achieve low-pressure sealing as they help push seat rings against the gates.
These bi-directional, double block-and-bleed slab gate valves are through conduit, piggable, and top entry. Suitable for transportation pipelines for gas, crude oil, and oil products, all valves are available in various materials and configurations to meet your project requirements.
BENEFITS
Chevron-style polytetrafluoroethylene (PTFE) packing for long-lasting, trouble-free stem sealing
Seats to ensure low- and high-pressure sealing and body cavity self-relief
Stem injection fitting for secondary sealing
Smooth, electroless nickel-plated slab for bubble-tight sealing and low operating torque
Seat injection fitting with internal check valve for emergency sealing
Drain valve for block-and-bleed function and seat integrity verification
Valve serialization for complete traceability
Stem design with internal stops to prevent over-track of the slab (no adjustments required)
Secondary metal-to-metal sealing for fire-safe requirements
