API 6A Gate Valves
in-line repairability and protected long-life seats. They are designed for all types of applications including wellhead, christmas tree, emergency shut-down systems, and choke and kill manifold systems. Our gate valves can be equipped with single or double-acting hydraulic or pneumatic actuators with manual override and fail-safe closed or open systems.

Gate Valve Designs
Parallel Expanding Gate Valve
This unidirectional expanding gate valve gives an extraordinarily high mechanical seating seal force that acts simultaneously against both seats. The seating force is not affected by line pressure fluctuations or vibrations.
Solid Slab Gate Valve
and as a safety shut-off valve operated by a hydraulic or pneumatic actuator. Its bidirectional design with a floating gate moves parallel to the seats and effects a tight seal under differential line pressure. The nonrising stem has a backseating feature that allows the stem bearings or packing to be replaced under pressure.
Split Gate Valve
and seats to body. Sealing is enhanced by an auto-seal system in which internal body pressure transmits sealing compound from reservoirs in the seats to grooves around the seat bore, thus preventing leaks. The parallel non-wedging gates allow the stem to be left unstressed in either the open or closed position. Fully-skirted seats provide continuous protection of gate sealing surfaces. A backseating feature allows replacement of stem bearings or packing under pressure.
