API 6D Through Conduit Flat Gate Valve
Through-conduit gate valves are designed as isolation devices to completely block the flow of media. They can handle temperatures up to 200°C. However, if employed for regulating or throttling, the manufacturer does not ensure tightness. These valves are equipped with a full-bore, piggable construction that maintains a flow resistance coefficient equivalent to the pipeline, making them ideal for use in long-distance pipeline systems.

TECHNICAL FEATURES
Floating Seat Structure: Features a floating seat design for smooth and effortless valve operation.
Ease of Operation: Allows for easy opening and closing of the valve.
Full Bore Design: Designed with a full bore for pigging and minimal flow restrictions.
Low Flow Resistance: Exhibits a very small flow resistance coefficient.
Self-Sealing: Ensures reliable sealing with zero leakage.
Automatic Cavity Pressure Relief: Automatically relieves pressure within the valve cavity.
DBB Function: Includes a double-blocking and double-bleed (DBB) function for enhanced safety and isolation.
Bi-Directional: Suitable for bi-directional flow with a preferred direction of flow.
