KE Series Through Conduit, Double Expanding Gate Valves The KE Series is an advanced API 6D designed gate valve that provides a tight mechanically activated seal.

1 KE Series Through Conduit, Double Expanding Gate Valves The KE Series is an advanced API 6D designed gate valve that provides a tight mechanically activated seal. It has double sealing, bi-directional sealing and dynamic mechanical sealing function, a full bore port, and is fully piggable. Main applications are offshore/onshore drilling & production, oil & gas transportation isolation, upstream gas compression isolation, hot steam, and oil tank storage. it can also be used for block and bleed applications.

Design Features - KE Series Full bore design, allowing for scraper, shot tap cutters and pigs. Negligible pressure drop. Fire safe design to API 6FA / API 607.

Stem packing can be replaced in-line in fully open and fully closed position after cavity pressure released from body vent drain plug.

2 Design Features - KE Series Full bore design, allowing for scraper, shot tap cutters and pigs. Negligible pressure drop. Fire safe design to API 6FA / API 607. Special top entry design, allowing for in-line maintenance. closed position. Stem packing can be replaced in-line in fully open and fully closed position after cavity pressure released from body vent drain plug. Automatic pressure relief system will release the over pressure in the cavity, protect the valve. Can be installed with pipe at any angle, vertical, horizontal, reverse position. Multi-operator types: handwheel, gear box, pneumatic, electric, etc. Dust proof plate on yoke. Valve has back seat and stem blow-out proof design. Seats may be lubricated to promote long life, minimize operating torques, or effect a seal in an emergency. Especially suited for Pig Traps isolation. Double Block and Bleed Performance. For size 8" and above, the gate and segment are connected with lever mechanisim For size 2" to 6", the gate and segment are connected with a spring Pressure Relief Provisions Because expanding gate valve is utilizes a dynamic bi-directional sealing valve, pressure will be trapped in the valve body cavity when the valve is in the full open or closed position. High internal pressures can result from the thermal expansion be released by the body safety relief system to either external piping or to the inlet side of the valve. (see figure, left) Conforms to API 6D. Page 2

Working Principle of the KE Series Double Expanding Gate Valve Seal Closed In the fully closed position the segment has engaged with an end-stop and the gate is wedged downward, expanding the segment

Valve is in sealed position Mid-Travel During travel towards open or close, the gate slides across the wedge angle of the segment, collapsing the assembly so that it travels freely between the seal

3 Working Principle of the KE Series Double Expanding Gate Valve Seal Closed In the fully closed position the segment has engaged with an end-stop and the gate is wedged downward, expanding the segment and gate so that they form a tight mechanical closure against the upstream and down - stream seats. Valve is in sealed position Mid-Travel During travel towards open or close, the gate slides across the wedge angle of the segment, collapsing the assembly so that it travels freely between the seal faces. The lever lock gate central - izer holds the mechanism in the neutral position until closed and fully open position expansion is required Fully Open When the bore in the segment is aligned with the conduit bar, an end-stop prevents further travel and the gate slides across the wedge angle, expanding the gate from the body The lever arm is held parallel to the gate faces by the skirt plate, while the assembly is moving through its stroke. Near end-oftravel, the skirt allows the lever to tilt. The gate and segment slide against their angled faces, creat - ing the expanding seal action. In segment are mechanically se - cured in place. The skirt plates are guide rails, align the gate and segments with the seat. Page 3
