CEGV

The Valbart CEGV compact expanding gate valve is a fabricated body-expanding gate valve manufactured andtested in accordance with API 6D, latest edition. The compact expanding gate design features a full-bore diameter, with a compact, non-through conduit design providing a compact and lightweight valve package. Valbart expanding gate valves are engineered to achieve tight shutoff at high and/or low pressures in liquid or gas services. The expanding gate and segment design provides a high-integrity seal for a variety of critical applications, while affording lower operating friction.

The expanding gate and segment design of the CEGV is designed to push against the seats for positive sealing, even at low pipeline pressures

Mechanical action of the gate expansion does not require pipeline pressure to assist in the sealing, providing a positive seal at low pipeline pressures

Wedging action of the gate/segment multiplies the loading against the seats, creating high seating forces that are unaffected by higher pipeline pressures

On opening stroke from the closed position, the control arm engages the guide plate and pivots, causing the gate and segment to un-wedge and contract inward, away from the seats

CEGV engineered bore sealing mechanism utilizes a soft seal enclosed within a metal-to-metal seat providing positive uncompromising isolation for severe/heavy-duty applications

The wall sections and ribs have been engineered using state-of-the-art finite element analysis for optimizing strength over weight and ensuring material is placed where needed

Compact installation with associated weight savings over the through conduit design, where there are no requirements for pipeline pigging
