Gate Valve Design Features

Swivldisc® Wedge Gate Design

The Conval Swivldisc® wedge gate design employs a flexible disc which permits the seating surfaces to achieve perfect alignment, establishing a tight seal not possible with standard wedge gate valves.

Pressure Seal Bonnet

The simple and effective pressure seal bonnet provides ready access for servicing with no welds to cut or seal rings or gaskets to replace. The body-to-bonnet joint integrity is maintained through countless thermal cycles.

High-performance Packing System

The packing system delivers the best performance available. The one-piece gland with integral gland wrench is readily adjustable at any time. The fine finish of the stem and chamber combines with high-performance graphite packing to ensure long packing service life.

Single-piece Gland

In extreme environments, the simpler the design and the fewer the parts, the better. The durable single-piece stainless steel gland contributes to the longevity of the valve.

Axial-Loaded Packing System

The Axial design ensures tight concentricity, which eliminates side loading of the packing and minimizes wear forces on the trim components. This feature is critical for superior gate valve performance.

Pressure-Actuated Backseat

The Swivldisc® pressure-actuated backseat provides maximum valve integrity by ensuring a positive internal stop for the valve stem and disc assembly. The pressure actuated backseat also extends packing life by securely isolating the packing from the pressure when the valve is fully open.

Rapid In-Line Renewability

The Swivldisc® Gate Valve is much easier to renew than anything else on the market. The Swivldisc® Gate Valve line provides a modular solution to rising maintenance expenses. Low acquisition cost is not as important as low cost over the serviceable life of a valve. Maintaining a Conval valve is far easier and much less costly than replacing a competitor’s valve.
