Improve safety performance with ensured reliability

Double Expanding Gate Valve

As the OEM of Cameron, our workshop has completed plenty of projects with Cameron design.

The double expanding gate valve is one of the most trusted gate valves, especially where safety and seal reliability are critical.

The positive, mechanical seating force of the lock-in-place seals holds with zero leakage through conditions of vibration, pressure change, and temperature excursion. The rigid, cast steel body resists pipeline bending moments.

TFE seals on both faces of the valve provide drop-tight sealing even at low differential pressure, while metal-to-metal contact between the seals and gate mechanism provides fire-safe shutoff. Optional all-metal seals also are available for service up to 1,000 degF [538 degC], where leakage rates comply with API Spec 6D, Supplement 2.

Cameron’s Pow-R-Seal gate valve is the choice of liquid pipeline operators because it tolerates the wax, paraffin, abrasives, and multiproduct flow that causes problems in other valve designs.

The gate valve provides these specific advantages resulting in reliable performance and long life:

Protection of seat faces
Smooth, continuous conduit for flow
Tight mechanical seal and double block-and-bleed capability
Fugitive emissions-tested SLS spring-loaded lip seal
In-line, field repairable
Certified fire-safe to API Spec 6FA, BS 6755, and ISO 10497
Selected for corrosive, erosive, and aggressive pipeline service
