Descripción del Producto
Cameron’s WKM gate valves are typically used for mainline and manifold valves in liquid pipelines. TFE seals on both faces of the WKM Pow-R-Seal Gate Valve ensuring drop-tight sealing even at low differential pressure, while metal to metal contact between the seals and gate mechanism provide fire safe shut-off. Optional all-metal seals are also available for service to +1,000F (+538C), where leakage rates comply with API 6D, Supplement 2.
Sixty years of worldwide service in oil, gas, chemicals, water, slurry, and multi-products applications has confirmed the Pow-R-Seal is the most trusted gate valve, especially where safety and reliability of sealing 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.
WKM Pow-R-Seal gate valves are the choice of liquid pipeline operators because they tolerate the wax, paraffin, abrasives, and multi-product flow that causes problems in other valve designs.
The WKM Pow-R-Seal 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 stem seal
- In-line, field repairable
- Certified fire safe to API 6FA, Bs6755, and ISO 10497
- Selected for corosive, erosive and aggresive pipeine service
