RAVEN™
Description
Every RAVEN™ trim is custom designed to meet the needs of the toughest liquid, steam and gas services in the power and process industries.
The RAVEN™ Control Valve incorporates a unique advanced design that is superb at rapidly reducing flow velocities, resulting in valves that provide quiet, non-cavitating and non-erosive service. Ultimately, each RAVEN™ trim is specifically designed to provide the finest severe duty valve service by: Reducing and Attenuating Velocity, Erosion and Noise.
Features
- Tight Shutoff: Equipped with various plugs (unbalanced, balanced, tandem, etc.) RAVEN™ can provide shutoff classes ranging from ANSI/FCI Class IV to VI and MSS-SP-61.
- Resists Plugging and Galling: An internal pressure balancing groove on each disk ensures equal pressure distribution eliminating the potential for side loading and galling of the plug. Bypasses in the flow paths allow entrained debris to clear the main fluid path.
- Easily serviced: Quick-change design with no threaded or welded parts. Seat ring is a separate replaceable item.
- Characterization: Able to provide application specific performance response for optimum system performance.
- Quieter: Size for size RAVEN™ trim has been proven quieter than the stacked disc trims of our competitors in extensive laboratory testing.
- Adaptable Flow Direction: Flow can be either over or under the seat depending on the fluid, the service and in some instances, the piping configuration.
- Retrofits/Upgrades: Readily tailored to fit valves previously supplied without RAVEN™ trim Copes-Vulcan or other brands.
