Features
Excellent Flow Control: The splined shaft to actuator connection, double power-end bushing assemblies, and trunnion guiding, all provide improved dynamic control.
Aerodynamic Performance: Up to -20 dBA acoustical attenuation can be achieved for the V280 with Aerodome within a single stage construction. Dual-stage construction can provide up to -25 dBA attenuation.
Improved Service Life: The attenuator is not part of the seal assembly. The seal wipes the ball surface, not the attenuator, promoting increased service life.
Construction Versatility: All parts are interchangeable. The valve construction can be altered by adding/removing a dome attenuator and/or seal. This allows for flexibility to meet your changing demands
Thoroughly Tested: Valve construction cycle and flow tested in laboratory subject to full CL900 pressure drops and beyond full expected life
Design Simplicity: Tailpieces are the same no matter what seal and dome quantity is chosen.
Sour Service and Sour Crude Oil Capability: Standard construction materials comply with NACE standard MR0175/ISO 15156
Heavy Duty Trunnion: The ball trunnions are designed for demanding applications requiring long service life, with a reduction in maintenance time and costs.
Broad Hydrodynamic Applications: Single and dual stage attenuators for the V280 with Hydrodome may be provided for a varying range of applications. A KC value of 1.0 is achievable depending on service conditions
Flexible Applications: The attenuator is active throughout the ball rotation for very demanding services or characterized attenuator is used to match the service conditions
Tight Shutoff: Self-adjusting seal(s) that are pressure assisted provide tight shutoff for long reliable service. The design incorporates a heavy duty S31600 stainless steel carrier that retains the composition seal for full-rated pressure drop service.
