Excellent Throttling Performance—The splined ball to shaft connection, 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 V260A within a single stage construction. Dual-stage construction can provide up to -25 dBA attenuation.
Improved Service Life—The attenuator is an integral part of the seal assembly. The seal wipes to ball surface, not the attenuator, promoting increased service life.
Trim Versatility—Key valve components, such as valve body, ball, shaft and bearings, are interchangeable between the Design V260A, V260B and V260C. This feature allows you to reduce your spare parts inventory and maintenance time.
Sour Service and Sour Crude Oil Capability—Optional materials are available that comply with NACE Standard MR0175-2002.
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.
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, dual, and three-stage attenuators for the V260B 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 a characterized attenuator is used to match the service conditions.
