ABM Large Pneumatic Control Valve With ABB V18345 V18346 Control Valve Positioner

Chinese Famous ABM large Pneumatic Control Valve with ABB V18345 V18346 Control Valve positioner

Chinese Famous ABM large Pneumatic Control Valve with ABB V18345 V18346 Control Valve positioner are designed with features for optimized pressure, flow, and process control. An optional drilled attenuator controls noise and vibration from high pressure drop liquids and gases. The splined shaft connection to the actuator reduces lost motion

Specification

Special features
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 Wuzhong 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.
