- 1 - 8th edition No. SS2-ADV100-0100 CV3000 Alphaplus series Top and Bottom Guided Double-Seat Control Valves (6 to 12inches) Model ADVB / ADVM OVERVIEW The CV3000 Alphaplus top and bottom guided double-seat control valves have a flow passage that allows fluid to flow smoothly and with minimal pressure loss. Valve plug shape implements design features that optimize flow and pressure balance around the plug, and improves the stability of control for a wide range of fluid conditions. The plug guide is supported at the top and bottom, and has a high resistance to vibration and abrasion. Valve body is light-weight, and employs a fixed guide structure for the bottom guide of the plug. For the plug and seat ring, a top-entry method improves ease of maintenance regardless of the valve action. Integral seat ring ensures identical seat-leakage performance (IEC Class IV) as single-seat valves. The valve also features a compact, but powerful, multi-spring actuator. Model ADVB/ADVM control valves are particularly applicable for high-pressure and high differential-pressure process lines where high dynamic stability and high reliability are essential. 1. Selection of Alphaplus Specifications Selection of control valves has traditionally required special knowledge and experience. However, CV3000 Alphaplus offers you more accurate product specifications, so that you can easily pinpoint the control valve that satisfies fluid specifications (such as flowrate, pressure, and temperature) at your plant and provides the functions you need.
