DPT-CB010
The ABB DPT‑CB010 is a dual‑power automatic transfer switch (ATS) control module designed to provide automatic switching between two electrical power sources (e.g., utility mains and a generator) in low‑voltage distribution systems. It forms part of ABB’s CB‑class automatic change‑over switch series, enabling automatic load transfer when the primary power source fails and automatic return once the primary source is restored. The unit combines control logic with protective switching functions suited for applications that require high continuity of power, such as commercial buildings, industrial facilities, and critical electrical loads.
FISHER™ BAUMANN™ 24000C
Technical Parameters
General
Model: Fisher Baumann 24000C Control Valve
Type: Pneumatic Actuated, Cage-Guided Globe Valve Body
Primary Application: High-pressure drop, anti-cavitation, and noise attenuation services.
Valve Body
Size Range: 1/2 inch to 4 inches (DN 15 to DN 100)
Pressure Class: ANSI 150, 300, 600, 900, 1500, 2500 (depending on size and construction)
End Connections: Flanged (RF, RTJ), buttweld, socket weld, or threaded.
Body Materials: Carbon Steel (WCC), Stainless Steel (CF8M/316), Alloy 20, Duplex Stainless Steel, and other alloys.
Actuator
Type: Spring-and-Diaphragm Pneumatic Actuator.
Action: Fail-Close (Air-to-Open) or Fail-Open (Air-to-Close) configurations available.
Spring Ranges: Multiple standard spring ranges are available (e.g., 0.2-1.0 bar, 0.4-2.0 bar, etc.) to match available air supply and required thrust.
Trim & Performance
Trim Type: Baumann "C" Multi-Stage, Anti-Cavitation Trim. The flow path is split into multiple stages, each dissipating a portion of the pressure energy to prevent cavitation.
Flow Characteristic: Modified linear or equal percentage, inherent to the multi-stage cage design.
Leakage Class: ANSI Class IV (standard metal seat). ANSI Class V or VI (soft seat) is available for applications requiring tight shutoff.
Noise & Cavitation Control: Significantly reduces noise (typically by 10-20 dBA) and eliminates cavitation damage compared to standard single-orifice valves.
Flow Capacity
Cv Range: Available in a wide range of Cv values, selected by choosing the appropriate trim size and number of stages for the specific application. Exact Cv values are determined by the trim designation (e.g., C-1, C-2, etc.).
Pressure & Temperature
Max Inlet Pressure: Up to ANSI Class 2500 rating (e.g., ~420 bar @ 100°F / 38°C for Class 2500).
Temperature Range: Standard packing from -29°C to 232°C (-20°F to 450°F). High-temperature designs are available for services up to 538°C (1000°F).
Options & Accessories
Positioner: Fisher FIELDVUE DVC6200 or other pneumatic/high-performance positioners can be mounted.
Limit Switches: Solenoid valves, proximity switches, and other accessories.
Air Sets: Filter regulators (Type 67SR) can be mounted directly on the actuator.
Packing: Standard V-ring, low-emission live-loading, or bellows seal options.
