Key Parameters & Specifications Parameter / Feature Category Description Product Name Fisher™ Baumann™ 24000S Pneumatic Actuator Type Spring-and-Diaphragm, Low-Friction, Rotary Actuator Primary Function To provide precise rotary torque for modulating control of quarter-turn valves (e.g., V-notch ball valves). Actuator Type Spring-Return (Fail-Safe). Input Signal Standard: 3-15 psig (0.2-1.0 bar) or 6-30 psig (0.4-2.0 bar). Supply Pressure Typically up to 100 psig (7 bar). Housing Material Glass-Reinforced Polyamide (Composite) for corrosion resistance and light weight. Torque Output Provides precise, high-resolution torque. Exact values depend on the actuator size and supply pressure. Standard Rotation 90° quarter-turn. Action Field-reversible between direct and reverse action. Typical Fail-Safe Action The "S" model is commonly configured as Air-to-Close, Spring-to-Open (Fail-Open). Temperature Range -20°F to 180°F (-29°C to 82°C) with standard components. Mounting Designed to mount to valves with ISO 5211 mounting pads. Uses a standardized mounting kit system. Accessory Ports Prepared for the installation of accessories such as: • Limit Switches • Solenoid Valves • Positioners (e.g., Fisher 3582 or a FIELDVUE DVC)
