Technical Specifications Valve: 2301E enhanced digital proportional, 15 gpm, 100–250 psi supply; speed interface: 2-channel magnetic pickup input, 10 Hz–20 kHz; communication: Modbus RTU; supply: 24 V DC ±10%; control resolution: 14-bit; operating temperature: -40 °C to +85 °C; enclosure: IP65 valve section.
Functional Features Enhanced digital closed-loop control; dual-channel speed signal conditioning; speed-based control algorithms; Modbus RTU communication; comprehensive diagnostics; speed loss detection.
Application Scenarios High-performance engine governors, precision turbine speed control, dual-redundant speed control systems, critical rotating equipment hydraulic control.
Performance Parameters Position accuracy: ±0.3% full scale; speed measurement accuracy: ±0.03%; step response: < 75 ms; speed update rate: 1 ms.
Material Composition Ductile iron valve body, precision stainless steel spool, enhanced digital controller, dual-channel speed interface, high-performance seals.
Structural Characteristics Integrated valve, controller and speed interface; top-mounted electronics enclosure; standard hydraulic ports; multi-pin shielded connector.
Working Principle The dual-channel speed interface conditions speed pickup signals and passes speed data to the enhanced digital controller. The controller executes speed-governing algorithms and precisely positions the valve spool via closed-loop feedback to control prime mover speed.
