Technical Specifications Valve supply: 24 V DC ±10%; Valve control signal:4–20mA; SPM-D2-11: speed monitoring, frequency input; Operating pressure:0.4–10 bar(g); Operating temperature:-30 °C ~ +120 °C; Enclosure:IP65.
Functional Features Integrated gas valve and speed detection module; LVDT closed-loop valve control; engine speed monitoring and overspeed alarm; combined diagnostic function.
Application Scenarios All-in-one gas genset governing system, cogeneration unit speed + fuel control integrated package.
Performance Parameters Valve flow linearity:±1.8% FS; Speed measurement accuracy:±0.1% FS; Valve response time:<20 ms.
Material Composition Aluminum valve body; stainless steel valve internals; FKM seals; LVDT sensor; SPM-D2-11 electronic module, metal housing.
Structural Characteristics Inline proportional gas valve, separate SPM-D2-11 speed electronic module, matched wiring harness.
Working Principle 8440-2165 valve controls gas fuel flow via 4-20mA and LVDT feedback. SPM-D2-11 collects engine speed signal, provides speed feedback and overspeed protection signal to governor controller.
Installation Requirements Install gas valve inline; mount SPM-D2-11 in control cabinet; connect speed sensor wiring, valve power and signal cable; calibrate valve and speed channel.
Usage Notes Shield wiring for speed signal; check speed pickup gap regularly; maintain gas medium cleanliness for valve.
