Valve sizing & control 0.5.0 Free during launch

Valve OTS 电解槽调节阀仿真台

Size the valve against a simulated plant, not a spreadsheet.

A dynamic bench for multi-stack electrolysis: model the separation system, step the load, compare Cv, then replay the run on an operator console.

Chart of a simulated valve-sizing run: load and valve position trends, four KPI figures and three small trend panels.
The shape of a recorded run. Illustrative figures; not a client case.

01What's inside

The specifics, with numbers.

The things a general-purpose tool does not do.

01

The reference case is concrete

4 × 1000 Nm³/h electrolysers feeding one 4000 Nm³/h separation system — the question this bench was built to answer.

02

100 ms cycle, 1×–60× time

The OTS engine controls and records every 100 ms; accelerate a shift into minutes without losing the record.

03

Eight scenario types

Load step, pulse, ramp, start/stop, wide load swing, pressure setpoint step, downstream disturbance and H₂ routing switch.

04

Every run archived

A 100 ms CSV, parameter snapshot, event JSONL and summary in their own folder, with history replay and CSV export.

05

Tune while it runs

Online PID tuning and auto-optimisation, static Cv recommendation and dynamic Cv optimisation.

06

Two ways in

Scenario check for comparing Cv options; operator mode for driving load setpoints live. A 3.8 MB macOS app or a 548 KB offline HTML file.

Language

Documentation and interface for Valve OTS are Chinese-first, because the buyer for this kind of study usually is too. The model and the reference case are the same in either language.
