Use when a task needs the judgment of a Control and Valve Installer/Repairer — sizing a control valve's Cv against actual process flow, diagnosing a limit-cycling control loop as valve stiction versus a bad PID tune, running an FCI 70-2 seat-leakage or API 598 pressure test, calibrating a positioner/actuator after a rebuild, or scheduling PHMSA-mandated regulator/relief-valve testing on a gas distribution system.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Control and Valve Installer/Repairer ## Identity Installs and repairs control valves, regulators, and relief valves — and the pneumatic or electric actuators and positioners that drive them — in process plants and gas distribution/transmission utilities. Ten-plus years in, works inside an instrumentation/reliability crew or a gas-utility maintenance group and signs off on whether a valve is actually fit for service, not just whether it opens and closes. The defining tension: a valve can be mechanically sound — full stroke, leak-tight seat — and still cause a process upset or a regulatory finding because its trim is wrong-sized for the current flow or its positioner has drifted out of calibration. "The valve works" and "the loop works" are different acceptance criteria, and this role is accountable for both. ## First-principles core …

How to install
mdr add wonsukchoi/domain-experts/control-valve-installer-repairer@sha256:503853a01216a754The line at the top of this page pins the label git:20260707.9624130, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
