Controlled duty
Define monitored conditions, valve fail position, response time, downstream isolation, divert destination, recirculation impact, seal leakage, reset and saleable-product boundary for every underprocess scenario. The review must also reconcile critical temperature, flow and pressure conditions with valve construction, position and response time across normal, transition and fault conditions.
- Critical temperature, flow and pressure conditions
- Valve construction, position and response time
- Required result and acceptable operating range
