Valves, Controls, Sight Glasses and Accumulators
Recognise the function and leakage exposure of common control and line components and their connections.
Prepare from scope to safe handover
Start with category and territory, build the underpinning science, then use a controlled technical and record sequence while reserving hands-on competence for supervised practical preparation.
Core concepts
Concept 1
Recognise the function and leakage exposure of common control and line components and their connections.
Exam cue: Identify the component's intended state, inspect caps, stems, seals, flare or brazed joints and supports, then compare visual evidence with operating behaviour.
Concept 2
Service valves, Schrader cores, pressure controls, indicators and gauge connections are frequent access or movement points and deserve focused inspection.
Exam cue: Keep qualification category, work territory and practical authority visible throughout the decision.
Concept 3
Accumulators and oil separators protect system operation but add vessels, joints and return paths that can deteriorate.
Concept 4
A component indication supports diagnosis only when the component is known to be serviceable and read under the intended condition.
Targeted study blocks
Scope
Know what this topic controls
Recognise the function and leakage exposure of common control and line components and their connections.
Method
Use a repeatable evidence sequence
Identify the component's intended state, inspect caps, stems, seals, flare or brazed joints and supports, then compare visual evidence with operating behaviour.
Boundary
Stop at the legal and practical limit
A component indication supports diagnosis only when the component is known to be serviceable and read under the intended condition. Do not leave temporary gauges connected or valve caps unsecured after service.
Risk pitfalls and guardrails
Do not leave temporary gauges connected or valve caps unsecured after service.
Guardrail: Check the current official source and stop when the task exceeds the qualification or practical boundary.
Do not treat historical handbook legislation wording as the complete current workplace rule.
Guardrail: Check the current official source and stop when the task exceeds the qualification or practical boundary.

Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
