| Routed pipepipe_run | A polyline swept as cylinders with a slightly oversized sphere at every bend. NOTHING on this sheet prints a size (Note 2), so every diameter is a sketch choice: ~1.5" process, small-bore air/sample, a thin signal cable. 16 runs — suction, discharge, recirc, sample, air, drains |
| Valve bodyvalve_body | Two truncated cones nose-to-nose (a bowtie), companion flanges each side, stem and gland on top. Typed from the DRAWN symbol, per this sheet's own legend: plain = gate, centre dot = globe, open circle = ball. 6 bodies — HV-101/102/103/111, sample ball, CV-101 |
| Handwheel / leverhandwheel, lever_handle | Red ring with crossed spokes for rising-stem valves; a red quarter-turn lever with a grip tip for the ball sample valve; a side-mounted wheel for the HV-111 drain under V-110. 5 — one per hand valve |
| Check valvecheck_valve | Fat barrel + flanges + a small cone riding on top pointing with the flow. Used for CV-101, because the sheet DRAWS the check-valve legend symbol there (arrow + dot + bowtie), with no actuator. 1 — CV-101 (tag/symbol tension recorded in COVERAGE.md) |
| Relief valverelief_valve | Angle pattern: inlet flange, body drum, spring bonnet, cap, side outlet, plus a short vent tail. Sits straight on V-110's top head, as drawn. 1 node(s) — PSV-110 |
| Vesselsfilter_vessel, vessel_vertical, exchanger | F-101: pot + domed top + quick-open closure + drain plug on a leg. V-110: barrel + dished heads on three legs. E-101: shell + channel heads + nozzles on saddles (shell-and-tube is a sketch choice — the symbol is generic). F-101 (?), V-110, E-101 (?) |
| Machinespump_body + pump_motor, compressor package | P-101: baseplate, volute with suction/discharge nozzles, TEFC motor M-101 with fins and terminal box, coupling guard. C-101: crankcase block, finned cylinder head, drive motor, belt guard. P-101/M-101, C-101 |
| Instrumentsinstr_stem + instr_gauge | Thin stem off the pipe or shell, dial can with bezel on top. PI-101 also carries the sheet's one signal line, to the PLC/HMI panel. 3 gauges — PI-101, PI-102, PI-110 |
| Skid & sitechannel frame, stanchions, cabinet, boundary_marker | Structural channel frame + chequer deck + leveling feet (~2.3 m — the machine is a training skid roughly 2 m long). Green cone arrows wherever the sheet hands a line off this section. 4 off-sheet arrows |
