DVGW course modules
The course material as step-by-step slide modules, each with quick checks and a link to the matching practice test. Module 1 is free to try; modules 2–9 are for course participants — no password? Request one at rkbf.pro.

PRMS explained — pressure reduction & metering station
Click any component of the station to zoom in and see what it does, the DVGW G 491 design rules and what to check in maintenance — or follow the guided tour from inlet to outlet.
Reflux 819 regulator — how a pilot-operated regulator works
Change the downstream flow and watch the loop: the outlet pressure deviates, the pilot changes the motorization pressure, the piston moves and the outlet pressure returns to the set point. Zero flow shows lock-up.
Gas production processing training
Interactive 3D models of an offshore gas platform — separation, the inlet train, boarding valve and choke, TEG dehydration, the MEG loop and MRU, heat medium, power generation, control and safety systems, the platform structure and shutdown / restart — each with a guided tour and self-check quiz. For course participants: you need the password you were given.
Tool 1 Pressure diagram — setpoint check
Checks that the tolerance bands of a station's devices are correctly staggered and do not overlap, per EN 334 / EN 12186. Choose the configuration that matches the station.
Tool 2 Safety-device count (G 491 / EN 12186)
Determines the minimum number of safety devices a pressure-regulating station requires, from the upstream and downstream pressure levels.
Tool 3 Cg — regulator flow coefficient (EN 334)
Computes the flow coefficient Cg of a gas pressure regulator and identifies the flow regime (critical vs sub-critical). Pressures are absolute.
Engineering tools based on the CH4 Engineering course sheets (EN 334 / EN 12186).
Assessment — candidate details
You will be asked questions drawn at random from the full bank. To complete the assessment you must answer two questions correctly; an incorrect answer is followed by another question. Your details and your answers are recorded.
Fields marked * are required. Your answers are submitted when the assessment finishes.
Examination — candidate details
A full examination of 57 questions, drawn at random from the whole bank so that every candidate receives a different paper. You may answer in any order and change answers until you submit. You have a bank of 10 hints to use across the paper — a hint narrows the options and explains the point being tested. Results are recorded.
Fields marked * are required. Once you begin, the paper is fixed for this attempt.
EN 12186 — maximum pressure levels
These are maximum values: a set point at or below the limit is OK, above it is not.
