Predictika · Compressed air filter/regulators

An AI sales agent's filter/regulator order, checked before it goes out

An AI sales agent prepares an order for an Excelon B73G filter/regulator for a compressed air line: port size and thread, adjustment, drain, bowl, element, outlet pressure range, service conditions and the accessories that go with it. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the public Norgren datasheets and returns a verdict, every reason and the temperature limit it computed.

Scope: Norgren Excelon B73G general purpose filter/regulators, G1/4 to G1/2 and 1/4 to 1/2 PTF: ordering key options, bowl limits, outlet pressure ranges and compatible accessories. See everything this validator covers

This validator models the Excelon B73G filter/regulator as described in the public IMI Norgren datasheets en 8.180.300 (B73G, 3/19) and en 8.210.300 (B72G, B73G and B74G, 01/26), not just the scenarios shown below.

  • Ordering key — port size (1/4, 3/8, 1/2 inch), ISO G or PTF thread, knob or T-bar adjustment, manual or automatic drain, transparent, metal or guarded bowl, 40 or 5 micron element, with or without gauge, relieving or non-relieving diaphragm.
  • Outlet pressure range — 0.3 to 4, 0.3 to 10 or 0.7 to 17 bar; the set pressure must lie inside it, and the 17 bar range needs the T-bar and the metal bowl.
  • Service conditions — inlet pressure against the bowl limit (transparent 10 bar, metal 17 bar), ambient or media temperature against the limits for the bowl and the gauge version (transparent 50 C, metal 80 C, with gauge 65 C), minimum air flow to close the automatic drain, and dry air below 2 C.
  • Accessories — Quikmount pipe adaptor matched to port size and thread, Quikclamp at a port, R1/8 or 1/4 NPT gauges matched to the thread, service kit matched to drain and element, panel nut for panels 2 to 6 mm, shut-off valves.
  • Items a person confirms — non-relieving diaphragm and neutral gases (the two datasheets differ), the guarded bowl above the transparent-bowl limits (not stated separately), PTF shut-off valve part numbers (the sheet lists inconsistent port codes), and dry air below 2 C.

Any B73G order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Norgren publishes none for this line), flow capacity (the two datasheets state different flow figures), the B72G and B74G sizes, other Excelon products, and combinations built from several Excelon units.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
A 17 bar outlet range that is available only with the T-bar and the metal bowlOnly with care
Each dependency is a separate product rule; they can be written, but each one is easy to miss when the options are edited.		All the choices travel in one request, so every dependency is checked together.
A permitted temperature limit that depends on the bowl and on whether the gauge is fittedOnly with workarounds
The limit is a calculation over two choices, which a rules-based CPQ usually handles with custom code before it can compare it with the service temperature.		The limit is computed from the choices and compared with the service temperature on every call.
Accessories that must match the regulator (pipe adaptor by size and thread, gauge by thread, service kit by drain and element)Only with care
Each accessory needs its own lookup over the regulator options; a wrong part number looks fine in the quote.		The accessory is checked against the regulator in the same call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

  

  

    
What this validator catches: findings from its test cases

Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

    
1The B73G is for compressed air (the 01/26 sheet adds neutral gases); other media are for Norgren technical support, not an order.
2The international sheet says compressed air only and the 01/26 sheet says compressed air and neutral gases; a person should confirm the gas with Norgren.
3The lowest temperature 40 C is not below the highest temperature 20 C.
4The lowest ambient or media temperature -40 C is below the -34 C limit of the B73G.
5Below +2 C the air supply must be dry enough to avoid ice formation; a person should confirm the air quality for a lowest temperature of -40 C.
6The highest ambient or media temperature 55 C is above the 50 C limit for this bowl and gauge choice (transparent bowl 50 C, metal bowl 80 C, version with gauge 65 C).
7The highest ambient or media temperature 75 C is above the 65 C limit for this bowl and gauge choice (transparent bowl 50 C, metal bowl 80 C, version with gauge 65 C).
8The sheets give temperature and pressure limits for the transparent and metal bowls but not separately for the guarded bowl; a person should confirm this service with Norgren.
9The highest ambient or media temperature 90 C is above the 80 C limit for this bowl and gauge choice (transparent bowl 50 C, metal bowl 80 C, version with gauge 65 C).
10Below +2 C the air supply must be dry enough to avoid ice formation; a person should confirm the air quality for a lowest temperature of 0 C.
11The inlet pressure 12 bar is above the 10 bar maximum for this bowl (transparent bowl 10 bar, metal bowl 17 bar).
12The inlet pressure 18 bar is above the 17 bar maximum for this bowl (transparent bowl 10 bar, metal bowl 17 bar).
13The 0.7 to 17 bar outlet range is available only with T-bar adjustment.
14The 0.7 to 17 bar outlet range is available only with the metal bowl.
15A set pressure of 12 bar is outside the selected outlet pressure range of 0.3 to 10 bar; the sheet says not to use the unit outside its range.
16A set pressure of 0.2 bar is outside the selected outlet pressure range of 0.3 to 10 bar; the sheet says not to use the unit outside its range.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for an Excelon B73G filter/regulator for a compressed air line: port size and thread, adjustment, drain, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the public Norgren datasheets and returns a verdict, every reason and the temperature limit it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote an Excelon B73G filter/regulator, 3/8 inch, PTF thread, knob adjustment, manual drain, transparent bowl, 40 micron element, no fitted gauge, outlet range 0.3 to 10 bar, relieving diaphragm. The inlet pressure is 8 bar, the set pressure 6 bar, the minimum air flow 5 dm3/s, and the ambient temperature runs from 10 to 35 C on compressed air. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. The Quikmount pipe adaptor must match the port size and thread form of the regulator. The R1/8 gauges fit the ISO G version and the 1/4 NPT gauges fit the PTF version. The service kit must match the drain type (manual or auto) and the element (40 or 5 micron) of the regulator.
    6. 
      
  6. The validator returned three blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for accessories that must match the regulator (pipe adaptor by size and thread, gauge by thread, service kit by drain and element), a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the pipe adaptor to Quikmount pipe adaptor 4315-02 (3/8 ptf) and the gauge accessory to 1/4 npt gauge 0 to 160 psig (18-015-209).
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. The service kit must match the drain type (manual or auto) and the element (40 or 5 micron) of the regulator.
    12. 
      
  12. Two findings cleared; still blocked on service kit does not match drain and element.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the service kit to Service kit b73g-kitm40r (manual drain, 40 micron).
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is cleared.
    18. 
      
  18. Three problems caught in one call, fixed in two passes, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer.
    19.
