An AI sales agent's control valve order, checked before it goes out

An AI sales agent prepares an order for an Azbil single-seated control valve: the series, size, pressure rating, end connection, body and trim material, operating temperature, leakage class, required Cv, options and rangeability. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of Azbil's published Industrial Control Valves Selection Guide and returns a verdict and every reason. If anything is blocked, the order is not released.

Scope: Azbil AGVB/AGVM, HLS/HLC, HTS/HSC, HPS and micro-flow VSM valves: size, rating, ends, materials, temperature, leakage, Cv, options, rangeability. See everything this validator covers

This validator models orders for six Azbil single-seated valve series from the CA2-8000 selection guide, not just the scenarios shown below.

  • Series — AGVB, AGVM, HLS/HLC, HTS/HSC, HPS and the micro-flow VSM. The VST prefix is left out because the guide lists it twice with conflicting data.
  • Size, rating and ends — the size range of each series (the VSM only in fixed threaded and flanged sizes), the ANSI class or JIS K range for each series, and the end connections each series lists (flange facings, welded ends, threaded ends for the VSM).
  • Materials and leakage — body (the VSM is stainless steel only), trim materials by series, and the leakage classes each series lists.
  • Cv, temperature and rangeability — the Cv and temperature range of each series (the HPS Cv limit depends on the ANSI class), rangeability up to 50 to 1, 75 to 1 as an option that goes to a person, and 30 to 1 for the VSM.
  • Options and paperwork — bellows seal bonnet and steam jacket (HLS and HTS only), low emission packing (not HPS or VSM), SIL3 (not VSM), and the specification sheet cited on the order, which must be the one the guide lists for the series.

Any order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (the guide publishes none, so this validator produces no price build-up or line-item quote), sizing calculations, double-seated and other Azbil valve types, and actuator selection.

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
Limits that depend on the seriesOnly with care
Size, rating, temperature and Cv ranges differ for every series, and a rules-based CPQ needs a rule per series that must be kept in step with the guide.		Every range is looked up for the chosen series on every call.
A limit that depends on another fieldOnly with workarounds
The HPS Cv limit falls from 110 to 75 at ANSI class 2500, which is a cross-field rule.		The class and the Cv are compared together, and a JIS rating the guide does not map goes to a person.
Options available on only some seriesOnly with care
Bellows bonnet, steam jacket, low emission packing and SIL3 each apply to a different set of series.		The options and the series are checked together.
The specification sheet cited on the orderOnly with workarounds
Checking that the sheet number matches the series is a cross-line text rule that is easy to skip.		The cited sheet is compared with the one the guide lists for the series.
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.

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 Azbil single-seated control valve: the series, size, pressure rating, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of Azbil's published Industrial Control Valves Selection Guide and returns a verdict and every reason. If anything is blocked, the order is not released.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote an Azbil AGVB valve, 1 inch, ANSI class 300, raised-face flange, carbon steel body with 329J1SS trim, for -200 degrees C. The order cites specification sheet SS2_AGV200_0001. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with four findings, all in one answer. The pressure rating 300 is outside the 150 that the selected series offers for that standard. The trim material is not offered on the selected valve series. The operating temperature of -200 degrees C is outside the selected series range of -196 to 400 degrees C. The other one is on screen.
    6. 
      
  6. The validator returned four 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 limits that depend on the series, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the series to AGVM, the trim material to 316SS and the operating temperature to -196 degrees C.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. The leakage class is not offered on the selected valve series.
    12. 
      
  12. Three findings cleared. Still blocking: leakage class not offered.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the leakage class to VI.
    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. Four 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. Now you can try the other scenarios yourself.
    19.
