An AI sales agent's Moog servovalve order, checked before it goes out

An AI sales agent prepares an order for Moog D633 and D634 direct drive servo valves: the valve size, rated flow, spool, Y-port, seal and fluid, for an application with a given pressure and flow. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the ordering code in Moog's published catalog and returns a verdict, every reason and the figures it computed.

Scope: Moog D633 and D634 direct drive servo valves: rated flow codes, spool, Y-port, seal and fluid, operating pressures and flow. See everything this validator covers

This validator models orders for these two valve series, not just the scenarios shown below.

  • Ordering-code combinations — which rated flows each size offers (D633: 5, 10, 20 and 40 l/min; D634: 60 and 100 l/min); that the 2x2-way spool needs the Y-port; and that NBR and FKM seals are each listed only for certain fluids.
  • Application fit — the pressure on ports P, A and B against the 350 bar maximum, the pressure at port T against the 50 bar limit when the Y-port is closed, the flow the application needs against the maximum valve flow (D633 75 l/min, D634 180 l/min), and the rated flow stated on the order against the flow code.
  • Approval — the explosion-proof version, which the catalog lists as available upon request, goes to a person to confirm.

Any D633 or D634 order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Moog publishes none for these valves, so no price build-up or line-item quote is produced), other Moog valve series, digital-interface versions, accessories and servo electronics. Assumption: the maximum valve flow figures and ordering-code tables were read from the catalog through a text summarizer, twice; spool position and signal codes are carried on the order but carry no rules here.

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
Option combinations that depend on other options, such as a 2x2-way spool only with the Y-portOnly with care
Each restriction links two or more choices on the order code, so every pairing has to be written and kept in step for each valve size.		All choices are in one request and every restriction is checked together on every call.
Two valve sizes with different rated flows and maximum flowsOnly with care
The same flow code means different valves on each size, so rules are duplicated per size and drift apart.		The size is one more choice and the limits follow from it.
Seal material that must suit the fluidEasy
A compatibility lookup between two choices; routine in a product-rules CPQ.		The same check, made together with all the others on every call.
A pressure at port T that depends on whether the Y-port is openOnly with care
A threshold on an application figure that is not part of the product configuration, tied to a configuration choice.		The application figures are fields in the request and are compared with the chosen options on every call.
A rated flow stated on the order that disagrees with the flow codeOnly with workarounds
The stated figure is not part of the configuration, so comparing it with the code takes extra formulas.		The stated figure is one more field in the request and is compared with the computed rated flow on every 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.

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.

    
1A rated flow of 60 l/min is not offered on this valve size (the D633 offers 5, 10, 20 and 40 l/min; the D634 offers 60 and 100 l/min).
2A rated flow of 40 l/min is not offered on this valve size (the D633 offers 5, 10, 20 and 40 l/min; the D634 offers 60 and 100 l/min).

4The application runs at 351 bar on ports P, A and B; the maximum operating pressure of this valve is 350 bar.
5The application has 51 bar at port T; with the Y-port closed by a screw plug the limit is 50 bar, so the Y-port must be open (with filter insert).
6The 2x2-way spool is available only with the Y-port; the order has the Y-port closed.
7The chosen seal material is not listed for the chosen fluid (NBR is listed for HLP, PAO, HFDU, HEES, HFA and HFC fluids; FKM for HLP, PAO, HFD, HFDU, HEES and HFA fluids).

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 Moog D633 and D634 direct drive servo valves: the valve size, rated flow, spool, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the ordering code in Moog's published catalog and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please prepare an order for 8 Moog D633 direct drive servo valves with a rated flow of 20 l/min, a 2x2-way spool, the Y-port closed, FKM seals and HFC fluid. The application runs at 250 bar on ports P, A and B with 80 bar at port T and needs up to 50 l/min. 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 application has 80 bar at port T; with the Y-port closed by a screw plug the limit is 50 bar, so the Y-port must be open (with filter insert). The 2x2-way spool is available only with the Y-port; the order has the Y-port closed. The chosen seal material is not listed for the chosen fluid (NBR is listed for HLP, PAO, HFDU, HEES, HFA and HFC fluids; FKM for HLP, PAO, HFD, HFDU, HEES and HFA fluids).
    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 option combinations that depend on other options, such as a 2x2-way spool only with the Y-port, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the y-port to open, with filter insert.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. The chosen seal material is not listed for the chosen fluid (NBR is listed for HLP, PAO, HFDU, HEES, HFA and HFC fluids; FKM for HLP, PAO, HFD, HFDU, HEES and HFA fluids).
    12. 
      
  12. Two findings cleared; still blocked on seal not suited to the fluid.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the seal material to NBR.
    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.
