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

An AI sales agent prepares an order for Neles RotaryGlobe Series ZX control valves: the pressure class and size, the trim, the pneumatic actuator, the valve controller and its control signal, and the process and site the valves will serve. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the figures the public Valmet bulletin publishes and returns a verdict, every reason and the figures it computed.

Scope: Neles RotaryGlobe Series ZX control valves with B1C and QPX actuators and the ND9000, NDX, NE700 and NP700 valve controllers. See everything this validator covers

This validator models an order for the Neles RotaryGlobe Series ZX control valve, based on the public Valmet bulletin 1RG20EN (4/2022), not just the scenarios shown below.

  • Class and size — pressure classes ASME 150 to 1500 and PN 40 to 100 against the sizes the bulletin offers (class 900 only in the 3 and 4 inch sizes), with the face-to-face length of each class and size.
  • Trim — the 30 trim types against the valve sizes that offer them, with the Cv and initial opening the bulletin lists, and the process temperature limits.
  • Actuator — the 12 B1C and QPX pneumatic actuators against the size and pressure class they are listed for, the shut-off pressure the valve must hold, the minimum air supply and the ambient temperature range.
  • Valve controller — the ND9000, NDX, NE700 and NP700 controllers against the control signals and communication protocols each is listed for, and their ambient temperature range; an order with no actuator, or a PN 63 body with an actuator, goes to a person.

Any Neles RotaryGlobe ZX order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (the bulletin publishes none, so this page shows no price build-up), other Neles valve families, and Valmet's own order entry rules.

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
Class 900 only in the 3 and 4 inch sizesOnly with care
The class and size are on separate option lines, so each unavailable pair needs its own rule, and a catalog update means editing them.		Class and size arrive in one request and are matched to the bulletin on every call.
Trim against the valve sizeOnly with workarounds
Each trim is offered in only some sizes, each with its own Cv and opening, so it needs a table per trim.		Trim, size and the stated Cv are compared together.
Actuator against size, class and the shut-off pressureOnly with workarounds
The shut-off limit depends on actuator, size, class and spring action together, so it is often left to engineering review.		Actuator, size, class and the required pressure are checked in the same call.
Controller, control signal and air supplyOnly with care
The signal belongs to the controller and the air supply to the actuator, on different lines, so a mismatch is rarely caught at order entry.		Controller, signal and supply travel with the order and are checked together.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so a person 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 order has no actuator; a person should confirm the customer will supply and mount one.
2The bulletin actuator table lists ASME classes only; a person should confirm the actuator shut-off pressure for this PN-rated body.
3The order has 0 valves; at least 1 is needed.
4ASME class 900 is available only in the 3 and 4 inch sizes; the bulletin does not list it in the 1/2 and 3/4 inch sizes.

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 Neles RotaryGlobe Series ZX control valves: the pressure class and size, the trim, the pneumatic actuator, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the figures the public Valmet bulletin publishes 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 quote 8 Neles RotaryGlobe ZX control valves, 3 inch, class 600, with an L700 trim and a B1C13 actuator with spring to close. The valves must shut off against 60 bar at a process temperature of 200 degrees Celsius, on an air supply of 3.8 barG. 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 selected trim type is not listed for this valve size in the bulletin trim tables. The air supply is 3.8 barG; the bulletin lists a minimum of 4.0 barG for this actuator. The control signal on the order is not one of the inputs or communication protocols the bulletin lists for the selected valve controller.
    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 controller, control signal and air supply, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the trim to L350, the control signal to pneumatic and the stated Trim Cv as to 35.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. The air supply is 3.8 barG; the bulletin lists a minimum of 4.0 barG for this actuator.
    12. 
      
  12. Two findings cleared; still blocked on air supply below the actuator minimum.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the air supply to 5 barG.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is cleared, and the validator's figure matches the quote.
    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.
