Predictika · Industrial check valve orders

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

An AI sales agent prepares an order for a pipeline or process engineer who needs a Goodwin check valve: dual plate or axial non-slam, the size, the fluid, the face-to-face length, the pressure rating and the body material. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of Goodwin's published product ranges and returns a verdict, every reason and the figures it computed.

Scope: Goodwin International dual plate and axial non-slam check valves: size ranges, valve type by size and fluid, face-to-face length, pressure rating and body material. See everything this validator covers

This validator models orders for two Goodwin International product lines, dual plate check valves and axial non-slam check valves (Types Z, N and NZ), against the ranges in Goodwin's public brochures for those lines (read October 6, 2026), not just the scenarios shown below.

  • Dual plate check valves — sizes 2 to 144 inches, six body styles (wafer, flanged, solid lug, buttweld end, buttweld end with access, hub-ended), ASME classes 150 to 2500, API ratings 2000 to 20000 and PN 10 to PN 400.
  • Axial check valves — Type Z solid disc for sizes 1 to 10 inches (liquids and gases), Type N radially guided ring disc for sizes 12 to 88 inches (liquids) and Type NZ centrally guided ring disc for sizes 12 to 88 inches (gases); ASME classes 150 to 2500, API ratings 2000 to 10000 and PN 10 to PN 400.
  • Face-to-face length — long, API 6D or compact for the axial valves; the compact length (Types NK and NC) is offered only for the ring disc valves.
  • Body material — the families Goodwin lists: irons, carbon steels, stainless steels, duplex and super duplex stainless steels, aluminum bronze, high nickel alloys and titanium.

Any Goodwin dual plate or axial check valve order that touches these ranges is in scope — not only the scenarios pictured here. Not covered: prices (Goodwin publishes none, so there is no price build-up or line-item quote), which size is offered in which pressure class or material (the brochures give ranges, not a size-by-class table), the end-connection options of axial valves, temperature limits, certifications and Goodwin's other products such as control valves. Goodwin valves are engineered to order, so a check against these ranges is a first filter, not a final quotation.

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 product range that changes with the valve typeOnly with care
Each type covers its own size band and its own fluid, so every combination of type, size and fluid needs its own rule, kept in step with the brochure.		The size band and the fluid are checked against the valve type chosen, together with everything else, in one pass.
A size that falls between two valve typesOnly with workarounds
Type Z stops at 10 inches and Types N and NZ start at 12, so an 11 inch order matches neither; catching that gap takes a rule written for it.		The gap is found because the size band of every type is checked, so an 11 inch request is reported with the reason.
A pressure rating whose limit depends on the productOnly with workarounds
The highest API rating is 20000 for dual plate but 10000 for axial valves, and ASME classes are a fixed list; each needs a conditional rule per product and per standard.		The rating is checked in the standard chosen and against the limit for the product line.
A fluid restriction tied to the valve typeOnly with care
Type N is for liquids and Type NZ is for gases; the restriction has to be written for each type and kept current.		The fluid is checked against the type 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.

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 a pipeline or process engineer who needs a Goodwin check valve: dual plate or axial non-slam, the size, the fluid, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of Goodwin's published product ranges 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 a 24 inch Goodwin axial check valve, Type N ring disc, with long face-to-face length, for a gas line, ASME class 3000, in stainless steel. It is ready to send.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with two findings, all in one answer. The Type N radially guided ring disc valve is for liquids; the fluid is a gas. ASME class 3000 is not one of the standard classes 150, 300, 600, 900, 1500 and 2500 (Goodwin offers ASME 150 to 2500).
    6. 
      
  6. The validator returned two 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 a product range that changes with the valve type, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the valve type to Type NZ ring disc.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. ASME class 3000 is not one of the standard classes 150, 300, 600, 900, 1500 and 2500 (Goodwin offers ASME 150 to 2500).
    12. 
      
  12. One finding cleared. Still blocking: not an ASME class.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the pressure rating to ASME class 2500.
    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. Two 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.
