Predictika · Grooved piping coupling selection

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

An AI sales agent prepares an order for Style 77 Standard Flexible Couplings: the size, the working pressure, the gasket grade, the service and temperature, the bolts, and the ratings it quotes to the customer. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published coupling data and returns a verdict, every reason and the figures it computed.

Scope: Victaulic Style 77 Standard Flexible Couplings (pressure rating by size band, Grade E and Grade T gaskets, service and temperature, bolts and coating). See everything this validator covers

This validator models Style 77 coupling selection as published in Victaulic publication 06.04, not just the scenarios shown below.

  • Size and pressure — the published maximum working pressure for 3/4 to 6 inch (1000 psi), 8 to 12 inch (800 psi) and 14 to 20 inch (300 psi) sizes; an order above the rating, or stating a different rating, is blocked.
  • Gasket grade, service and temperature — Grade E (EPDM) covers −30 to 230 °F and is not compatible with petroleum or steam; Grade T (nitrile) covers −20 to 180 °F, suits petroleum products, oils and air with oil vapors, and is not suitable for hot water above 150 °F. A service the publication does not list for the chosen grade goes to a person for approval.
  • Bolts and coating — carbon steel bolts are standard and stainless steel bolts are offered in imperial sizes only; the housing coating is orange enamel as standard or galvanized as an option.

Any Style 77 order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Victaulic publishes no list prices for couplings, so this validator produces no price build-up or line-item quote), 22 and 24 inch sizes, other coupling styles, other gasket grades, hot dry air limits, and end-play and deflection data. Approval for unlisted services is this model's reading of the publication, which refers to a separate gasket selection guide.

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 pressure rating that depends on the size bandOnly with care
A lookup from size to rating and a comparison with the order; it works, but each new size band is another rule to keep in step.		The size band and the working pressure are in one request and every comparison runs together.
Gaskets that suit some services and temperatures but not othersOnly with workarounds
Each grade has its own temperature range, excluded services and a hot-water limit, so the rules multiply with every grade and service.		Gasket, service and temperature are checked together with every other rule.
Ratings stated on the order that must match the published onesOnly with workarounds
The expected rating depends on the size band or gasket, so each stated figure needs its own lookup and comparison.		The expected figures are computed on every call and compared with what the order states.
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.

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 Style 77 Standard Flexible Couplings: the size, the working pressure, the gasket grade, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published coupling data 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 Style 77 Standard Flexible Couplings in the 14 to 20 inch size band for petroleum service at 120°F and 400 psi working pressure. The order states a pressure rating of 1000 psi and a gasket maximum of 230°F. 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 working pressure is 400 psi; Style 77 in this size band is rated for 300 psi maximum. The Grade E (EPDM) gasket is not compatible with petroleum services. Stainless steel bolts are offered in imperial sizes only; the order is for metric sizes. 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 a pressure rating that depends on the size band, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the working pressure to 300 psi, the gasket to Grade T (nitrile), the pipe sizes to imperial, the stated pressure rating to 300 psi and the stated gasket maximum to 180.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All four earlier findings are cleared.
    13. 
      
  13. Four problems caught in one call, fixed in one pass, 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.
