An AI sales agent's spring-applied brake order, checked before it goes out

An AI sales agent prepares an order for the Kendrion INTORQ BFK458 spring-applied brake for a fictional hoist maker: the size, the design (adjustable, fixed or long-life), the coil voltage, the braking torque, the linings and the options. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published product rules and returns a verdict and every reason.

Scope: INTORQ BFK458 spring-applied brake orders: size, design, coil voltage, braking torque, linings, double brake, Cold Climate Version, safety-brake use, rear bores and monitoring microswitch. See everything this validator covers

This validator models single-brake and double-brake orders for the INTORQ BFK458 as described in Kendrion's public product page and operating instructions (read October 5, 2026), not just the scenarios shown below.

  • Sizes and voltages — sizes 06, 08, 10, 12, 14, 16, 18, 20 and 25, and the rated coil voltages 24, 96, 103, 170, 180, 190 and 205 V DC.
  • Designs — adjustable (E), fixed (N) and long-life (L); the long-life design is configured for sizes 06 to 12 only, has no rear bores or extensions, and has no microswitch in size 12.
  • Torque and linings — a braking torque from 1.5 to 600 Nm for the standard version; a double spring-applied brake cannot use HFC linings.
  • Options and use — air gap and wear monitoring is offered from size 12 upwards; the Cold Climate Version cannot be used as a safety brake; a microswitch on a safety brake is not covered by the safety certificate and goes to a person.

Any BFK458 order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (none are published), the exact torque each size offers, hub bore and flange details, ATEX and other certification details, rectifiers, shaft sealing rings and other accessories, and other INTORQ brake families.

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 design that only exists for some sizesOnly with care
The long-life design is limited to sizes 06 to 12, so it needs a rule tied to the size that has to be kept in step with the catalog.		The design and the size are in one request and checked on every call.
Options that exclude each otherOnly with workarounds
A rear bore, a microswitch or HFC linings each rule out something else depending on the design, size or brake type, so the rules multiply.		Every combination is checked together, in whatever order the choices arrive.
A temperature variant that depends on how the brake is usedOnly with workarounds
Whether the Cold Climate Version is allowed depends on the application, not on the product, so it is often left to a manual check.		Choosing the Cold Climate Version for a safety brake is a blocking finding.
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
Click to expand
    
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.

    
1Size 7 is not a BFK458 size; the sizes are 06, 08, 10, 12, 14, 16, 18, 20 and 25.
2A coil voltage of 48 V DC is not one of the rated voltages 24, 96, 103, 170, 180, 190 and 205 V DC.
3A braking torque of 700 Nm is outside the 1.5 to 600 Nm range of the standard version.
4A braking torque of 1 Nm is outside the 1.5 to 600 Nm range of the standard version.
5The long-life design can be configured only for sizes 06 to 12; the order is for size 14.
6Rear bores and extensions are not possible on the long-life design.
7A microswitch is not configurable on the long-life design in size 12.
8Air gap and wear monitoring is offered from size 12 upwards; the order is for size 10.
9Air gap and wear monitoring is offered from size 12 upwards; the order is for size 8.
10A double spring-applied brake with HFC linings is not permitted.
11When the brake is used as a safety brake, the extended low-temperature range of the Cold Climate Version must not be reached.
12The microswitch option is not covered by the safety certificate; a person should confirm it for this safety brake order.

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 the Kendrion INTORQ BFK458 spring-applied brake for a fictional hoist maker: the size, the design (adjustable, fixed or long-life), the coil voltage, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published product rules and returns a verdict and every reason.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote a double INTORQ BFK458 brake of size 14 in the fixed (N) design. It will be used as a safety brake. 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. A coil voltage of 48 V DC is not one of the rated voltages 24, 96, 103, 170, 180, 190 and 205 V DC. A double spring-applied brake with HFC linings is not permitted. When the brake is used as a safety brake, the extended low-temperature range of the Cold Climate Version must not be reached.
    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 a temperature variant that depends on how the brake is used, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the coil voltage to 205 V DC and the linings to standard.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. When the brake is used as a safety brake, the extended low-temperature range of the Cold Climate Version must not be reached.
    12. 
      
  12. Two findings cleared. Still blocking: Cold Climate Version not allowed for a safety brake.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the Cold Climate Version to no.
    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. Now you can try the other scenarios yourself.
