An AI sales agent's Mark 100 control valve quote, checked before it goes out

An AI sales agent prepares a quote for Flowserve Mark 100 control valves: the valve size and pressure class, the trim and its flow direction, the flow capacity the customer needs, the seal and the process temperature, the shutoff class, the actuator, and the face-to-face dimension the quote states. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the tables in the Flowserve Mark 100 technical bulletin and returns a verdict, every reason and the figures it computed.

Scope: Mark 100 control valves (sizes 6 to 16 inch, with larger sizes sent to a person): trim, flow capacity, seal temperature and shutoff, actuator and face-to-face dimension from the technical bulletin. See everything this validator covers

This validator models a quote for one Mark 100 valve configuration at a time, based on the tables in the public Flowserve Mark 100 technical bulletin (VATB003320-00, March 2026), not just the scenarios shown below.

  • Size, class and trim — valve sizes 6 to 16 inch in classes 150, 300 and 600, the three standard trim sizes listed for each valve size with their stroke, and the flanged face-to-face dimension for each size and class. A stated face-to-face dimension must equal the bulletin's.
  • Flow capacity — the capacity the customer needs against the capacity the bulletin lists for the chosen size, trim and flow direction (under or over the plug), for equal percent and linear trim. Quick open and the severe service trims (MegaStream, cavity control, channel stream and Diamondback) have no listed capacity in the bulletin and go to a person for approval. The bulletin does not state the unit of its capacity table, so the validator compares the numbers as they are given.
  • Seals and shutoff — the temperature range of each seal (Buna, Viton, EPDM, filled PTFE, spring energized and metal multi) against the process temperature, and the ANSI shutoff class each seal is listed for. Class VI is listed only with the optional soft seat, and the metal multi seal with a severe service trim is limited to Class III.
  • Actuators — the aluminum, carbon steel VLC and carbon steel VL-ES actuator sizes the bulletin offers with each valve size, and the rule that carbon steel sizes 300 and 400 are available only in the VL-ES series.

Any Mark 100 quote that touches these rules is in scope — not only the scenarios pictured here. Valves of 18 inch and larger are sent to a person for approval, because the bulletin's specification table lists sizes 6 to 16 while later tables go up to 30. Not covered: prices (Flowserve does not publish them), weights, carbon seals (the bulletin's temperature limit for them is unreadable in the PDF), Kalrez seals, capacity figures for 18 inch and larger valves, the face-to-face dimension of buttweld ends (not in the bulletin), other Flowserve valve families, positioners and accessories.

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
Trim sizes and strokes that exist only for certain valve sizesOnly with workarounds
Each valve size has its own three trim sizes, strokes and capacities. A rules-based CPQ needs a compatibility table or one rule per row, and every bulletin revision means editing them.		The size and trim arrive in one request and are matched to the published row on every call.
Capacity that depends on size, trim and flow directionOnly with care
The capacity to compare with is a lookup on three choices, and quick open and severe service trims have none, so a rule must handle the gap.		The listed capacity is looked up on every call, and a trim with no listed capacity is sent to a person.
Seal temperature range and shutoff class togetherOnly with care
Each seal has its own temperature range and shutoff class, and one seal changes class with the trim. These are product rules that must be kept in step.		Seal, temperature, trim and shutoff class are in one request and checked together.
Face-to-face dimension the quote statesOnly with care
The stated figure comes from the size and class, so a rule has to look it up and compare.		The stated dimension is a field in the request, compared with the bulletin's on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the quote 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 quote has 0 valves; at least 1 is needed.
2A valve size of 9 inches is not listed; the bulletin gives the Mark 100 in 6, 8, 10, 12, 14, 16, 18, 20, 24 and 30 inch.
3ANSI class 900 is not offered; the bulletin lists classes 150, 300 and 600.
4A trim size of 800 (hundredths of an inch) is not listed for the 6-inch Mark 100 valve in the standard trim table.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a quote for Flowserve Mark 100 control valves: the valve size and pressure class, the trim and its flow direction, the flow capacity the customer needs, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the tables in the Flowserve Mark 100 technical bulletin 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 Mark 100 control valves of 8 inch, class 600, with equal percent trim of 7.75 inches, flowing under the plug. The customer needs a flow capacity of 700. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with two findings, all in one answer. The selected seal is listed with ANSI Class IV shutoff; the quote asks for Class V. An actuator of size 300 is not offered with the 8-inch valve in the actuator table.
    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 seal temperature range and shutoff class together, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the seal to viton and the actuator size to 100.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. The process temperature of -45 degrees Fahrenheit is outside the -15 to 400 degrees Fahrenheit range listed for the selected pressure balanced seal.
    12. 
      
  12. Two findings cleared, but the change brings a different blocking finding: process temperature outside the seal range.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the seal to EPDM.
    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.
    19.
