An AI sales agent's Rotork IQ3 actuator order, checked before it goes out

An AI sales agent prepares an order for a Rotork IQ3 electric valve actuator: the model and output speed, the supply, the valve base and coupling, the valve torque, thrust and stem, the duty and ambient temperature, the network card and the control options. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the figures Rotork publishes in the IQ3 and IQT3 range catalogue and returns a verdict, every reason and the figures it computed.

Scope: IQ3 single-phase, three-phase and DC actuators: output speed and rated torque, valve base, coupling, stem and thrust, duty, temperature, network cards and control options, from the public range catalogue. See everything this validator covers

This validator models a Rotork IQ3 actuator order based on the public IQ3 and IQT3 range catalogue (PUB002-038-00), not just the scenarios shown below.

  • Model, speed and torque — the output speed must be one the catalogue lists for the model, the valve torque must not exceed the rated torque at that speed, and a rated torque the order states must equal the catalogue figure.
  • Valve base, coupling and stem — the valve base and coupling must be available for the actuator size, the stem must fit the coupling, the valve thrust must stay within the thrust base rating, a non-thrust coupling takes no thrust, and the valve travel must fall within the settable turns.
  • Duty and environment — starts per hour against the nominal and maximum ratings, and the lowest and highest ambient temperatures against the range for the actuator type, including the combined cold and hot extreme.
  • Networks and control options — the device count and loop length of a Pakscan Classic loop, the actuator count, spacing and existing P3 network of Pakscan Wireless, the Remote Hand Station distance, interrupter timer periods, remote control supply ranges, and the options that analogue control, position and torque outputs, negative switching, indication contacts and mains-off communication need.
  • Approvals — a supply voltage outside the standard list, a speed the catalogue does not recommend for a direct-mounted gate valve, maximum torque needed for much of the travel, starts above the nominal rating, and hazardous-area or SIL options on a single-phase or DC type go to a person.

Any IQ3 order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Rotork does not publish list prices in the catalogue, so this page shows no price build-up), the IQT, IQTM and other ranges, certification details of a given enclosure, and lead times.

The AI sales agentBuilds the order from the conversation and says it is ready.

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
Rated torque that depends on model and output speedOnly with workarounds
Each model has a different rated torque at each output speed, so a rules-based CPQ needs a table or a rule for every combination, edited whenever the catalogue changes.		Model, speed and rated torque are looked up and compared with the valve torque and any stated torque on every call.
Stem, thrust and coupling for the chosen valve baseOnly with care
Whether the stem fits depends on the coupling and the valve base together, and thrust only applies to thrust couplings, so the checks must be written against each combination.		Coupling, base, stem and thrust are compared together, in any order.
Cold and hot extremes togetherOnly with workarounds
The catalogue limits the low and high ambient temperatures jointly by actuator type, which rules tend to check one end at a time.		Both temperatures are checked against the range for the actuator type on every call.
Network and control limits that interact with optionsOnly with care
Device counts, loop lengths and supply ranges depend on the network card, and several control outputs need a specific option, so each limit is a separate rule that must be kept in step.		Every network limit and option dependency is checked 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 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
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.

    
1This actuator model is not offered at an output speed of 100 rpm (50 Hz basis).
2The valve needs 300 Nm; this actuator at 192 rpm is rated for at most 140 Nm.
3The quote states a rated torque of 450 Nm; the catalogue rating for this model at this speed is 400 Nm.
4The selected drive coupling is not available for this actuator size and valve base.
5A valve base of flange size F16 is not available for this actuator size.
6The valve stem is 55 mm; the selected coupling on this valve base accepts at most 51 mm.
7The valve stem is 40 mm; the selected coupling on this valve base accepts at most 38 mm.
8The valve produces 120 kN of thrust; the thrust base on this valve base is rated for 100 kN.
9The valve produces 60 kN of thrust but the selected B-type coupling is a non-thrust coupling; a thrust base (type A) is needed.
10A supply frequency of 55 Hz is not 50 or 60 Hz.
11The IQS35 is not available at 115 volts.
12A supply of 345 V at 50 Hz is not in the standard voltage list for this model and speed; the catalogue says additional voltages are available, so Rotork should confirm.
13A supply of 24 V at 50 Hz is not in the standard voltage list for this model and speed; the catalogue says additional voltages are available, so Rotork should confirm.
14The catalogue does not recommend an output speed of 144 rpm for a direct-mounted gate valve; a person should confirm.
15The valve needs 9000 output turns; limits can be set between 2.5 and 8,000 output turns.
16Maximum torque is needed for 30 percent of the valve travel; the catalogue says to refer to Rotork above 20 percent.
17The duty is 100 starts per hour; the nominal rating is 60 starts per hour, so a person should confirm.
18The duty is 700 starts per hour; on-off and inching duty is rated at a nominal 60 starts per hour and at a rate not exceeding 600; modulating duty uses the IQM type.
19The lowest ambient temperature is -55 degrees Celsius; this actuator type is available down to -50 degrees Celsius.
20Ambient temperatures from -45 degrees Celsius up to 45 degrees Celsius are outside every range offered; below minus 40 degrees Celsius the range stops at 40 degrees Celsius.

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 Rotork IQ3 electric valve actuator: the model and output speed, the supply, the valve base and coupling, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the figures Rotork publishes in the IQ3 and IQT3 range catalogue 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 one Rotork IQ20 actuator at 24 rpm output speed on a 400 V, 50 Hz supply, with a flange F14 valve base and a Type A coupling. The valve has a 40 mm rising stem, needs 150 Nm and 40 kN of thrust and travels 40 turns. 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 and one approval, all in one answer. Ambient temperatures from -45 degrees Celsius up to 45 degrees Celsius are outside every range offered; below minus 40 degrees Celsius the range stops at 40 degrees Celsius. A Pakscan Classic loop supports up to 240 field devices; the quote has 260. A Pakscan Classic loop runs up to 20 km without repeaters; the quote has 25 km.
    6. 
      
  6. The validator returned three blocking findings and one approval 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 cold and hot extremes together, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the highest ambient to 40 degrees Celsius, the devices on the loop to 240 and the loop length to 20 km.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Not blocked, but held for a person.
    12. 
      
  12. The three blocking findings are cleared; one approval remains for a person: starts per hour above the nominal rating.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the starts per hour to 50.
    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. Four 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.
    19.
