Predictika · Reciprocating compressor valves

An AI sales agent's compressor valve quote, checked before it goes out

An AI sales agent prepares a quote for HOERBIGER reciprocating compressor valves: which valve type, the compressor speed, the pressures, the temperature range, the valve diameter and the capacity control the customer wants. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the technical data HOERBIGER publishes for each valve type and returns a verdict, every reason and the figures it computed.

Scope: HOERBIGER CE, CT, HDS, RN and HPV compressor valves: published limits for speed, pressure, pressure differential, temperature and diameter, capacity control options and hydrogen service. See everything this validator covers

This validator models a quote for one compressor valve type at a time, based on the technical data HOERBIGER publishes on its product pages and in its brochures and flyers for the CE, CT, HDS, RN and HPV valves, not just the scenarios shown below.

  • Operating limits — the most the published data allows for each valve type: compressor speed, maximum pressure, pressure differential, temperature range and valve diameter. CE: 1,200 rpm, 200 bar, 100 bar differential, -40 to 230 °C, 48 to 314 mm. CT: 1,800 rpm, 350 bar, 150 bar differential, up to 230 °C, 77 to 221 mm. HDS: 1,200 rpm, 300 bar, 100 bar differential, -160 to 300 °C, 92 to 254 mm. RN: 2,000 rpm, up to 415 bar, -40 to 300 °C, 19 to 214 mm. HPV: 1,800 rpm, 800 bar, 400 bar differential, -20 to 300 °C, 19 to 57 mm.
  • Capacity control — HydroCOM is published for the CE and CT valves, eHydroCOM for the CE valve, and only On/Off for the HDS and RN valves. A control that is not listed blocks the quote. HOERBIGER publishes no capacity control options for the HPV valve, so any control on an HPV quote goes to a person.
  • Needs approval — the HDS limits that depend on the valve plate material, the RN pressure rating (30 to 415 bar depending on valve diameter), hydrogen service on valve types where the published data does not list it (it is listed for CE and HPV), and capacity control on the HPV valve.

Any quote for these five valve types that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (HOERBIGER publishes no list prices, so there is no price build-up), the CP valve (its brochure gives no operating limits), other HOERBIGER valve families, valve materials, spare parts and services, and the compressor itself. The limits are the maxima in the published data; a real application can need a smaller envelope, which HOERBIGER confirms.

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
Operating limits that differ for each valve typeOnly with care
Five valve types each have their own speed, pressure, differential, temperature and diameter limits, so a rule per type and limit is needed and has to be kept in step with the published data.		The limits are looked up from the chosen valve type and every one is compared with the quote on every call.
Capacity control options that only some valve types offerOnly with care
HydroCOM and eHydroCOM exist for some valves only, so a compatibility table or a rule per pair is needed.		The requested control is checked against the options published for the valve type.
Limits that depend on something not yet knownOnly with workarounds
The HDS limits depend on the valve plate material and the RN pressure rating on its diameter. A rule that treats the published maximum as the limit would pass quotes that are not yet confirmed.		These cases go to a person for approval until the dependency is confirmed, and every other finding still comes back with them.
A fact the published data does not stateOnly with workarounds
Hydrogen service is listed for some valve types and not others; a missing fact must not be silently treated as yes or as no.		A fact that is not published becomes an approval finding rather than a pass or a block.
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.

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 HOERBIGER reciprocating compressor valves: which valve type, the compressor speed, the pressures, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the technical data HOERBIGER publishes for each valve type 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 CE profiled ring valve of 250 mm for a compressor running at 1,500 rpm, with a maximum pressure of 250 bar. It is ready to send. 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. The compressor speed is 1,500 rpm; the selected valve type is published for at most 1,200 rpm. The maximum pressure is 250 bar; the selected valve type is published for at most 200 bar. The pressure differential is 120 bar; the selected valve type is published for at most 100 bar.
    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 operating limits that differ for each 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 compressor speed to 1,100 rpm, the maximum pressure to 180 bar and the pressure differential to 90 bar.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All three earlier findings are cleared.
    13. 
      
  13. Three 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.
