Predictika · Solenoid and process valve orders

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

An AI sales agent prepares an order for servo-assisted 2/2-way diaphragm valves with their body, seal, port, voltage and cable plugs. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the ordering chart and operating limits and returns a verdict, every reason and the figures it computed.

Scope: Type 6213 servo-assisted 2/2-way diaphragm valves, standard and HP00 variants: body, seal, port, orifice, voltage, operating limits and cable plugs. See everything this validator covers

This validator models orders for Type 6213 servo-assisted 2/2-way diaphragm valves (standard and HP00 variants), not just the scenarios shown below.

  • What can be ordered — brass or stainless steel body, NBR, FKM or EPDM seal, G-thread port and orifice (DN10 to DN40) combinations exactly as the data sheet ordering chart lists them for the standard and HP00 variants; HP00 only in DN13 and DN20, with FKM or EPDM seals, on 24 V DC, 24 V 50/60 Hz or 230 V 50/60 Hz.
  • Operating limits — medium temperature range for the seal and coil, 0 to 10 bar pressure, and the minimum differential pressure of 0.5 bar for the standard variant (the HP00 variant opens without it).
  • Special cases — the drinking water version (brass body, EPDM seal, DN10 to DN20, up to 60 °C); 110 V 50 Hz, 120 V 60 Hz and NPT or Rc ports need approval because they are not in the ordering chart; one cable plug per valve; the flow (Kv) the customer needs and the Kv the quote states are compared with the data sheet.

Any order for these valves that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (none are published, so there is no price build-up or line-item quote), Kick and Drop coil, explosion-proof (ATEX/IECEx), gunmetal and other body variants, other valve types and accessories such as timers.

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
Port and orifice combinations that exist for one body or variant onlyOnly with care
One product rule per combination: 12 for brass, 8 for stainless steel, 3 for HP00. It works, but every change to the chart means editing many rules.		The variant, body, port and orifice are in one request and are checked against the ordering chart together.
Temperature limits that depend on the seal and on the coil that goes with the sizeOnly with care
The upper limit of EPDM changes from 90 to 100 degrees C with the coil fitted at larger sizes, so the rule needs the size as well as the seal.		The limit is computed from seal, variant and size on every call and compared with the medium temperature.
A variant that needs a minimum differential pressure and one that does notOnly with workarounds
The differential pressure is an application figure, not a product option, so a product-rule engine has no natural place to hold it and compare it with the variant.		Application figures travel with the order and are checked against the variant chosen.
The drinking water version that exists for one body, seal and size rangeOnly with care
A flag that restricts three other choices and a temperature limit; each restriction is another rule to keep consistent.		The flag and the choices it depends on are checked together, whatever order they arrive in.
Flow the customer needs and the Kv the quote statesOnly with care
Both are free-entry numbers; comparing them with the data sheet value for the chosen port and orifice needs a lookup and a comparison someone has to write and keep up.		The needed flow and the stated Kv are compared with the data sheet value on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as 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.

    
1The data sheet ordering chart has no Type 6213 with this combination of variant, body, port connection and orifice.
2The medium temperature is 85 degrees C, above the 80 degrees C maximum for this seal and coil.
3The medium temperature is -5 degrees C, below the 0 degrees C minimum for this seal.
4The medium temperature is 95 degrees C, above the 90 degrees C maximum for this seal and coil.
5The pressure range of the valve is 0 to 10 bar; the application has 12 bar.
6The standard variant needs a differential pressure of at least 0.5 bar to open the full cross section; the application has 300 mbar. The HP00 variant opens without differential pressure.
7The HP00 variant is ordered with FKM or EPDM seals only; there is no NBR seal HP00 in the ordering chart.
8The HP00 variant operates on 24 V DC, 24 V 50/60 Hz or 230 V 50/60 Hz only.
9The drinking water version (UBA) in the ordering chart is the standard brass-body variant with EPDM seal and an orifice of DN10 to DN20.
10The drinking water version is for cold and hot water up to 60 degrees C; the medium is at 70 degrees C.
11The data sheet states that the cable plug must be ordered separately; the quote has 4 valves and only 3 cable plugs.
12The application needs a Kv of 9.0 m3/h but the selected port and orifice give 8.3 m3/h for water.
13The quote states a Kv of 11.0 m3/h; the data sheet lists 8.3 m3/h for this port and orifice.
14110 V 50 Hz and 120 V 60 Hz are operating voltages in the general data, but the ordering chart lists 24 V DC, 24 V 50 Hz and 230 V 50 Hz; the article must be confirmed with the manufacturer.
15NPT and Rc port connections are listed as variants on request, not in the ordering chart; the article must be confirmed with the manufacturer.
16The data sheet states that the cable plug must be ordered separately; the quote has 4 valves and only 2 cable plugs.
17The medium temperature is 90 degrees C, above the 80 degrees C maximum for this seal and coil.
18The standard variant needs a differential pressure of at least 0.5 bar to open the full cross section; the application has 200 mbar. The HP00 variant opens without differential pressure.
19The application needs a Kv of 30.0 m3/h but the selected port and orifice give 23.0 m3/h for water.
20The quote states a Kv of 30.0 m3/h; the data sheet lists 23.0 m3/h for this port and orifice.

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 servo-assisted 2/2-way diaphragm valves with their body, seal, port, voltage and cable plugs. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the ordering chart and operating limits 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 4 Burkert Type 6213 servo-assisted 2/2-way diaphragm valves, standard variant, stainless steel body, EPDM seal, G 1 1/4 port with a DN40 orifice. The application needs a Kv of 25 m3/h and the quote states a Kv of 30 m3/h. 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 data sheet ordering chart has no Type 6213 with this combination of variant, body, port connection and orifice. The data sheet states that the cable plug must be ordered separately; the quote has 4 valves and only 2 cable plugs. The application needs a Kv of 25.0 m3/h but the selected port and orifice give 23.0 m3/h for water. 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 port and orifice combinations that exist for one body or variant only, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the port connection to G 1 1/2 and the cable plugs to 4.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All four earlier findings are cleared, and the validator's figure matches the quote.
    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.
    14.
