Predictika · Industrial valves
An AI sales agent prepares a quote for high-pressure solenoid valves: a hydrogen valve for a refueling station, a natural-gas valve block for a CNG dispenser or a valve for an electrolyzer, with its coil, voltage, pressure and temperature conditions. Before the quote goes out, the agent sends it to Predictika, which checks it against a declarative model of Seitz's public product pages and factsheets and returns a verdict, every reason and the total it computed.
This validator models a quote for high-pressure solenoid valves from the Seitz product lines below, based on the public Seitz product pages and factsheets. It handles any quote for these products, not just the scenarios shown. Where a rule is a published Seitz figure it says so; limits and prices that are only typical are labelled that way.
Any quote for these products that touches these rules is in scope — not only the scenarios pictured here. Not covered: HyValve Mosaic, nuclear power plant valves, engine systems valves, PET stretch-blow valves and blocks, other coil types, dimensions, certification paperwork, freight and installation. The customers are fictional.

What this means
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 caught | Typical rules-based CPQ | Predictika |
|---|---|---|
| Coils and voltages that depend on the valve family | Only with workarounds HyValve and HySync take the 2F86 coil, ProValve takes the 14 A 80, 14 C 80 or 14 F 52, and each coil offers its own voltages (HySync only 24 V AC/DC). That is a chain of three dependent lists, not one pick list. | Valve, coil and voltage are checked together on every call. |
| Housing material that depends on the variant and the voltage | Only with workarounds Each HyValve variant lists its own 1.4404 or 1.4435 housings, and the 3108 A at 230 V exists only in 1.4404. The limit sits on a different field than the one being chosen. | Material is checked against the variant and the voltage chosen. |
| Pressure, flow and temperature limits that differ by valve and coil | Only with workarounds A pressure range per valve, a flow capacity per type and an ambient range that changes with the coil are three tables across different fields. Most quote setups carry none of them. | Pressure, required flow, ambient and medium temperature are compared with the limits for the chosen valve and coil. |
| Medium that fits one family and not another | Only with care Hydrogen, saturated wet hydrogen and natural gas each have their own valves. Nothing stops a natural-gas valve from being quoted on a hydrogen line unless a rule exists. | The medium is compared with the valve family. |
| Port connections that only some valves take | Only with care ProValve needs a G, SAE UNF or ANPT port; the HyValve and HySync variants have fixed tube connections and take none. | Port choice is checked against the family. |
| ServiceKits that exist for some valves only | Only with care The filter kit belongs to the 3055 block with filters; the small and big kits belong to ProValve. A kit can be added to any quote line unless a rule says otherwise. | Kit and valve are checked together. |
| Guidance that needs a person, such as a pressure within 5 percent of the maximum | Only with workarounds These are engineering judgment calls, not hard rules. Quote tools tend to either ignore them or block the quote outright. | The quote is not blocked; it goes to a person with the reason listed. |
| A stated total that has to agree with the valves and coils | Only with workarounds Blocks carry three or six coils, kits multiply per valve, and the total typed on the quote can drift from them without anyone noticing. | The total is computed from the choices and compared with the total the quote states. |
| Every problem returned in one answer | Only 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. |
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.
| 1 | The medium does not match the selected valve; HyValve valves are rated for hydrogen, HySync for hydrogen and saturated wet hydrogen, and ProValve valves for natural gas. |
| 2 | The solenoid coil does not fit the selected valve; HyValve and HySync use the 2F86 coil, and ProValve valves and blocks use the 14 A 80, 14 C 80 or 14 F 52 coil. |
| 3 | That rated voltage is not available with the selected coil; the 2F86 comes in 24 V AC/DC and 230 V AC (HySync 24 V AC/DC only), the 14 A 80 in 24 V DC, the 14 C 80 in 24 V AC, 110 V AC and 230 V AC, and the 14 F 52 in 24 V AC/DC and 230 V AC/DC. |
| 4 | That housing material is not offered for the selected valve and voltage; each HyValve variant is listed in 1.4404 or 1.4435 stainless steel as its factsheet shows (the 3108 A at 230 V in 1.4404 only), while HySync and ProValve have a single stainless steel housing. |
| 5 | ProValve valves and blocks need a port connection (G thread, SAE UNF or ANPT), while the HyValve and HySync variants have a fixed tube connection and take none. |
| 6 | An operating pressure of 700 bar is outside the 10 to 550 bar range of the selected valve. |
| 7 | An operating pressure of 550 bar is within 5 percent of the 550 bar maximum of the selected valve; an application engineer confirms the duty. |
| 8 | An installation ambient range of -21 to 40 °C is outside the -20 to 50 °C that the selected valve and coil cover. |
| 9 | A medium temperature of -41 °C is outside the -40 to 85 °C range of the selected valve. |
| 10 | The required flow of Kv 0.5 m³/h is above the Kv 0.009 m³/h that the selected valve provides. |
| 11 | The required flow of Kv 0.6 m³/h uses more than 90 percent of the Kv 0.663 m³/h that the selected valve provides; an application engineer confirms it. |
| 12 | That service kit is not offered for the selected valve; this quote lists the small and big ServiceKits for ProValve only, and the filter ServiceKit only for the ProValve Multi 3055 block with filters (3055/6F). |
| 13 | The quote has 0 valves; at least one is needed. |
| 14 | Orders of 25 valves or more are confirmed by a sales manager before they are sent; this one has 25. |
| 15 | A discount of $6,008 on a list price of $62,600 is more than 8 percent and needs a manager to approve it. |
| 16 | A discount of $10,390 on a list price of $62,600 is more than the 15 percent limit. |
| 17 | The quote states a total of $23,200, but the valves, coils, kits and discount give $25,040. |
