The OEM catalog lists this number as a combination valve for natural gas. According to FORM F-37136 Rev. A (January 2024) the line reads “00-410841-00022 Combination Valve (Nat. Gas)”, with the LP equivalent on the next line as a separate number.

Pilot safety and main-burner gas regulation on the mainstream Vulcan gas fryer lines (EF3/EF4/EF5, GR/GRC/GRD/GRMF, 1GR, 2GR–4GR) and on Hobart 1HG-M series fryers. This is the highest-fitment gas valve in the ITW fryer range — distributor catalogs list it against dozens of models.
A combination valve: a safety magnet held by the pilot's thermopile, a diaphragm operator that the thermostat opens, a pressure regulator and a gas cock in one body. This is a millivolt valve — the thermostat switches millivolts, not mains voltage. Most 'bad valve' diagnoses are really a missing call, a weak thermopile or a dirty inlet screen.
| Symptom | This part? | Check first |
|---|---|---|
| Ignition sequence runs, main burner never lights | Possible — operator not pulling in | Call signal at the operator terminals, then inlet pressure |
| Burner lights and then drops out | Possible — safety circuit losing hold | Thermopile output under load, terminal condition, pilot flame quality |
| Burner stays on after the call ends | Yes — operator stuck open (safety) | Stop using the fryer; verify with the call removed before replacing anything |
| Valve chatters or buzzes | Possible — low operating signal | Supply voltage / millivolts, loose spade terminals, corroded ground |
Yes — 00-410841-00022 is the ITW/Vulcan number for the Robertshaw 7000BMVR, catalog number 700-504.
No. VF1, VMF1, VF90, VFD90 and related VF/VMF models are electric fryers and have no gas valve. Use the EF / GR / 1GR / 1HG lines for gas fitment.
-00022 is the natural-gas build; -00023 is the same valve in propane build. Both share the 51-1470 conversion kit.

Capillary, millivolt and high-limit thermostats in these part families are produced in volume in China. Public supplier directories list manufacturers concentrated in specific industrial clusters: Zhongshan (Guangdong) for capillary, millivolt and deep-fryer thermostats; Wenzhou (Zhejiang) for capillary, gas, immersion and mechanical thermostats with OEM/ODM capability; and Jinan (Shandong) for gas-valve and thermostatic gas-control components. When sourcing these parts from China, verify: dimensional drawings, sensing-bulb and capillary specifications, temperature accuracy, electrical ratings, cycle-life testing and applicable safety certifications (CE / CQC / UL). A high-limit safety thermostat must not be substituted on the basis of physical fit alone.
