Module 3: Obsolescence & Supply Chain Deep Dive

A failed Woodward 5852-1062 can interrupt fuel-gas admission on a large-bore gas or dual-fuel engine because the component is associated with the SOGAV 250 gas admission architecture. Current technical and inventory records identify 5852-1062 with the 1200 N solenoid and the SOGAV 250 application. A SOGAV valve is installed per cylinder and controls gas admission into the engine’s intake path; Woodward describes the SOGAV family as electrically actuated, high-response gas admission valves for four-cycle, turbocharged natural-gas and dual-fuel engines.

For an operating engine, sourcing the exact solenoid assembly can be substantially less expensive than replacing an entire gas-admission valve or redesigning the fuel-control architecture. Existing manifolds, valve bodies, electrical harnesses and engine-control integration can remain intact when the correct component is used. The lifecycle consideration is important, however: Woodward now states that the SOGAV 250 is being succeeded by the SOGAV 235 for new marine applications, which makes legacy 5852-1062 inventory strategically relevant to installed equipment. Secondary technical records associate 5852-1062 with a maximum coil resistance of 1.91 Ω at rated temperature, giving maintenance teams a useful electrical screening value before a replacement is installed.

Module 4: Compatibility & Replacement Matrix

Woodward’s current SOGAV information describes the valve as one component of a complete gaseous-fuel admission system and states that one valve is required for each cylinder.

Field Traps — Watch Out

Wrong solenoid configuration: Do not treat every SOGAV solenoid as interchangeable. The 5852-1062 / 1200 N identification should be matched against the installed valve and engine documentation. Secondary records explicitly associate 5852-1062 with the SOGAV 250 / 1200 N configuration.

Gas-system sealing: Woodward’s SOGAV installation instructions require the gas manifold to be clean and call for leak checking after installation. The solenoid or valve should therefore not be released to service until the complete gas path has passed the applicable leak and functional tests.

Module 5: Quality Assurance & Testing SOP

For a gas-admission solenoid, electrical continuity alone does not establish service readiness. Testing should cover coil condition, mechanical operation and the complete valve interface.

1. Part identity verification: Record Woodward 5852-1062, serial/lot data, valve assembly reference and all visible markings.
2. OEM anti-counterfeit visual inspection: Inspect nameplates, coil housing, electrical connector, fasteners, machining and evidence of unauthorized repair.
3. Mechanical inspection: Check the solenoid body, plunger interface, mounting hardware, seals and mating valve components.
4. Coil resistance test: Measure coil resistance at controlled ambient conditions and compare the result with the applicable SOGAV specification; the available documentation gives 1.91 Ω maximum at rated temperature for 5852-1062.
5. Insulation test: Perform the applicable winding-to-ground insulation check using the valve manufacturer’s permitted test method.
6. Connector continuity test: Verify electrical continuity through the connector and harness interface.
7. Power-on actuation test: Apply the approved coil voltage using a controlled test source and verify positive solenoid actuation.
8. Force/response test: Where test equipment permits, verify the expected 1200 N solenoid capability and repeatable actuation response.
9. Valve functional test: Install or couple the solenoid to a compatible SOGAV test assembly and verify opening/closing behavior.
10. Gas-path leak test: Pressurize the applicable test section with the approved test medium and inspect all interfaces for leakage. Woodward specifically calls for leak checks after SOGAV installation.
11. Repeated-cycle test: Exercise the solenoid through multiple controlled cycles and monitor resistance, response time and thermal behavior.
12. Final QC release: Record coil resistance, test voltage, actuation results, leak-test results, serial traceability and photographs before protected shipment.

Woodward notes that SOGAV installation work involves fuel-gas handling and hazardous-location considerations, and its manual emphasizes following plant safety procedures before service.

Module 6: Procurement & Lifecycle FAQ

1. Is Woodward 5852-1062 genuinely in stock, and what is the emergency-shipping cutoff?

Current secondary inventory records show 5852-1062 offered as new and used stock, including listings identifying it as a SOGAV 250 / 1200 N solenoid. Availability varies by inventory holder, so physical confirmation is required before a PO is released. For emergency procurement, request actual-unit photographs, complete nameplate data, quantity, condition, test status and same-day carrier cutoff.

2. How do you verify the condition and authenticity of a surplus 5852-1062?

Require complete Woodward part-number verification, serial traceability, coil inspection, resistance measurement, insulation testing, controlled actuation and valve-interface testing. For a gas admission application, add a documented leak test before approving the unit for installation.

3. Are firmware compatibility issues relevant before issuing the PO?

Firmware is not normally the primary issue for the 5852-1062 solenoid itself. The important compatibility checks are coil voltage, connector arrangement, solenoid force, mating SOGAV valve configuration and the engine controller’s output circuit. The 5852-1062 should not be substituted based only on physical resemblance.

4. Is 5852-1062 the complete SOGAV 250 valve?

No. Available records identify 5852-1062 as the 1200 N solenoid associated with the SOGAV 250, while Woodward describes SOGAV as a complete gas-admission valve family. A solenoid replacement should therefore be matched to the specific valve assembly and engine installation rather than assumed to be an entire valve.

5. What warranty and return terms should procurement require?

The PO should specify Woodward 5852-1062, the associated SOGAV 250 / 1200 N configuration, accepted condition, coil-test requirements, functional-test scope, warranty duration, DOA definition and return window. For critical gas-engine service, require documented electrical and mechanical testing before shipment.
