Cla-Val 302M Automatic Fueling / Defueling Valve

The Cla-Val 302M is an automatic control valve designed for fueling and defueling operations in naval aviation fuel systems, compatible with AV gas and jet fuel. Typical installation is on shipboard aircraft refueling stations for vessels such as CVN, LHA, LHD, LPD, and LPH. The valve is supplied in 2½” size with flanged ends per MIL-F-20042 Class 250.

Control Function

The 302M regulates pressure and mitigates surge during fueling. The same assembly supports defueling via an internal three-way configuration, enabling distinct flow paths for critical hot refueling operations.

Operation is integrated with the Cla-Val 345GF Semi Dry-Break Disconnect Assembly, which signals the pump and actuates the solenoid on the 302M to initiate fueling.

Materials and Construction

  • Body: valve bronze
  • Internal parts: Monel (refer to datasheet)
  • Connection: flanged
  • Specification: MIL-F-20042 Class 250
  • Size: 2½”
  • Media: AV gas, jet fuel

Material selection must be verified for fuel compatibility, additives, galvanic corrosion, and fuel system cleanliness requirements.

Selection Criteria

Prior to procurement, confirm the following:

  • Operating pressure and surge conditions
  • Fueling/defueling requirements per P&ID
  • Dry-break connection type
  • Compatibility with 345GF or existing disconnect assembly
  • Flanges per MIL-F-20042 Class 250
  • Naval or military specification requirements

Maintenance

Periodic inspection should address seat tightness, pilot control response, solenoid function, ejector strainer, flow control, and flange leakage. Pressure variation during filling should be recorded, as it may indicate pilot circuit contamination or control malfunction.

FAQ

Is this a manual fuel shutoff valve?
No. It is an automatic pressure and flow control valve for fueling/defueling.

Is it suitable for diesel fuel?
The 302M is specified for AV gas and jet fuel systems.

Does it accept electrical signals?
Yes, the datasheet specifies solenoid control in the actuation circuit.
