Flanged Float Control - CFF18MT-H2 | Cla-Val

Cla-Val CFF18MT-H2 Flanged Float Level Control with Tester

The Cla-Val CFF18MT-H2 is a float-actuated level control valve designed for fuel-water filter separators in marine and aviation fuel handling systems. The CFF series is applied for level regulation in filter separators and aircraft fueling installations. The CFF18MT-H2 variant is specified as a Flanged Float Control for Filter Separators – with Tester in technical catalogs.

Functional Role

The float mechanism monitors the interface level within the separator vessel. The output signal can be integrated into automatic water drain systems or fuel shutoff logic, depending on process requirements and system configuration.

The MT version incorporates a tester device, enabling periodic functional verification without requiring actual level change in the separator. This supports maintenance and operational checks under controlled conditions.

Selection Considerations

Selection should be based on separator type, fuel compatibility, actuation level, flange connection, tester requirement, and compliance with fuel system specifications. For retrofit, verify available space for float movement and tester access.

Maintenance

Inspection includes free float movement, tester operation, chamber cleanliness, flange sealing, and response to actual or simulated level changes. For systems with water, sediment, or microbial contamination, regular cleaning is required to prevent altered actuation points due to deposits.
