Product Overview

The CCMY8500M3 is specifically developed for ground aviation refuelling operations, providing precise downstream pressure regulation regardless of inlet pressure or flow conditions. The air-referenced pressure control system maintains consistent delivery pressure, protecting aircraft fuel systems while ensuring efficient refuelling performance.

An integrated pressure relief valve automatically releases hydraulic lock during coupler closure, improving operational reliability and extending component life.

Benefits

Improved Refuelling Safety

The integrated deadman pressure control system ensures controlled fuel delivery while preventing pressure surges that could damage equipment or compromise safety.

Consistent Pressure Control

Designed to regulate downstream pressure independently of supply pressure, the CCMY8500M3 delivers stable performance throughout the refuelling process.

Reduced Maintenance Downtime

The coupler can be fully serviced from the API connection without removing the pressure control assembly. The nose seal can even be replaced while the unit remains under system pressure, reducing maintenance time.

Durable Construction

Manufactured primarily from high-strength aluminium alloy and stainless steel with corrosion-resistant components, the CCMY8500M3 is built for long service life in demanding airport environments.

Secure Locking Mechanism

A six-catch locking and interlocking system provides a positive connection between the pit valve and coupler. The poppet valve cannot open unless correctly connected, preventing accidental fuel release.
