The OPW 66SP High-Volume Breakaway is a robust, safety-critical component designed for diesel train refuelling operations within the railway industry. It is ideally suited for installation on high-capacity fuel dispensing hoses used at rail depots and service facilities, where flow rates are substantial and spill risk must be tightly controlled.
Using shear pin technology, the 66SP separates cleanly under excessive pull force—protecting both personnel and equipment while minimising fuel loss. Unlike traditional breakaways, it is engineered to prevent unintended valve closures that could interrupt fuel flow. After separation, the unit can be easily and quickly restored to service using the OPW 66PRK Shear Pin Replacement Kit.
The breakaway’s red anodized aluminum body is designed to withstand the harsh environmental and mechanical demands of rail depot environments. Its internal low pressure drop valve supports optimal flow rates, ensuring fast, efficient fuelling of diesel locomotives.
Specific variants include fluorosilicone O-rings to enhance resistance to fuel exposure and temperature extremes, ensuring reliability in high-throughput railway applications. With a working pressure of up to 50 psi (3.45 bar), this breakaway valve is a dependable choice for high-volume rail refuelling systems.
