Air Cylinder, Fifth Wheel King Pin Release Valve
SAF-Holland

Air-actuated cylinder that drives the release mechanism of the fifth-wheel king-pin connection. The unit is designed to withstand regular hitching and un-hitching cycles under pressurized air up to 200 psi, and to operate across a wide temperature range from -40 to 80 degrees Fahrenheit. Built from anodized aluminum, the cylinder delivers corrosion resistance and low weight, improving service life in the field. The valve actuator is engineered to produce smooth stroke and reliable retraction, which reduces cycle time during connector operations and contributes to operator safety through predictable action. Within category 42814 and VMRS 059-001-165, it integrates with SAF-Holland's release-valve assemblies and king-pin mechanisms, offering compatibility with standard fittings and hoses used in heavy-duty trailer systems. The Prop 65 warning label is included on the packaging, reminding maintenance personnel to follow handling guidelines when identifying defects or during routine replacement. This component enables efficient hitching by providing rapid, controlled release of the locking mechanism, while maintaining the durability required in demanding road conditions.
