Product description
Designed for higher capacity in-ground lifts, this SVI International 3″ core valve is a versatile replacement for both Weaver and Rotary systems. It is the direct-fit equivalent for OEM part numbers EC-106 and A-1842. This valve is engineered to handle the increased flow demands of large hydraulic cylinders, ensuring that even heavy vehicles can be lifted steadily and efficiently. A worn or leaking 3″ valve can compromise the lift’s ability to maintain a level position under load, which is a major safety concern. SVI uses premium materials and precise machining to create a core that provides an exceptionally tight seal and responsive control. Upgrading to this USA-made SVI part is a reliable way to extend the working life of your high-capacity in-ground hoist.
