Product description
The control valve is the heart of your Weaver in-ground lift’s hydraulic operation, and this SVI International 4″ core valve is designed for professional-grade systems. It serves as the primary mechanism for directing air or oil flow, allowing for precise control during both lifting and lowering sequences. A malfunctioning A-1877 valve can lead to jerky movements, inconsistent lifting speeds, or the inability of the lift to hold its position. This SVI replacement features a precision-machined core that ensures smooth actuation and an airtight/oiltight seal. By replacing a worn original valve with this USA-made SVI component, you restore the responsive handling and safety required in a fast-paced automotive shop. Its robust construction is specifically intended for high-cycle professional use.
