Product description

The SVI International BH-9773-87 is a vital valve spring and disc kit for Rotary lifts using A.Y. McDonald oil control valves. These internal components are responsible for creating the final seal that holds the lift in place and prevents hydraulic fluid from bypassing the valve when it is in the neutral position. If the spring weakens or the disc becomes pitted, the lift may experience "drifting" or a failure to maintain its set height under load. This kit includes both the high-tension spring and the precision-ground disc, providing a complete solution to restore the shut-off capabilities of your FA369-5AY valve. Investing in this SVI part ensures that your lift remains stationary and safe during critical service procedures.
