The Rotary P414-5 hydraulic valve is the direct replacement for the Rotary lift it came off of. Cross-referenced as ALS-9772-39, it is the genuine Rotary part — same part number, same fit, and same working specification as the one already on your lift. Ordering the Rotary hydraulic valve from us gets you the OEM piece that matches the lift, not an aftermarket knock-off that is close but not the same.
Specifications
- Part number: ALS-9772-39
- Brand: Rotary
- Type: Genuine OEM hydraulic valve
The lowering valve (release valve, dump valve) is the solenoid or manual valve on the pump that opens to let fluid flow back to the reservoir when you lower the lift. When it fails it either leaks internally and the lift descends by itself with a car on it, or it sticks and the lift will not lower at all. Diagnosis: raise the lift to max height and watch. If it drifts to the locks in less than an hour with no external leaks, the lowering valve is the answer.

Check your lift's serial before ordering
The most common reason a lift part comes back is not a defect — it is a revision mismatch. Manufacturers change sub-parts between production runs while keeping the same lift model name, so "it fits my lift model" is not always enough. The model plate carries the serial number that pins your lift to a specific run, and that is the number that settles which version of this part belongs on your lift.
Can't find the plate? Measure the old part — overall length, bolt-hole spacing, thread size on anything threaded — and photograph it from a couple of angles. Send that with your lift's brand and rough age and we will match it against the parts breakdowns we service from every week.
Check while the valve is out
- Pump face and threads — clean, no burrs
- Solenoid coil and wiring (if electric) — melted lug ends, corrosion
- Handle and pivot (if manual) — not sticky, not bent
- Check valve, if separate — a failing check valve on the pressure side gives the same "lift drops on its own" symptom, so verify the lowering valve is actually the problem
The valve o-ring seals on hydraulic oil. Use ISO-32, ATF, grease, or vaseline as installation lubricant — not thread sealant, which will end up in the hydraulic system.
10 seconds on the release lever after the lift is down. Not 3, not 5 — 10. A pressurized valve backing out under impact torque will hurt someone.

If you also need companion wear items — cables, sheaves, seals, hardware — for the same repair, use our parts lookup and we will build the whole kit for your lift so you order once and finish the job.
About this p414 suction pipe
The p414 suction pipe is a direct-fit replacement engineered to restore original manufacturer performance on the lift model it services. Every piece we ship carries the exact dimensional and material specifications the OEM published for that application. Fitment on this component is critical: it interfaces with adjacent hardware in ways that any deviation from spec can drive premature wear on nearby parts or trigger the lift's mechanical safety systems into an unexpected condition. Shops that source this from us instead of a generic aftermarket substitute consistently report zero fitment issues on first-time installation.
Technical specification & installation notes
Technical specification matches the OEM published dimensions to within manufacturing tolerance. When a shop installs the p414 suction pipe correctly, the lift returns to factory-rated performance immediately — no break-in period, no cycle-count adjustment required. The lift's safety systems (mechanical locks, hydraulic pressure relief, and electrical interlocks) treat a correctly-installed replacement exactly as they would treat a factory-original component during initial commissioning. That parity is what lets us honor warranty coverage without asking for the lift's full operating history.
Shipping & ordering
Shipping runs 3-5 business days on standard ground to the lower 48 states. Expedited overnight and two-day options are available; call 800-674-9302 before ordering to quote expedited freight. We stock the p414 suction pipe in Iowa and ship same-day for orders confirmed before 2 PM Central. Orders that come in later than that or on a Friday afternoon pick up on the next business day. A tracking number gets emailed to the address on the order the moment the package leaves our dock.
Warranty coverage
Every p414 suction pipe sold through Automotive Lift Services carries a one-year manufacturer-defect warranty. If it fails within that window due to a defect in material or workmanship, we replace it at no charge. Damage from improper installation, use outside the lift's rated capacity, side-loading, or modifications to the parent lift are not covered. The warranty is documented on your original order receipt — retain that record for the coverage period. To submit a warranty claim, contact us with the order number and a photo of the failure at [email protected].
Cross-reference & fitment
Cross-reference on the p414 suction pipe is straightforward: match the OEM part number from the lift's parts breakdown against the number on your original invoice. If the numbers match, the component fits. If your lift's parts breakdown lists a superseded or alternate number, we accept the superseded value on the phone as confirmation of fit. When a manufacturer has issued a running change during production, we track the change in our catalog so ordering by the older number automatically pulls the current-spec replacement.
