The Genie 13222-4GT Relief Valve, 500 PSI is a genuine OEM hydraulic relief valve designed for the Z-30/20HD articulating boom lift. Sourced directly from Genie, this valve is built to the exact pressure specification required by the Z-30/20HD hydraulic system, ensuring the machine operates within its engineered pressure limits. Cross-reference part number 13222-4GT against your parts manual to confirm fitment before ordering.
Key Features
- Factory-Rated Pressure Tolerance — Calibrated to a precise 500 PSI relief threshold, matching the hydraulic system demands of the Z-30/20HD without the guesswork of an improperly rated valve.
- Genuine OEM Component — Supplied by Genie, this valve meets the exact material and performance specifications of the original part it replaces, delivering consistent hydraulic response.
- Direct-Fit Replacement — Engineered as a drop-in replacement for the Z-30/20HD, matching OEM port sizing and thread configuration for a straightforward installation.
- Hydraulic System Protection — A correctly functioning relief valve prevents pressure spikes that can damage pumps, cylinders, and hoses — keeping the boom circuit operating within safe working parameters.
- Critical Safety Function — On an articulating boom lift, proper hydraulic pressure regulation is directly tied to platform stability and controlled movement; a failed or incorrect relief valve can compromise both.
A hydraulic relief valve acts as a pressure safety gate within the machine's hydraulic circuit. When system pressure reaches the valve's set threshold — in this case 500 PSI — the valve opens to divert excess fluid back to the tank, protecting downstream components from pressure overload. When a relief valve fails, sticks open, or is set to the wrong pressure, the result can be sluggish or uncontrolled boom movement, component damage, or an inability to hold a load — all of which are unacceptable on an aerial work platform.
