Key Features
- Genuine OEM Quality — Manufactured by Genie to original design specifications, ensuring dimensional accuracy and material grade consistent with the factory-installed component.
- Direct OEM Replacement — Designed to install in place of the original piston with no modification, maintaining the integrity of the check valve assembly it serves.
- Broad Fitment Across Large Boom Models — Compatible with Genie SX super-boom telescopic lifts and Z/ZX articulating booms, covering high-capacity models including the SX-150, SX-180, Z-135/70, and ZX-135/70.
- Maintains Controlled Fluid Flow — A correctly functioning pilot operated check piston holds load and allows controlled release only when commanded, supporting predictable boom movement and safe load holding.
A pilot operated check piston is the internal moving element of a pilot operated check valve — a valve that allows fluid to flow freely in one direction but blocks reverse flow until an external pilot signal releases it. This arrangement is used on boom lifts to hold a loaded circuit in position, preventing unintended movement under load. When the piston wears, sticks, or seats improperly, the valve may fail to hold position or release erratically, leading to uncontrolled boom drift and unsafe operating conditions. Replacing a faulty piston with the correct OEM component restores the valve's intended holding and release behavior.
