Dual Pilot Operated Check Valve 101958GT / 101958 (135 PSI) – Optimized Product Page Content

🔹 Product Overview
The Dual Pilot Operated Check Valve with Genie part numbers 101958GT and 101958 is a specialized, safety-critical hydraulic component used in the cylinder circuits of various Genie Aerial Work Platforms (AWP). This component serves two vital functions:
- Load Holding: It acts as a double check valve, locking the fluid in both sides of a hydraulic cylinder, preventing cylinder movement and load drift (especially under gravity).
- Pilot Operation: It requires a separate pilot pressure signal to open (unseat) the check valve and allow fluid to flow out of the cylinder. The specific 135 PSI setting likely refers to the pilot pressure requirement needed to open the valve, ensuring the cylinder remains locked until a control function is intentionally activated.
This valve is essential for ensuring that critical lift, steer, or extend cylinders remain safely locked when not in use. The part number 101958GT is the necessary replacement for addressing dangerous issues such as cylinder drift, uncontrolled movement, or a failure of the function to move (due to the pilot mechanism failing to unseat the valve).
🔹 Key Features & Benefits
✅ Dual Load Holding: Locks fluid in both sides of a double-acting cylinder, preventing drift and collapse.
✅ Pilot Operated: Requires a control pressure signal (likely 135 PSI) to open, ensuring intentional release.
✅ Safety Critical: Essential component for stability and load-holding compliance in boom and scissor lift cylinders.
✅ Direct OEM Cross-Reference: High-quality aftermarket equivalent for Genie part numbers 101958GT and 101958.
