Check Valve 94757 / 94757GT (3 PSI Low-Pressure Control) – Optimized Product Page Content
🔹 Product Overview
The Check Valve with Genie part numbers 94757 and 94757GT is a fundamental, passive hydraulic component used extensively throughout the hydraulic circuits of various Genie Aerial Work Platforms (AWP). A check valve is essentially a hydraulic one-way street: it allows hydraulic fluid to flow freely in one direction but completely blocks flow in the opposite direction. The 3 PSI specification refers to the nominal cracking pressure—the minimum pressure differential required to open the valve and allow flow in the intended direction.
This low cracking pressure valve is typically used in return, drainage, or specific pilot lines where minimal resistance to forward flow is desired, but backflow must be strictly prevented. The part number 94757GT is the necessary replacement for addressing issues such as a failure to hold fluid (leakage backflow), or complete blockage of flow due to valve failure or contamination.
🔹 Key Features & Benefits
✅ One-Way Flow Control: Allows fluid flow in one direction only, preventing unwanted backflow.
✅ 3 PSI Cracking Pressure: Low pressure requirement to open, suitable for low-resistance flow paths.
✅ Passive Reliability: Operates without electrical input, relying only on hydraulic pressure differential.
✅ Direct OEM Cross-Reference: High-quality aftermarket equivalent for Genie part numbers 94757GT and 94757.
