5 PSI Check Valve 27836GT / 27836 (Hydraulic Low-Pressure Check Valve) – Optimized Product Page Content

🔹 Product Overview
The 5 PSI Check Valve with part numbers 27836GT and 27836 is a small but critical passive component used extensively throughout the hydraulic circuits of various Genie Boom Lifts. A check valve’s primary function is to permit hydraulic fluid flow in only one direction while blocking flow in the opposite direction. This particular valve is specified with a 5 PSI cracking pressure, meaning the fluid pressure must exceed 5 PSI before the valve opens to allow flow.
This low-pressure check valve is typically used in pilot lines, return lines, or specific low-pressure circuits to maintain back pressure, prevent fluid drain-back, or ensure proper sequencing in complex manifolds. The part number 27836GT is the necessary replacement for addressing subtle hydraulic issues such as erratic control signals, excessive system noise, or slow response in circuits where maintaining a minimum back pressure is essential.
🔹 Key Features & Benefits
✅ One-Way Flow Control: Ensures hydraulic fluid travels in the correct, intended direction only.
✅ 5 PSI Cracking Pressure: Maintains a precise, low level of back pressure in the circuit for optimal component performance.
✅ Broad Boom Lift Fitment: Used across a wide variety of Genie S-Series and Z-Series Boom Lifts.
✅ Direct OEM Cross-Reference: High-quality aftermarket equivalent for Genie part numbers 27836GT and 27836.
