The Genie 27836GT is a genuine OEM Check Valve, 5 PSI designed for a wide range of Genie telescopic and articulating boom lifts. Sourced directly from Genie, this part matches the original component in cracking pressure, port size, and construction — so it installs into the hydraulic circuit exactly as the factory intended. Compatible models include S and SX series telescopic booms such as the S-40, S-60 XC, S-85, S-100HD, SX-105 XC, SX-135 XC, and SX-180, as well as Z and ZX series articulating booms including the Z-34/22 IC, Z-45/25J IC Power, Z-62/40, Z-80/60, and ZX-135/70. Cross-reference part number 27836GT against your Genie parts manual to confirm fitment for your specific serial range before ordering.
Key Features
- Correct Cracking Pressure — Rated at 5 PSI to match the original hydraulic circuit specification, ensuring the valve opens and seats at precisely the right threshold.
- Genuine OEM Construction — Manufactured to Genie's own standards with materials selected for hydraulic-fluid compatibility and long service life under continuous cycling.
- Direct Hydraulic-Circuit Replacement — Engineered to the original port configuration and thread spec, so this valve drops into the existing hydraulic plumbing without adapters or rework.
- Broad Boom Compatibility — Fits an extensive range of Genie S and SX telescopic booms and Z and ZX articulating booms, making this a high-utility part for mixed Genie fleets.
- Hydraulic System Integrity — A functioning check valve prevents unintended backflow that can cause platform drift, sluggish boom response, or pressure loss — keeping boom movements controlled and predictable.
- Aerial-Lift Safety Relevance — On boom lifts, uncontrolled hydraulic backflow is a platform-stability concern. Installing a correctly rated OEM check valve supports the hydraulic system's ability to hold load and position as designed.
A check valve is a one-way hydraulic component that allows fluid to flow freely in a single direction while blocking reverse flow when pressure drops or the circuit is at rest. In a boom lift, check valves are used at key points in the hydraulic system — including lift, extend, and stabilizer circuits — to hold cylinder position and prevent the platform or boom from drifting under load. When a check valve fails or wears out, the most common symptoms are slow or uneven boom movement, platform drift during operation, and a loss of holding pressure. Replacing a worn check valve with the correct OEM-rated unit restores proper flow control and helps the hydraulic system maintain the pressure levels needed for safe, predictable operation at height.
