Forklift Adjustable Relief Valve – Directly Operated

Forklift Adjustable Relief Valve: Direct-Operated Hydraulic Pressure Control

This direct-operated adjustable relief valve provides hydraulic overpressure protection for forklift circuits. With a 1/4 inch port connection and tube body construction weighing just 0.3 kg, it installs directly inline or into manifold cavities on pump circuits, tilt cylinders, and attachment hydraulics. The adjustable set screw allows on-site pressure calibration from the working range up to 227 bar (3292 psi) maximum at 37.9 L/min (10 gpm) flow rate, making it suitable for 1-5 ton counterbalance forklifts.

The simple spring-loaded poppet design responds instantly to pressure spikes without pilot circuit delay, protecting hoses, seals, and pumps from overpressure damage. Operating on standard hydraulic mineral oil, this 2-way tube-style valve requires minimal maintenance beyond periodic set point verification. Common failure includes spring fatigue causing relief pressure drift and poppet seat wear from contaminated oil. Backed by a 1-year warranty.
