Adjustment Procedure
The adjustment mechanism for Brand Hydraulics valves is generally similar across models. The exact tools and location may vary slightly, but the principle is the same.
The adjustment mechanism for Brand Hydraulics valves is generally similar across models. The exact tools and location may vary slightly, but the principle is the same.
- Locate the Adjustment Mechanism: Find the adjustment point on the valve body. This is typically a set xxxx concealed by an acorn nut or a protective cap to prevent tampering.
- Remove Protective Cap/Nut:
- For flow adjustment, you may need to remove a red rubber guard or an acorn nut.
- For relief pressure adjustment (if equipped), you will likely need to remove a larger acorn nut.
- Loosen the Locknut: A jam nut (locknut) secures the setting. Loosen this nut with a wrench to allow the adjustment xxxx to turn.
- Adjust the Setting: Use a screwdriver or an Allen wrench (hex key) to turn the inner adjustment xxxx .
- Clockwise rotation typically increases the pressure or decreases the flow (making the orifice smaller).
- Counter-clockwise rotation typically decreases the pressure or increases the flow.
- Make Incremental Changes: Turn the xxxx in small increments (e.g., 1/8 turn at a time). Large adjustments can cause significant changes in performance.
- Test the System:
- Start the engine and operate the hydraulic system to its normal operating temperature (typically 100-140°F).
- Use a pressure gauge or flow meter to accurately measure the results of your adjustment.
- Repeat steps 4-6 until the desired performance is achieved.
- Secure the Setting: Once the desired setting is reached, hold the adjustment xxxx in place and tighten the locknut securely against the valve body to prevent the setting from changing during operation.
