Applications
High/Low Pressure Relief Valve
This D03 relief accessory can be combined with an AMT-PRC-**L to create a high/low relief valve with two independent relief settings.
Using a standard directional control with flow from “P to A” in the de-energized condition will select the relief setting of the cover. Energizing the pilot valve will switch the relief setting to the accessory. Note: The relief setting of the accessory MUST be lower than the setting of the cover.
The “Y” pilot can be connected to the “B” port but a separate drain connection is preferred. This configuration uses a 1:1 ratio insert.
