Relief in Neutral
• This drawing shows the relief valve in action with the control valve in neutral.
• The relief action is the same no matter what position the control valve is in.
• If pressure builds beyond the pre-set limit, the relief valve opens, spilling fluid through a port that returns it
to the reservoir.
