Description
Pilot flow is normally allowed bi-directionally between 1 and 2. When
pressure at 1 rises above the selected pressure setting, the ball check
seats and blocks flow from 1 to 2. The valve is intended to block
undesirable pressure spikes in pilot control systems, particularly in
counterbalance applications.
