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.

¹) Only external seals for 10 valves
