Dual Check Valves

Dual locking valves lock air in two directions, to prevent bounce and runaway cylinders. Locking air on both sides of the cylinder piston results in better control when stopping. No external pilot lines.

Advantages:

Holding position, less bounce, avoid equipment crashes with flow control option, leak testing.
