Introduction
Pressure control
The Pressure control establishes the final output pressure to the grips. It works in
conjunction with another pressure reducing valve which is being used as a
pressure relief valve. These two valves work in the same fashion as the valves on
the supply manifold.Each Grip has its own independent pressure control valve
and safety relief valve.
Grip control
The grip controls port the final output pressure to the grips. Each grip has two
port: a grip port and a release port. The grip controls change the output pressure
from the grip port to the release port and vice versa. The controls also have a
midpoint where the hydraulic pressure is stopped at the grip control; this causes
the grip to stop its hydraulic movement.
