5/7 Way Valve Pack

Product Overview

The HLK-73300 series general function valve pack is a cost effective and lightweight solution for the control of hydraulic Manipulators, Pan/Tilts, Rotary actuators and other types of hydraulic tooling. Rated for an operational depth of 3000msw, it is ideally suited for use on all types of submersible systems.

Every work solenoid has a dual pilot operated check valve inbuilt to the manifold for actuator position holding along with a custom Hydro-Lek banjo adaptor on both work ports. The banjo adaptor has an inbuilt needle valve with free reverse flow capacity to provide “meter-in” adjustability for fluids returning from an actuator.

The four and six way configurations utilise five and seven port manifolds respectively and are fitted with an additional tandem centre cartridge to allow an open centre flow path within the manifold in an idle state. This provides a system or pump unload function to aid in power management within the hydraulic system power architecture. Achieving system pressure requires switching of the tandem valve and work valve simultaneously, directing the flow to a blind port within the manifold.
