ROV valve pack HLK-73300

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 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 4 and 6 way configurations utilise 5 and 7 port manifolds respectively and are fitted with an additional tandem cen-tre cartridge to allow an open centre flow path within the manifold in an idle state. This provides a system or pump un-load function to aid in power management within the hydraulic system power architecture. When the tandem valve and work valve are switched simultaneously the flow from the tandem valve is directed to a blind port within the manifold to allow system pressure to be achieved. Features • - Dual pilot operated check valve on each port • - Custom banjo containing needle valve on each work port • - Four available configurations: 4 way with bypass, 5 way, 6 way with bypass and 7 way • - Compact & lightweight • - Pressure tolerant electronics tested to a depth of 3000msw • - 4:1 Check valve pilot ratio
