As part of a drive to develop innovative and reliable products to meet new customer requirements, Hydro-Lek have updated the design of their 7-way valve pack to ensure ease of use and maintenance and greater flexibility, with a significant saving in weight.

A major new feature of the HLK-73300 is the replacement of o-rings and taper-threaded fittings with parallel-threaded fittings and Dowty seals, enabling a fast, easy and oil-tight connection to a wide range of fitting types including Quick Disconnects. In addition, new captive flow adjusters allow easier fine tuning of valve flow settings – and full control of manipulator movement - without the risk of fully removing and losing the adjustment screw.

A wide number of variations of the valve pack are available and customers can select from numerous system options including polarity, output function fittings, supply input fittings and coil voltage. Two additional ports allow a second HLK valve pack to be connected as a slave where more than 7 bi-directional valves are required.

The HLK-73300 is also available as a 5-way valve pack and as a 4- and 6-way with bi-pass valve.

Hydro-Lek valve packs are used widely within the subsea industry for controlling the operation of tooling skids on a variety of ROVs worldwide.

Hydro-Lek is a leading supplier of remote handling systems for the subsea, nuclear and defence industries. The company was acquired by Saab Seaeye in 2013 and produces a range of hydraulic intervention tooling from simple hydraulic components to fully integrated telemetry-controlled remote manipulator systems for integration onto ROV’s and remote access platforms worldwide.
