HAWE directional seated valve does double duty

By Ken Korane | February 24, 2022

The new directional control valve type ROLV from HAWE Hydraulik is a directional valve and shut-off valve in one. With a CETOP 3 standard connection pattern it can be integrated directly into valve banks as a flexible control block. Connection blocks for direct pipeline installation are also available. In use, the machine designer and plant engineer benefit from leak-free, leak-tight holding in motion-control applications.

HAWE’s ROLV directional seated valve is rated for a maximum pressure of 5,800 psi.

These are several advantages of this design. The product offers potential savings in terms of the number of components required and, thus, in terms of installation space and installation costs. It offers significantly higher dirt resistance than that of directional spool valves, meaning high switching reliability. And the solenoid coil is exchangeable, for greater flexibility and easy servicing.

Directional seated valve type ROLV is rated for a maximum pressure of 400 bar and volumetric flow of 25 l/min. It available as a 3/2, 4/2 or 4/3-way directional seated valve with different plug types. The patented assembly consists of two parts: a round basic valve with the valve inserts, and an adapter plate which can be designed for manifold mounting with nominal size NG 6 as the standard connection pattern, or for direct pipe connection.

Additional elements such as a check valve, a restrictor (on the consumer side) and/or restrictor check valves can be integrated, depending on the functional requirement and adapter plate. The type ROLV can be combined in the valve bank type BA with other types of valves.

The valve is suited for a wide range of applications. These include machine tools (cutting and forming), clamping and punching tools, fixtures, test machinery and wind turbines.

Are hydrogen fuel cells the future for mobile machines? Prioritizing decarbonization is, without doubt, one that most countries agree with almost pure unanimity. Here, in the U.S., the Biden administration has a goal to eliminate carbons from the electric grid system by 2035. Globally, most countries are on similar timelines. But, looking ahead to 2050,…
