Tradition and innovation go hand in hand at Hauhinco. Founded in 1908 in
Sprockhövel, Germany in the cradle of Ruhr mining, Hauhinco has remained
true to its roots – up to the present time. For over 100 years, the company
has adapted to many changes in structure and circumstances and continually
brought new, innovative products onto the market. This experience makes
Hauhinco unique in the market place.
Unsere technische Abteilung entwickelt kundenspezifische Wasserhydraulik-Lösungen und setzt mit ausgeprägtem Projekt Know-How, Kundenwünsche und Anforderungen exakt um.
Hauhinco is represented in a large number of industries with water hydraulic components and fluid system solutions.
Whether high pressure pump station or water spray pump station, with or without water treatment, we manufacture certified pump systems with all the necessary approvals for underground mines all over the world.
The increasing quality requirements of steel, stainless steel, copper and forged products simultaneously increase the requirements for the descaling process.
Along with control blocks (controls, manifolds), control technology and modular fluid systems, valves are among the most important components in water hydraulic installations.
The Hauhinco Service supports our customers all over the world with the commissioning, maintenance and repair of our high pressure plunger pumps, valves and water hydraulic systems as well as with the spare part identification and supply.
Hauhinco is a successful, medium-sized family business with a long tradition. Today the company is a leading provider in the area of water hydraulic applications. Our high pressure plunger pumps, valves and systems are used in underground in underground mining and industry all over the world. Our employees are the key to success.
Hauhinco has contact persons and representatives in all Mining and Industrial regions of the world.

The filling valve is used for the leak-tight blocking of low-pressure systems. Due to the large flow cross-sections it is particularly suitable for fast positioning movements with low pressure, primarily on press cylinders. During the high pressure stroke the valve remains closed.
The valve consists essentially of the housing (2), valve piston (5), valve seat (6), control piston (4) and a single- stage or multi-stage electrohydraulic pilot control system (1). All components are made of stainless steel or bronze and are easy to replace. The use of proximity switches (3) allows a monitoring of the switching points of the valve piston (5).
The home position of the valve (normally open or normally closed) is determined by the variation of the magnetoperated pilot valve.
In the basic position shown here, the continuously applied control pressure – via the closing surface of the control piston (4) – presses the valve piston (4) into the seat (6). If the actuation of the pilot valve applies additional control pressure to the opening surface of the control piston, the valve piston will open due to the existing surface ratios.
