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 valve piston (1) is pressed into the valve seat (2) by the force of the spring (3). The control chamber (4) is connected to the A-channel via the control channels (5) within the valve piston (1). The hydraulic pressure supplied at the A-channel with the valve closed is thus also acting on the control surface (A2). This pressure keeps the valve closed and shuts off the direction of fl ow from the A- to the B-channel. Conversely, the non-return valve opens when the hydraulic pressure at the B-channel exceeds the hydraulic pressure at the A-channel and the spring force (3). In order to reach the initial opening of the closed valve, the hydraulic pressure within the B-channel must be greater by the factor of the control ratio A2/A1.
The valve piston (7) is adjusted by turning the hexagon (8) axially via the thread. By turning it clockwise, the valve is closed pressing the valve piston (7) into the valve seat (9). The valve piston can be fi xed via the locking nut (10).
