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 force (1), generated by the actuation, acts through the lever (2), the tappet (3) on the ball(s) (4) and presses it out of the right valve seat (5) and into the left valve seat (5). This is used to connect lines P and A and shut o line T, see Example. The ring (6) supports the fl ange seal from the inside. The volume fl ow is limited by the entire fl ow resistance.
The 3/2-way valve is provided with a „negative overlap“. During the changeover process, connections P, A and T are briefl y connected with each other. The changeover occurs so fast that the hydraulic effects are negligible. By design, a 3/2-way valve always requires the connection of a T-connector; only then a proper switching function can be ensured.
Depending on the design of the valve insert a valve with the basic position „AT NO“ (lines A and T are connected) or „PA NO“ (lines P and A are connected) is provided.
