在Hauhinco传统与创新是互不分离的。Hauhinco是1908年在德国斯普罗克霍威尔,鲁尔矿业的摇篮成立的。至今,Hauhinco仍旧牢记自己的由来。再过去的100余年间,公司经历了很多组织结构和市场环境的变化,并仍旧不断地推陈出新,为市场带来创新性的产品。这些经验使得Hauhinco在市场中独树一帜。
Hauhinco是一家拥有悠久历史的成功的中型公司。如今,Hauhinco是世界领先的水液压应用领域供应商。我们的高压柱塞泵,阀以及系统被广泛地应用于世界各地的井下煤矿以及工业领域。而我们的员工正是我们成功的关键。
The control pressure (X) for switching the valve is tapped internally from the system pressure in port A. The valve piston (2) guided within the Valve seat sleeve (1) is pressed into the valve seat (3) by the hydraulic power and the spring force generated by the control pressure (X) via the pilot valve (4) on the control surface (5). Thus, the lines (A, B) are separated.
By switching the pilot valve (4), the control surface (5) is depressurized and the hydraulic power along the lines A can be used to lift the valve piston (2) off the valve seat (3), i.e. as soon as the hydraulic pressure is applied to the lines A, the valve piston (2) moves into the opened position up to the mechanical end position. Thus, the lines (A, B) are connected.
The pilot volume in the control room is discharged to the Y line via the Y connection of the pilot valve (4). Depending on the function of the pilot valve (4), the basic valve position can be specified normally closed (NC) or normally open (NO).
