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 force (1), generated by the actuation, acts through the lever (2), the tappet (3) on the ball (4) and presses it out of the valve seat (5). This is used to connect lines P and A, 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.
Depending on the arrangement of the valve seat (5) and ball (4) the valve will have the basic position normally closed (NC) or normally open (NO).
