摘要:
The present invention relates to a check valve and a valve system involving a check valve designed in such a way that a topping piston (92) can be placed against a main taper (72) to eject same from the valve seat (76). The main taper (72) is designed in such a way that it present no surface variations, and the topping piston (92) can be actuated through a pilot valve (10) so that the ejection of the pilot valve (10) may be controlled by the valve seat.
