摘要： A textile machine that produces take-up packages with control valves 1, whereby the control valves 1 each have a valve body 2, a piston 3 and a plunger 4, whereby the plunger 4 comprises a front seal seat 5 and a rear seal seat 6 as well as seals 9, with which outlets, such as a main line 14, a pilot line 19, a connection 16 and at least one vent 15 are alternately sealable in the valve body 2, and the piston 3 has a piston seal 8 that separates two air circuits from each other. Contact surfaces 11 are designed in the valve body, at which the corresponding surfaces 12 of the front and rear seal seats 5, 6 of the plunger 4 can be brought into abutment.
