Abstract
A valve includes: a drive; a plunger connected to the drive; and two closing bodies connected to the plunger and movable by the plunger such that the two closing bodies are movable into abutment against respective sealing seats or away from the respective sealing seats. The two closing bodies are arranged fixedly on a sleeve, and the sleeve is slidable onto the plunger and connected fixedly to the plunger.
Claims2
A method for making a valve having:
- a drive;
- a plunger connected to the drive;
- and two closing bodies connected to the plunger and movable by the plunger such that the two closing bodies are movable into abutment against respective sealing seats or away from the respective sealing seats, wherein the two closing bodies (10a, 10b) are arranged fixedly on a sleeve (12), and the sleeve (12) is slidable onto the plunger (4) and connected fixedly to the plunger, the method comprising:
- welding at least one of the two closing bodies (10a) to the sleeve (12);
- sliding the sleeve (12) onto the plunger (4) until the at least one of the two closing bodies (10a) bears against the respective sealing seat (9);
- and subsequently
- welding the other of the two closing bodies (10b) to the sleeve (12) and connecting the sleeve (12) to the plunger (4),
- wherein the connection of the sleeve (12) to the plunger (4) is by the sleeve being pressed together with the plunger (4).
