A sealing device for an air valve, the sealing device comprising:
- a seat;
- a valve device configured to seal against the seat;
- a first contacting portion;
- and
- a second contacting portion;
- wherein a distance measured parallel to a central axis of the sealing device between a first mating surface of the sealing device and the first contacting portion is shorter than a distance measured parallel to the central axis of the sealing device between a second mating surface of the sealing device and the second contacting portion, each of the first mating surface and the second mating surface defined by one of the seat and the valve device.
A sealing device for an air valve, the sealing device comprising:
- a seat;
- a valve device configured to seal against the seat, the valve device being a poppet and comprising a guide shaft defining a bore extending from a bottom end of the poppet to a top end of the poppet;

A method for venting air from a fluid system, the method comprising:
- engaging a valve device of an air valve installed on the fluid system with a lever arm, the air valve comprising:
- a valve body defining an inlet and an outlet;
- a sealing device mounted inside the valve body, the sealing device comprising a first contacting portion and a second contacting portion and further comprising a first mating surface and a second mating surface;
- the lever arm coupled to the valve body;
- and
- a float coupled to the lever arm moveable within the valve body;
- moving the float to a first sealing position, the first mating surface of the sealing device contacting the first contacting portion but not the second contacting portion when the float is in the first sealing position;
- and
- moving the float to a second sealing position, the second mating surface of the sealing device contacting the second contacting portion when the float is in the second sealing position.
