The valve through which the gas is conducted has an inlet and an outlet. The valve body (2) is movably located in a housing, being forced to seal against a seat (7) by the effect of a spring (5) inside the valve housing. The quota between the force exerted by the spring on the valve body in the sealing position, and the movement path of the body from the sealing position to touching bottom under the effect of the external magnetic field is less than 2kN/m. |
