FIELD: manufacturing technology.
SUBSTANCE: invention relates to a valve mechanism, a metering valve with such a valve mechanism and to a dosing device with such a valve mechanism and/or such dosing valve. Dosing valves are part of dosing devices used for production of adhesive layers, filling applications or, in particular, foamed seals. Valve mechanism (10) for at least one liquid polymer component or liquid plastic comprises locking device, which for closing valve opening of valve mechanism has pressed to saddle (4) needle (5), wherein needle (5) and/or saddle (4) are made or installed are pliant.
EFFECT: invention provides wear resistance.
