摘要: The invention relates to a valve (1) according the preamble of claim 1, in which seat contact surface (8) consists reinforcing alloy, particularly chrome-based, and being subjected wear during operation such that at least one worn region is produced. A housing (2), said (8), cover (13) with thickness (14) provided material allowance, body (5) form together first, maximum lift; when removed, can be removed lift remains same or only minor deviations; and/or (14), allowance deviations.
