Abstract
In a valve the sealing disks in contact with one another consist of sintered silicon carbide ceramic and have on their functional surface a profile bearing percentage of at least 75% established by grinding and/or lapping and/or polishing. The mean roughness at the functional surface amounts to 0.01 to 0.1 .mu.m. The construction is especially suitable for a sanitary mixing faucet.
