The valve housing (1) is a hollow body which has two vertical sleeves (2, 3) for the water pipes at the bottom of the housing and a third connector (12) at its side for connection to the radiatior. The connector from the radiatior can be connected to the water pipes via two horizontal parallel channels (4, 5). A cylindrical hollow space (6) is formed above one of the water piped connecting sleeves. A valve body is mounted in this hollow space. The valve body has one through opening which is in line with one of the horizontal channels from the radiatior connection and a second through opening which can be brought in line with the second horizontal channel. The valve further has a cylindrical cut-out which extends to the bottom valve seat.</p> |
