摘要
The coaxial valve housing (1-3) contains a setting valve (V) with axial movement, with a seal (13) directly at the valve member (V). A non-return and overpressure valve gives a medium flow into a zone round the coaxial valve to compensate for a pressure difference between the inlet and outlet The coaxial valve has a housing (1-3) containing a setting valve (V) with axial movement, with a seal (13) directly at the valve member (V). The medium flow through the outlet (A) passes through a non-return or overpressure valve, into the zone (U) surrounding the valve (V) if the pressure at the outlet connection (A) of the coaxial valve is greater than in the surrounding zone (U) or the pressure difference between the outlet connection (A) and the zone (U) is over a given threshold value. The setting valve is a rubber lip ring.
