Pressure control valve

摘要

The valve has a valve housing (11) comprising a housing lower part and a housing cover (13). A diaphragm valve body is clamped in a groove between the cover and the lower part in a sealing manner. The valve body divides the housing into a valve chamber (29) and a ventilation chamber that is connected with the atmosphere over a ventilation channel. A diaphragm (14) has a valve plate (19) that is attached to a valve seat, and a pressure spring (25) is supported at a base of the lower part. A flow deflection device (27) is connected with the valve plate in a detachable or non-detachable manner.
