Abstract

The invention concerns a pump-protecting valve (1) having a valve housing (2), a pump connecting sleeve (4), arranged in a main passage direction (3), and a feed-water connecting sleeve (5) opposite the pump connecting sleeve. A non-return valve disc (10), which is possibly spring-loaded, is mounted so that it is axially displaceable between the pump connecting sleeve and the feed-water connecting sleeve. The non-return valve disc (10) actuates an at least single-stage throttle valve (11) which is coaxial thereto, so that this throttle valve (11) is fully open when the non-return valve disc (10) is closed and produces a bypass from the pump connection side to a bypass connection (12) disposed laterally of the main passage direction (3). The valve housing (2) has an assembly plate closure (20) opposite the bypass connection (12). The non-return valve disc (10) and the throttle valve (11) are removably mounted coaxially to the assembly plate closure (20).
