The automatic recirculation control (AR) valves from our SSV series automatically protect centrifugal pumps against wear, total loss and damage, which can occur due to dry running or during low-load operation. Our recirculation valves have historically proven exceptional reliability and low pressure loss over time. They are not susceptible to interference and are very low maintenance. In addition, they require no additional power supply or any kind of control unit, thus ensuring low operating costs.
The properties of the SSV valves make them the ideal fitting for the protection of pumps in the following fields of application:
