SSV Series

Automatic Recirculation Valves SSV

With bypass throttles or bypass non-return valve

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.

Special Characteristics

Special Characteristics

  • Modulating and low-wear minimum volume controls as a result of the rotary valve design
  • Non return check-valve function in the main line prevents pump damage by back flow from the process line at shut-off and standby
  • Multi-level pressure and volume reduction in the secondary outlet ensures low cavitation levels
  • Self-actuated - no additional energy supply or measuring technology required
  • Low pressure losses
  • Vertical or horizontal installation
  • Internal components made of stainless steel
  • Reliable, with a long service life
