AUTOMATIC RECIRCULATION VALVES

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.

The SR/SA valve type has been designed to control liquid media at high and very high pressures. The control valve is able to safely withstand pressures up to 600 bar and media temperatures of up to 400 °C. It is suitable for use both as a stand-alone shut-off valve (type SA) as well as for flow-control (type SR).

Multiport throttles are used to reduce the pressure and flow volume of liquid media. The multiport throttles are used in nominal widths ranging from DN20 to DN500, in pressure steps up to PN640 and up to a permissible media temperature of 400°C. The throttle housings are normally made of 1.0460 (C22.8) steel suitable for pressurized vessels, but can also be made of various types of stainless steel, depending on the medium.
