Schroeder Automatic Recirculation Valve (ARV) Valves also known as Leak Off Valves at Eskom. They automatically protect high pressure multi-stage centrifugal pumps against overheating, wear, cavitation to total loss and severe damage, which can occur during dry running or during low-load / low-flow operation.

“Reliable Pump Protection”

Should the flow through the pump fall below the required minimum as specified by the pump manufacturer the bypass system opens and the process liquid is recirculated providing the required minimum flow protection for the pump. Schroeder valves have historically proven to provide exceptional reliability and low pressure loss over time. They are not susceptible to interference and require very low maintenance.

Our Valve Repair Centres in Secunda and Durban provide a full valve repair and reconditioning service.

In addition this purely mechanical device does not require external power or any kind of control unit, thus ensuring low operating costs and low Total Cost of Ownership (TCO). Eskom, Sasol, Sulzer, KSB, Weir, Flowserve and many others rely on Schroeder to protect their multi-stage boiler feedwater and process pumps.
