SCHROEDER AR VALVESIP Series - For High Pressures

BRAND: SchroederCATEGORY: Pump Protection Valves

The SHP Automatic Recirculation Valve (ARV) also known as a Leak Off Valve at Eskom, is designed to provide pump protection for high pressure high value pumps within Eskom power stations. Damage can occur when the flow rate falls below the required minimum.

“Reliable Pump Protection”

The innovative design ensures that these pumps are reliably protected, even in situations involving highly fluctuating pump loads and long periods of operation under extreme partial load conditions. This is achieved using a special fully automatic minimum flow control system that ensures that flows never fall below the required minimum as specified by the pump manufacturer.

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

This makes the SHP Series the ideal valve for applications involving very flexible operating conditions as found in modern power stations.
