Control valves

The BERMAD 700 SIGMA EN/ES series are hydraulically operated control valves with high cavitation resistance and excellent flow capacity. The hydraulic parts can be removed from the body as a separate unit, which makes servicing easier. The seat design of the valves allows an unobstructed flow path and gives good capacity for applications with high differential pressure, with minimal noise and vibration. 700 SIGMA EN – Valve with full bore and high flow capacity. 700 SIGMA ES - Valve with reduced bore Technical data: Seat: Y-design Pressure class: PN10, PN16 and PN25 Connection: Flanges Plug types: Disc, V-port, cavitation protection Operating temperature: 60°C for cold water applications (higher operating temperatures on request)
