Application
The valve protects circuits with large flow and low working pressure, such as cooling and circulation loops or clamping systems with a soft pressure build-up. Seat design keeps leakage low while pressure is applied. Subplate mounting to ISO 6264-10-17 allows replacement without reworking the piping.
