The line rupture safety valve, which is generally mounted directly on the consumer (cylinder)serves to block a consumer in the event of a break in a pressurised pipe, i.e. if the hydraulic counter pressure subsides. It therefore prevents an uncontrolled decline in the load. A flow in excess of the setpoint results in a shim that has been lifted off the valve seat with spring force being pressed onto the housing seat by the flow forces, and consequently the valve closes.
Two versions – one for completely stopping the load and one with an orifice hole for a slow decrease – enable this valve to be used for various requirements.

■ Pressures up to 700 bar
