HAWE North America Inc. Line Rupture Safety Valve LB 11

Description
The line rupture safety valves type LB are check valves. They are available as screw-in valves or with housing for in-line installation. The line rupture safety valves are best installed directly on the actuator (cylinder) which is to be safeguarded. This will prevent an uncontrollable, accelerated movement (drop) of a loaded cylinder, when the hydraulic back-pressure is lost as a result of a rupture of the pressurized line or pipe connection. When the flow through the valve increases above the pre-set limit, the flow forces will exceed the opposing spring force and the valve will block the flow immediately. The valve element in these valves is a shim. There are two different versions available. One valve design completely blocks the flow when actuated, whereas the other one allows a minimum flow (via an orifice) to slowly drop the load.
