Description

The line rupture protection valve type LB offers a high level of safety in the event of pressure peaks. It features reproducibly accurate and secure closing at the pre-set trigger flow rate. Higher flow rates cause a plate raised from the valve seat by a spring to be pressed onto the housing seat by the flow forces and cause the valve to close. A variant with orifice bore in the valve plate permits a low flow rate in the locking direction. Type LB is available as a screw-in cartridge in a housing version for in-line installation, or as a screw fitting version. Features and advantages Reduction in screw fittings in the case of E-version Maintenance free Pre-adjusted valves available Different sizes and designs available Intended applications Industrial vehicles Lifting devices
