Line rapture protection valves, type LB

Product description

Line rupture protection valves, also called pipe rupture protection valves are a type of check valve. The valves are normally mounted directly on the cylinder. They prevent uncontrolled cylinder movement in the event of a pipe rupture or hose break.

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 valve or in a housing version for in-line installation.

The line rupture protection valve type LB is used in industrial vehicles, lifting platforms and lifting equipment.

Features and benefits:
  • Pressures up to 500 bar
Intended applications:
  • Industrial trucks
  • Lifting devices
