HB Series Hydraulic Hose Break Valves are used to prevent the uncontrolled descent of load in case of hose breakage.
Cartridge type valves are mounted directly into the port of the cylinder and inline valves are mounted directly into the cylinder.
Hose break valves are normally open during operation. If fluid flows in the reverse direction and flow exceeds setting value of the valve, the closing disc will shut the flow by pushing valve seat.
