RS 16/32 Pipe rupture valve
6.1 General:
• Type: direct operated seat valve
• Mounting method: screw-type cartridge
• Ports: P, Z see point 10
• Mounting position: any
• Flow direction: P è Z free flow
Z è P closing direction
• Weight: see point 10
• for protecting hydraulic consumers
• for direct installation in cylinders
4.1 If, when the oil is flowing from Z to P, the pressure difference in
the valve exceeds a value that corresponds to the preloading
pressure (approx. 1 bar), the poppet is forced into the conical
seat and seals the opening passage.
4.2 The pipe rupture valve is opened again automatically when the
pressure at port P is higher than that at port Z.
• prevents uncontrolled movement of the cylinder if a pipe or a
hose burst occurs
• settable closing flow
1. General description
3. Application
• either almost leakfree closing or slow lowering
• minimal spatial requirement thanks to compact design
2. Advantages of Beringer's pipe rupture valve
4. Functional description, sectional view
6. Characteristics
• This valve must only be used for the purpose for which it has
been designed.
• It must only be adjusted by trained staff.
• The hydraulic system must be depressurized and checked
before the valve is dissasembled.
• The valve must not be opened without the express permission
of the manufacturer.
7. Safety instructions
• Observe all port designations.
• Protect seals and flange surfaces against becoming damaged.
• Observe the tightening torques (see dimension diagram).
• Bleed the hydraulic system before putting it into operation.

1. Realease the locking pin.
2. Unscrew the setting ring until the poppet sits on the seat.
3. Set the flow acc. to the setting diagrams (see section 11).
4. Tighten the locking pin to the specified torque (see section 10).
9. Adjustment instructions
(Please contact Beringer if machinery is required for use beyond these
tolerances)
