RSE and RSG Pipe rupture valves
6.1 General:
• Type: plate valve
• Mounting method: screw-type cartridge
• Ports: P, Z see point 10
• Mounting position: any
• Weight: see point 10
6.2 Hydraulic characteristics:
• Size: 1/4, 3/8, 1/2, 18x1,5

• Hydraulic medium: mineral oil per DIN 51524 and
DIN 51525 (HL/HLP),
inquire about other media
• Hydraulic medium
temperature range: -20°C...+80°C,
inquire about other temperatures
• Viscosity range: 2.8 mm

• Filtering: NAS 1638 class 9, β10 ≥ 75.
• 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 plate is forced against the valve
seat and seals the opening passage leakfree.
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
hose burst occurs.
• settable closing flow

4. Functional description, sectional view
6. Characteristics
• simple adjustment of flow rates
• minimal spatial requirement thanks to compact design.
2. Advantages of Beringer's pipe rupture valve
• 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.
• Observe the tightening torques (see dimension diagram).
• Bleed the hydraulic system before putting it into operation.

1. Screw in the sealing plate until it sits on the seat.
2. Set the flow acc. to the setting diagrams (see section 11).
3. Tighten the lock-nut to the specified torque (see section 10).
