RSP / RSW / RSPR and RSWR Pipe rupture valves
6.1 General:
• Type: ball-seat valve
• Mounting method: screw-type cartridge
• Ports: P, Z see point 10
• Mounting position: any
• Weight: see point 10
6.2 Hydraulic characteristics:
• Size: 8, 12, 16, 20, 25, 32
• Min. settable
closing flow: 5 l/min (NW8)
• Max. settable
closing flow: 580 l/min (NW32)
• Max. working pressure: 400 bar
• 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
2
/s up to 380 mm

/s
• 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 ball 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
1. General description
3. Application
4. Functional description, sectional view
• leakfree closing
• simple laying of pipework
• minimal spatial requirement thanks to compact design
2. Advantages of Beringer's pipe rupture valves
• This valve must only be used for the purpose for which it has
been designed.
• It must only be adjustment 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 against becoming damaged.
• Observe the tightening torque (see dimension diagram).
• Bleed the hydraulic system before putting it into operation.
• Fix the pipes in position in such a way that radial forces do not
act on port Z.
