SOB5A-CP3

1-1/16-12 UN • Q_max 80 l/min (21 GPM) • p_max 350 bar (5100 PSI)

• The valve prevents runaway ahead of the pump in the event of a negative load
• Load-holding with leak-free closing poppet when the directional control valve is in neutral position
• Pressure relief function protecting the actuator against overloading and pressure peaks
• Integrated check valve acting as an anti-cavitation valve
• When installed close to actuator the valve can be used as a hose burst valve
• Back pressure has got negligible effect on relief setting nor the required pilot pressure
• Setting can be performed during machine operation = leak free closing of adjustable element
• Wide range of relief pressure setting up to 350 bar (5100 PSI)
• In the standard version, the valve is zinc-coated for 520 h protection acc. to ISO 9227
