Spool Type, Pilot Operated, SAE-16 Cartridge - DB16SPF

The pressure relief valve DB16SPF is a pilot operated, spool valve with a remote control option via the additional port 3.

Therefore, if the pressure across port 1 exceeds the pre-set value, the pilot-stage opens and oil flow from behind the main spool to the tank port 2. Then, the resulting pressure differential allows the main spool to lift against the reset-spring and allows the oil to flow from port 1 to port 2. Additionally, the valve may switch the system to unpressurized flow by draining a flow over port 3.

Features:

• Additional port for remote control option, e.g. in combination with a solenoid valve
• It's possible to switch the system to unloaded flow
• Quick response
• Good stability across the whole pressure and flow range
• External surfaces zinc-plated and corrosion-proof
• Hardened and ground control piston to ensure minimal wear and extended service life
• Adjustable throughout flow range
• Finally, there are different pressure ranges up to 350 bar available
