Description
The pressure stage decides how precisely system pressure can be met. This pilot-operated seat valve is rated for 4 to 100 bar and passes up to 650 l/min to tank in size 32.
Benefits
- Setting range 4 to 100 bar for circuits in the lower pressure band, maximum operating pressure 350 bar.
- Relief flow up to 650 l/min in size 32 across 2 ports.
- Subplate mounting to ISO 6264-10-17, spool symbol B.
- Electrical unloading at 24 VDC, 2 switching positions, 3-pole connector (2 + PE) to EN 175301-803.
- 5.05 kg weight with NBR seals for HL hydraulic fluid.
- Internal hexagon with protective cap protects the pressure stage that has been set.
Application
The valve protects circuits with large flow and low working pressure, such as cooling and circulation loops or clamping systems with a soft pressure build-up. Seat design keeps leakage low while pressure is applied. Subplate mounting to ISO 6264-10-17 allows replacement without reworking the piping.
