A pilot circuit kept fully separate from the main circuit makes commissioning predictable. On this valve pilot oil supply and return both run externally at a nominal flow of 360 l/min. The command value is 4 to 20 mA, permissible operating pressure is 350 bar.

A pilot circuit kept apart from the main circuit makes commissioning predictable, because pilot pressure and working pressure can be set independently, here at 360 l/min nominal flow.
Key benefits
- Pilot oil routed entirely externally, pilot pressure and working pressure can be adjusted and measured separately.
- 360 l/min nominal flow in a body rated for a maximum flow of 1600 l/min.
- 4 to 20 mA current command, 24 VDC supply through a 7-pole connector (6 + PE) to EN 175201-804.
- Spool symbol W8 with 3 switching positions on 4 ports, interface ISO 4401-10-09-0-05.
- 43.76 kg installed mass, integrated pressure reducing valve, NBR seals for HL hydraulic fluid.

Applications
The combination suits test rigs, special purpose machines and first commissioning, where the pilot circuit is checked on its own first. Later fault finding also stays clear because pilot pressure is available at its own ports. Permissible operating pressure is 350 bar.
