Central block for switching Load-Sensing and constant current

Central blocks are offered here for switching between load-sensing and constant-flow operation for closed-center blocks. The switching is performed via the handwheel.

It also allows, by wiring the seat valve, the generation or simulation of an LS signal. Damping and relief of the LS signal are already integrated. An adjustable pressure limiter for the LS signal is also integrated.

Technical data:
- max. allowable pressure: 350 bar
- adjustable max. LS pressure: 100-290 bar
- max. flow rate in constant-flow operation: 120 l/min
- max. flow rate in LS operation: up to 250 l/min
- switching voltage: 12 VDC
- P ports: 1x 3/4" BSP and 1x 1/2" BSP
- T ports: 2x 3/4" BSP and 1x 1/2" BSP
- LS port: 1/4" BSP (3x)
- standby pressure in constant-flow operation: approx. 14 bar (recirculation pressure)
- standby pressure in LS operation: dependent on the supplying pump (e.g., tractor)
- material: ductile cast iron with phosphating according to DIN EN ISO 9717

Delivery includes LED magnetic connector for the seat valve.
