Central block for switching between load sensing and constant flow

Offered here are central blocks for switching between load-sensing and constant-flow operation on closed-center blocks. Switching is performed using the handwheel.

By configuring the seat valve, it also allows an LS signal to be generated or simulated. Damping and relief of the LS signal are already integrated. An adjustable pressure relief valve for the LS signal is also integrated.

Technical data:
- Max. permitted 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 connections: 1x 3/4" BSP and 1x 1/2" BSP
- T connections: 2x 3/4" BSP and 1x 1/2" BSP
- LS connection: 1/4" BSP (3x)
- Standby pressure in constant-flow operation: approx. 14 bar (circulation pressure)
- Standby pressure in LS operation: depends on the supplying pump (e.g. tractor)
- Material: cast steel with phosphating in accordance with DIN EN ISO 9717

Supplied with an LED magnetic connector for the seat valve.
