Load-Sensing Signal Amplifier (LS-Boost)

If the pumps deliver little or too little pressure at the requested power demand, this is often due to a comparatively high continuous unloading of the pump and a control signal from the control block that is too weak. This valve amplifies the flow rate of the control signal from load-sensing blocks to the pump.

The standby pressure is hardly affected by this; in practice, too low a flow rate is the bigger problem.

Technical data:

• Increase in standby pressure: 3.5 bar
• Max pressure: 350 bar
• Connections: 1/4" BSP
• Seals: BUNA N
• Material: Steel
  

Connection:

• 1=LS line to the pump
• 2=P line between P and control block
• 3= LS line from the control block
