When and How to Adjust a Load-sensing Hydraulic Pump
Adjusting a pressure-compensating pump is quite simple. With all flow blocked and the system idle, the compensator valve is adjusted to the desired pressure. However, some pressure-compensating pumps have two valves mounted on the pump body. The two adjustments can look nearly identical. This type of pressure-compensating pump is called a load
