BENT-AXIS ACCESSORIES BY-PASS VALVE FOR ”HDS-MDS-HDT” SERIES

Note:
By-pass valve for pumps ”HDS-MDS-HDT” series

The bypass valve is used together with HDS bent axis piston pumps if the pump turns constantly when the vehicle is on (in installations with the power takeoff without a coupling or coupled directly to the motor). In such cases, all the oil flow delivered is circulated, at the maximum pump capacity permitted by the turning speed of the motor, through piping that is usually not sized for capacities greater than those required for the normal use of the pump, consequently giving rise to pointless energy losses and overheating in the system. The bypass valve serves the purpose of partially recirculating the pump’s oil flow.
