Hawe displays new spool valve size

摘要

For the first time HAWE Hydraulics will present its proportional directional spool valve type PSL in the new nominal size 7. The PSL 7 is designed for applications such as mobile heavy load-carrying machines, pile-drilling machines and ship and railway cranes. The valve serves to control the direction of movement of hydraulic consumers and provide load-independent, stepless control of their speed. It has a flow of 264 US gallons/min (lOOOliters/ min), which can be fed in through one inlet section to allow parallel operation of several functions at full speed. A volume flow of up to 105 US gallons/min (4001iters/ min) is also available per function regardless of the load. The valve is manifold mounting, enabling the individual spool valve sections to be changed easily without the necessity to disconnect the consumer lines.
