WANDFLUH solenoid valve, proportional flow control spool QSPPU10 series

 The Wandfluh ensures safe lifting, lowering, and holding of heavy loads, usually via a hydraulic loop with multiple valves. The newly developed QSPPU10 proportional flow control spool combines all of these functions in a single valve with a 78 "-14 UNF chamber. It has load compensation to maintain steady lifting and lowering speed, and a tight seat to prevent the stem from uncontrollably lowering load.
