SHQ are flow  throtting valves, nor   compensated , and with  check valve  to allow free reverse flow. The flow adjustement is performed by turning the setting screw  .

Clockwise  rotation increases the throtting (passage reduced.)

 valve size and max flow: 

SHQ-0 : size 06, flow  up to  80 I/min 

SKQ-0 : size  10, flow up to   160 I/min
