Catalog HY14-255/US Technical Information General Description sandwich type pressure s are typically used in combination with proportional directional control valves. The keeps the pressure drop over the directional valve constant and thus provides load-independent flow to the actuator. Features 2-way or 3-way pressure s. Standard pressure differential 5 ar (73 ). Adjustable differential (2 to 5 ar) (29 to 73 ) and 1 ar (145 ) optional.
