180 Series Rotary Shear Directional Control Valve Up to • 38 Ipm, 10 US gpm • 700 bar, 10,000 psi The 180 series of high-pressure aluminium hydraulic rotary shear directional control valves are the ideal solution for control of hydraulic actuators on mobile and industrial applications where internal leakage must be minimised. The valves utilise an optically flat rotary spool with pressure loaded seats, to ensure either zero or near zero leakage. They have excellent tolerance to contaminates.

CETOP3/D03 interface Manifold mount type (M & U, Table 2 of Order Code) These manifold mount valves have interfaces compatible with CETOP3/D03 standards. The end user should note that the overall width of the valve assembly exceeds that required by the standard. CETOP3 (M) type is supplied with 4 x M5 steel cap head screws. D03 (U) type is supplied with 4 x #10-24UNC steel cap head screws. Both port types are supplied with 4 x BS ISO 3601, AS568A – 011 NBR O’ rings, & with additional instructions. Leakage between flow paths. Closure tests with low pressure air (82 psi) were conducted on...
