1 180 Series Rotary Shear Directional Control Valve Up to l 38 lpm, 10 US gpm l 700 bar, 10,000 psi Milwaukee, WI 53235, US el: +1 (414) sales-us@webtec.com St. Ives, Cambs. E27 3LZ, UK el: +44 (0) sales-uk@webtec.com he 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. he valves utilise an optically flat rotary spool with pressure loaded seats, to ensure either zero or near zero leakage. hey have excellent tolerance to contaminates. orting: See able 2, ordering codes Material: Steel components in an luminium body. Nitrile rubber (NR) seals. Weight: ypically 1.4 kg, 3 lbs Mounting: See tables 2 & 4, ordering codes Features l 6 centre conditions l 3 position / 2 position l Flow throttling capability l Zero leakage l Spring to centre or detent action l osition lock version available (button or removable key type) l ressurised tank port with additional drain available l Express build available (single unit orders) Symbol: e.g 183 Certificate No.8242 Hydraulic measurement and control 180VLVE-U-ENG-1987.pdf 02/17 (Issue 17)

3 orting Codes E, L, & orting Code orting Code C orting Codes M & U CEO3/D03 interface Manifold mount type (M & U, able 2 of Order Code) hese manifold mount valves have interfaces compatible with CEO3/D03 standards. he end user should note that the overall width of the valve assembly exceeds that required by the standard. CEO3 (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. oth port types are supplied with 4 x S ISO 3601, S NR O rings, & with additional instructions. Leakage between flow paths. Closure tests with low pressure air (82 psi) were conducted on Webtec s 180 Series of rotary directional control valves. Flow size 0 with non-interflow was found to have no visually detectable leakage for the duration of the test (60 seconds). Flow sizes 1 & 2 with interflow were found to have a leakage of 1.67x10-4 lpm which equates to less than 1 drop of water every 10 minutes. Note: he performance of the valve in terms of leakage across paths is adversely affected by a reduction in fluid viscosity Handle osition he handle can be re-assembled through 180 degrees. his minimizes the pitch between banked valves (16mm, 0.63 straight handle, 14mm, 0.55 bent handle) Left position 16 (0.63 ) 16 (0.63 ) Centre position 180 degrees Right position ank ort ressure Maximum tank port pressure 17 bar, 250 psi, unless ank port pressurised option ordered.
