1 / - way cartridge valve type URZS/S NS, 0, 50 up to MPa up to 00 dm /min DT SHEET - SERVICE MNU NUL WK PPLICTIN / way cartridge valve type URZS S can be used in hydraulic systems as a pilot operated check valve or by combination of several elements as a multiple directional control system. DESCRIPTIN F PERTIN URZS 0 C 05 E 1/S / way cartridge valves comprise the cartridge assembly and the cover (1) with control bores. The cartridge assembly is composed of the sleeve (), the spring () and the poppet (5). The valve poppet (5) is held on its seat by means of the spring (). The valve allows for free flow from to or reversely from to. The valve poppet is graded. There are three important surfaces for its operation. The area seat 1 is assumed as 100%. The annulus area, resulting from the grading is 100% 0% of area 1, the area ratio 1 : is therefore 1:1 :1. The area is 1 + and is 00% of area 1. The valve opens in both flow directions if the surface is not affected by pressure (the port is without pressure) and pressure force acting on the adequate surfaces 1 or exceeds the spring force (). If control pressure affects surface, then the poppet is pushed onto its seat irrespective of the spring force (). The valve may be opened by unloading surface or by suitably high pressure in port or. The orifice insert () fitted in port allows to select the opening curve and the valve opening time. 1 5 NTE: 1 (100%) The valve cover (1) must be ordered separately. (100% 1) (00% 1) Type URZS/S WK
