Commonly installed in hydraulic power units, machine tools, injection molding machines, presses, material handling equipment, and industrial automation systems using ISO 4401\/CETOP 3 mounting patterns. Maintenance technicians, hydraulic engineers, and \u003ca href=\"https:\/\/plgautomation.com\/collections\/hmi-operator-interfaces\"\u003esystem integrators\u003c\/a\u003e use this sandwich plate valve for hydraulic circuit protection, load holding, equipment repair, and replacement of OEM hydraulic check valves. The Z1S series features a compact sandwich plate design for vertical stacking assemblies and reliable hydraulic system performance. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5ms9th\" data-start=\"829\" data-end=\"846\"\u003eApplications:\u003c\/h3\u003e\n\u003cp data-start=\"847\" data-end=\"1347\"\u003eThe Uchida-Rexroth Z1S6P1-31-29 Sandwich Type Check Valve is commonly used in hydraulic manifolds, industrial presses, injection molding machines, machine tools, lifting equipment, mobile hydraulics, and factory automation systems where reverse flow prevention and leak-free hydraulic isolation are required. Its sandwich plate configuration simplifies installation between directional control valves and subplates while maintaining a compact hydraulic assembly. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5hg6bl\" data-start=\"1349\" data-end=\"1378\"\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cp data-start=\"1379\" data-end=\"2069\"\u003e• Brand: Uchida-Rexroth\u003cbr data-start=\"1402\" data-end=\"1405\"\u003e• Model: Z1S6P1-31-29\u003cbr data-start=\"1426\" data-end=\"1429\"\u003e• Product Type: Sandwich Type Check Valve\u003cbr data-start=\"1470\" data-end=\"1473\"\u003e• Valve Type: Direct-Operated Hydraulic Check Valve\u003cbr data-start=\"1524\" data-end=\"1527\"\u003e• Mounting Style: Sandwich Plate (CETOP 3 \/ NG6 \/ ISO 4401-03)\u003cbr data-start=\"1589\" data-end=\"1592\"\u003e• Nominal Size: NG6 (Size 6)\u003cbr data-start=\"1620\" data-end=\"1623\"\u003e• Flow Direction: One-Way Free Flow with Reverse Flow Blocking\u003cbr data-start=\"1685\" data-end=\"1688\"\u003e• Maximum Operating Pressure: 350 bar (5,076 PSI)\u003cbr data-start=\"1737\" data-end=\"1740\"\u003e• Maximum Flow Rate: 40 L\/min (10.6 GPM)\u003cbr data-start=\"1780\" data-end=\"1783\"\u003e• Cracking Pressure: 0.5 to 5 bar (configuration dependent)\u003cbr data-start=\"1842\" data-end=\"1845\"\u003e• Mounting Pattern: ISO 4401-03-02-0-05 \/ NFPA D03\u003cbr data-start=\"1895\" data-end=\"1898\"\u003e• Hydraulic Fluid: Mineral Oil and Compatible Hydraulic Fluids\u003cbr data-start=\"1960\" data-end=\"1963\"\u003e• Application: Industrial Hydraulic Power and Motion Control Systems \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"1cz0398\" data-start=\"2071\" data-end=\"2095\"\u003eCommon Replacements:\u003c\/h3\u003e\n\u003cp data-start=\"2096\" data-end=\"2275\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e• Bosch Rexroth Z1S6P1-3X\/V Sandwich Plate Check Valve\u003cbr data-start=\"2150\" data-end=\"2153\"\u003e• Bosch Rexroth Z1S6P1-4X\/V Check Valve\u003cbr data-start=\"2192\" data-end=\"2195\"\u003e• Yuken MSW-01 Series Sandwich Check Valve\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e","brand":"UCHIDA-REXROTH","offers":[{"title":"New","offer_id":51714352677166,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_af56c250-0baa-43b0-9506-3ffde5fe6585.jpg?v=1770423806","url":"https:\/\/plgautomation.com\/products\/industrial-z1s6p1-31-29-sandwich-type-check-valve","provider":"PLG Automation ","version":"1.0","type":"link"}
