As part of the SHR family, SHR-012 is the double-acting variant that uses pilot pressure applied through ports A or B to open the opposite flow path between A and B, with an area ratio of 3.3:1. It conforms to ISO 4401 mounting patterns for 06-size interfaces, enabling straightforward integration into standard hydraulic manifolds. The valve is intended for use with hydraulic mineral oil or synthetic fluids with similar lubricating characteristics, and seal materials can be configured in NBR, FKM, or HNBR depending on the application. Available spring cracking pressures include 0.5 bar (standard), 2 bar, 4 bar, and 8 bar to tailor the pilot actuation, while the direct or pilot-operating configuration supports reliable, one-way flow control in compact installations. Typical applications include hydraulic power units, machine tools, presses, and automated lines where controlled backflow and precise pilot activation are essential.\u003c\/p\u003e\u003c\/div\u003e","brand":"ATOS","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51660341444910,"sku":null,"price":1501.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_96c72374-43ce-4bc9-bef0-89f0bc770148.jpg?v=1769536462","url":"https:\/\/plgautomation.com\/products\/industrial-shr-012-51-check-valve","provider":"PLG Automation ","version":"1.0","type":"link"}
