This solenoid-piloted, ISO 4401-05 \/ CETOP 5 subplate-mounted unit from the DG4S4 series uses spool code 012A and design series 50, and it carries the alternate part number DG4S4012A50. It is designed for hydraulic oil and is commonly used in hydraulic power units, industrial presses, injection molding machines, machine tools, and automated manufacturing equipment where precise actuator direction and dependable hydraulic operation are required. The valve provides hydraulic flow direction control with reverse flow prevention and is suitable for industrial-duty environments, adding reliable control to manufacturing lines. Common replacements include DG4S4-012C-50 and DG4S4-012A-24DC-50, supporting retrofit in existing lines. In practice, this means improved control over hydraulic cylinder and motor operation in equipment such as presses, tooling machines, and automation systems, where stable actuation and compatibility with standard subplate mounting simplify integration.\u003c\/p\u003e\u003c\/div\u003e","brand":"Vickers","offers":[{"title":"New","offer_id":46248579367146,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-004.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/vickers-dg4s4-012a-50-l4-hydraulic-check-valve","provider":"GTG Hardware","version":"1.0","type":"link"}
