Commonly installed in industrial machinery, fluid handling equipment, hydraulic power units, and process control systems. Maintenance technicians use this valve to protect pumps, compressors, and other equipment from damage caused by backflow.

It is commonly used in hydraulic systems, pneumatic systems, process piping, pumps, compressors, and fluid transfer equipment. The valve automatically opens when flow is present in the intended direction and closes when reverse flow occurs. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5hg6bl\" data-start=\"1061\" data-end=\"1090\"\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cp data-start=\"1092\" data-end=\"1850\"\u003e• Manufacturer Part Number (MPN): 55-319931\u003cbr data-start=\"1135\" data-end=\"1138\"\u003e• Alternate Part Number: 55319931\u003cbr data-start=\"1171\" data-end=\"1174\"\u003e• Product Type: Check Valve\u003cbr data-start=\"1201\" data-end=\"1204\"\u003e• Function: One-Way Flow Control\u003cbr data-start=\"1236\" data-end=\"1239\"\u003e• Application: Hydraulic, Pneumatic, and Process Fluid Systems\u003cbr data-start=\"1301\" data-end=\"1304\"\u003e• Valve Type: Automatic Check Valve\u003cbr data-start=\"1339\" data-end=\"1342\"\u003e• Flow Direction: Unidirectional\u003cbr data-start=\"1374\" data-end=\"1377\"\u003e• Operation: Prevents Reverse Flow\u003cbr data-start=\"1411\" data-end=\"1414\" data-is-only-node=\"\"\u003e• Mounting Type: Inline Installation\u003cbr data-start=\"1450\" data-end=\"1453\"\u003e• Compatible Media: Hydraulic Oil, Air, Water, and Process Fluids (application dependent)\u003cbr data-start=\"1542\" data-end=\"1545\"\u003e• Construction: Industrial Metal Valve Body\u003cbr data-start=\"1588\" data-end=\"1591\"\u003e• Industry Applications: Manufacturing, Fluid Handling, Process Control, Automation\u003cbr data-start=\"1674\" data-end=\"1677\"\u003e• Operating Environment: Industrial Systems\u003cbr data-start=\"1720\" data-end=\"1723\"\u003e• Service Use: Replacement Flow Control Component\u003cbr data-start=\"1772\" data-end=\"1775\"\u003e• Weight: Approximately 22 lb (10 kg) \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"1cz0398\" data-start=\"1852\" data-end=\"1876\"\u003eCommon Replacements:\u003c\/h3\u003e\n\u003cp data-start=\"1878\" data-end=\"1975\"\u003e• OEM 55-319931 Check Valve\u003cbr data-start=\"1905\" data-end=\"1908\"\u003e• Industrial Inline Check Valve\u003cbr data-start=\"1939\" data-end=\"1942\"\u003e• One-Way Hydraulic Check Valve\u003c\/p\u003e","brand":"PLG Automation ","offers":[{"title":"New","offer_id":51727550611758,"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_b8b981a9-0e4e-4b18-ba3d-5b9b5ae40d26.jpg?v=1770583253","url":"https:\/\/plgautomation.com\/products\/industrial-55-319931-check-valve","provider":"PLG Automation ","version":"1.0","type":"link"}
