Shop check valves for hydraulic, industrial, pneumatic, water, and fluid-control systems where flow must travel in one direction while reverse flow is restricted. This collection includes check valves from DNP Americas and Midland Industries in multiple pressure ratings, sizes, materials, connection styles, and operating configurations.
Check Valves for One-Way Flow Control
Check valves operate automatically in response to system pressure. Forward pressure opens the valve to allow flow through the system, while reverse pressure moves the valve toward the closed position to help prevent backflow. They are used throughout hydraulic circuits, piping systems, pumps, equipment, and other applications where controlling reverse flow is important.
Shop Check Valves by Type
For piping and fluid-transfer applications, browse our swing check valves, including threaded and flanged configurations in several body materials and sizes.
Our in-line check valves install directly in the flow path and are available in brass, bronze, and stainless-steel configurations with multiple threaded connection styles.
For applications requiring a spring-assisted closing mechanism, shop our spring check valves, including Y-pattern, 1-piece, and barrel-type designs.
For demanding hydraulic systems, browse our high-pressure check valves, including carbon-steel models with FNPT and SAE connections and working-pressure ratings up to 5,000 PSI.
Choosing the Right Check Valve
Start by confirming the maximum system pressure, required flow rate, nominal size, inlet and outlet connection types, body material, seal compatibility, operating temperature, and intended fluid. Depending on the application, cracking pressure may also be an important selection factor because it determines the upstream pressure required before the valve begins to open.
Check Valve Pressure and Connection Requirements
Pressure ratings vary substantially across the collection, from general industrial fluid-control valves to check valves designed for high-pressure hydraulic service. Connection options include NPT, SAE, FPT, FNPT, flanged, and other configurations depending on the valve design.
