Shop high-pressure check valves for hydraulic and industrial systems where one-way flow control is required under elevated operating pressures. This collection includes Midland Industries carbon-steel check valves with FNPT and female SAE threaded connections in multiple sizes, flow capacities, and cracking-pressure configurations.
High-Pressure Check Valves for Hydraulic Systems
High-pressure check valves allow fluid to flow in the intended direction while automatically restricting reverse flow. They are commonly used in hydraulic circuits to help maintain directional flow and protect pumps, cylinders, accumulators, lines, and other system components from unwanted backflow.
Models in this collection include working-pressure ratings up to 5,000 PSI, with additional configurations rated for 3,000 PSI service. Always confirm the specific pressure rating of the selected valve against the maximum operating pressure of the hydraulic system.
FNPT and SAE Check Valve Connections
Available connection options include female NPT and female SAE threaded designs across multiple nominal sizes. Carbon-steel construction provides a durable valve body for demanding hydraulic and industrial applications.
Flow capacity and cracking pressure vary by model. These specifications should be considered along with connection size and working pressure when selecting a valve for a specific circuit.
Choosing a High-Pressure Check Valve
Before ordering, verify the maximum system pressure, nominal size, thread type, flow requirement, cracking pressure, body material, and fluid compatibility. Selecting the correct cracking pressure is especially important because it determines the upstream pressure required before the valve begins to open.
