Valve Configuration
Female NPT Inlet
The inlet accepts a compatible male NPT pipe, nipple, fitting, or equipment connection.
Spring-Loaded Check Mechanism
The internal poppet opens under forward flow and closes automatically when flow slows, stops, or reverses.
Female NPT Outlet
The outlet provides a second female threaded connection for straightforward in-line installation.
Construction Details
The Midland in-line check valve uses a durable brass body designed for corrosion resistance and dependable service in compatible plumbing and industrial applications.
An internal spring-loaded poppet responds automatically to system flow conditions, opening with forward pressure and closing when reverse flow begins.
The Viton sealing element provides enhanced resistance to elevated temperatures and a broad range of compatible chemicals compared with many general-purpose elastomers.
Why Choose a Viton Seal?
Chemical Resistance
- Suitable for many compatible oils and fuels
- Good resistance to many chemicals
- Useful in demanding industrial service
- Provides durable sealing performance
- Verify compatibility with the specific media before use
Temperature Capability
- Designed for more demanding temperature conditions
- Offers broader service capability than many general-purpose elastomers
- Suitable for compatible heated fluid applications
- Helps maintain sealing performance under demanding conditions
- Always follow manufacturer temperature limits
How the Check Valve Works
Forward Flow
Forward system pressure pushes the spring-loaded poppet away from its seat, allowing compatible media to flow through the valve.
Reverse Flow
When forward pressure drops or reverses, the spring pushes the poppet toward the seat to help prevent backflow through the piping system.
Typical Applications
Plumbing & Utility Systems
- Water piping
- Pump discharge lines
- Equipment isolation
- Compressed air systems
- Utility fluid piping
Industrial Systems
- Oil service where compatible
- Process fluid systems
- Plant utility piping
- Compressor systems
- Equipment backflow protection
Viton vs. NBR Seal
Viton
Viton is typically selected where improved chemical resistance and higher temperature capability are required for compatible fluids.
NBR
NBR is commonly used for general-purpose water, air, and oil service and may be preferred where those operating conditions and media are appropriate.
Our valve, fitting, and industrial product specialists can help review your valve size, FIP connection requirements, pressure rating, handle configuration, media compatibility, and application before you order.

What type of valve is this?
This is a spring-loaded in-line check valve designed to allow flow in one direction and help prevent reverse flow.
What material is the valve body made from?
The supplied product information identifies a durable brass body.
What seal material is used?
This listing uses a Viton seal.
What type of connections does the valve use?
The valve uses female NPT threaded connections on both ends.
What sizes are available?
The supplied product information identifies sizes from 1/4" through 4".
Does the valve require a handle or actuator?
No. The valve operates automatically using system flow and the internal spring-loaded poppet mechanism.
What is the benefit of a Viton seal?
Viton provides improved resistance to many chemicals and elevated temperatures compared with many general-purpose sealing materials.
Can the valve be used with oil?
The supplied product information identifies oil as a typical compatible service, but final suitability depends on the specific oil, temperature, pressure, and seal compatibility.
How should the valve be installed?
Install the valve with the flow arrow on the body pointing in the intended direction of normal system flow.
What should I verify before ordering?
Confirm nominal size, NPT thread compatibility, operating pressure, temperature, media compatibility, required seal material, and installation orientation before ordering.
Important Ordering & Installation Notes
- This listing is for a Midland Italian Brass In-Line Check Valve with Viton Seal.
- The supplied product information identifies sizes from 1/4" through 4".
- Connections are Female NPT x Female NPT.
- Confirm the required nominal valve size before ordering.
- Verify NPT thread compatibility with the intended piping components.
- Confirm Viton compatibility with the specific system media.
- Verify operating pressure and temperature requirements before installation.
- Install with the body flow arrow pointing in the normal direction of system flow.
- Use an appropriate thread sealant or PTFE tape where permitted by the application.
- Avoid excessive installation torque that could damage the brass body or threaded connections.
- Support connected piping to avoid placing unnecessary mechanical load on the valve.
- Do not install backward, as reverse orientation will prevent proper check valve operation.
- Inspect system performance periodically to ensure the valve is opening and closing properly.
- Install according to applicable piping standards, project requirements, and manufacturer recommendations.
