Description
Midland 304 Stainless Steel Barrel Spring Check Valve
Midland 304 Stainless Steel Barrel Spring Check Valves are compact in-line valves designed to automatically prevent reverse flow in compatible liquid and gas piping systems.
The spring-loaded internal poppet responds quickly when forward flow stops or reverses, helping protect pumps, compressors, valves, and other system components. Their compact barrel-style configuration makes them especially useful where installation space is limited.

Valve Configuration
Spring-Loaded Poppet
The internal poppet opens with sufficient forward pressure and closes automatically as flow decreases or reverses.
Barrel-Style Body
The compact in-line body helps conserve installation space while providing dependable one-way flow control.
Female Threaded Ends
Female threaded connections provide straightforward installation into compatible piping systems.
Construction Details
The valve body is manufactured from durable 304 stainless steel for corrosion resistance and long service life in compatible piping environments.
The spring-loaded internal poppet responds automatically to changes in system flow, helping minimize reverse flow when forward pressure drops.
The compact barrel-style configuration allows installation in confined piping layouts while maintaining convenient threaded connections on both ends.
How the Spring Check Valve Works
Forward Flow
When inlet pressure exceeds the valve's cracking pressure, the spring-loaded poppet moves away from the seat and allows media to flow through the valve.
Flow Stops or Reverses
As forward pressure decreases, the spring pushes the poppet back toward the seat to help prevent reverse flow through the piping system.
Why Choose a Spring Check Valve?
Responsive Closing
- Spring-assisted closing action
- Responds as forward flow decreases
- Helps minimize reverse flow
- May help reduce valve slam
- Automatic operation
Flexible Installation
- Compact in-line profile
- Suitable for confined spaces
- Can be used horizontally or vertically when appropriate
- Female threaded connections
- No external operator required
304 Stainless Steel Construction
Corrosion Resistance
304 stainless steel provides dependable general-purpose corrosion resistance in many compatible water, air, and industrial fluid applications.
Durable Service
The stainless steel body is designed for repeated service in commercial and industrial systems when properly matched to the media and operating conditions.
Typical Applications
Commercial & Industrial
- Industrial fluid systems
- Commercial mechanical piping
- Pump discharge lines
- Equipment protection
- General plant service
Fluid Handling Systems
- Water systems
- Air systems
- Compatible liquid service
- Compatible gas service
- Process support piping
Spring Check vs. Swing Check Valve
Spring Check Valve
A spring check valve uses a spring-loaded poppet that actively moves toward the seat as flow decreases, allowing responsive closing and flexible installation orientation.
Swing Check Valve
A swing check valve uses a hinged disc that opens with forward flow and relies more heavily on gravity and reverse-flow forces for closing.
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 material is this valve made from?
The supplied product information identifies 304 stainless steel construction.
What type of check valve is this?
This is a barrel-style in-line spring check valve with a spring-loaded internal poppet.
Does the valve operate automatically?
Yes. The spring-loaded mechanism opens with sufficient forward pressure and closes automatically when flow stops or reverses.
What type of connections does it use?
The valve uses female threaded pipe connections.
Can it be installed vertically?
The supplied product information identifies horizontal or vertical installation as suitable when the intended flow direction and manufacturer requirements are followed.
What does cracking pressure mean?
Cracking pressure is the minimum inlet pressure required to begin opening the spring-loaded check mechanism.
What equipment can this valve help protect?
It can help protect pumps, compressors, piping, valves, and other equipment from reverse flow.
Does installation direction matter?
Yes. Install the valve with the flow arrow pointing in the intended direction of normal system flow.
What should I verify before ordering?
Confirm valve size, thread compatibility, cracking pressure requirements, operating pressure, temperature, media compatibility, and installation orientation.
Important Ordering & Installation Notes
- This listing is for Midland 304 Stainless Steel Barrel Spring Check Valves.
- Confirm the required valve size before ordering.
- Verify female thread compatibility with the intended piping system.
- Confirm the required cracking pressure for the application.
- Install with the flow arrow pointing in the intended direction of system flow.
- Verify that the selected horizontal or vertical installation orientation is permitted.
- Confirm 304 stainless steel compatibility with the intended media.
- Verify system pressure and operating temperature requirements.
- Use an appropriate thread sealant where permitted.
- Avoid excessive installation torque that could damage the valve body or threaded connections.
- Support connected piping to avoid excessive mechanical load on the valve.
- Check valve operation after installation to confirm proper forward flow and reverse-flow closure.
- Fully isolate and depressurize the system before performing maintenance.
- Do not exceed manufacturer pressure, temperature, or media limitations.
- Follow applicable piping standards and manufacturer recommendations.
