Valve Configuration
Spring-Loaded Check
The internal check mechanism opens with sufficient forward pressure and closes automatically when flow decreases or reverses.
Female NPT Ends
Female threaded connections provide straightforward installation into compatible standard NPT piping systems.
Hex Body
The hex-shaped exterior provides convenient wrench flats for controlled installation and removal using standard tools.
Construction Details
The valve body is precision machined from 316 stainless steel to provide excellent corrosion resistance and dependable service life in compatible demanding environments.
The internal spring-loaded mechanism allows forward flow while automatically returning toward the closed position when flow stops or reverses.
The compact inline configuration minimizes installation space, while the hex body provides practical wrenching surfaces for assembly and maintenance.
How It Works
Forward Flow
When inlet pressure reaches the required opening force, the internal check element moves away from the seat and allows media to pass through the valve.
Reverse Flow
When forward pressure drops or flow reverses, the spring returns the check element toward the seat to help prevent backflow.

What material is this valve made from?
The supplied product information identifies 316 stainless steel construction.
What type of connections does it use?
The valve uses female NPT threaded connections.
How does the check valve operate?
The valve uses an internal spring-loaded mechanism that opens with forward flow and closes automatically when flow stops or reverses.
Does the valve require manual operation?
No. The check mechanism operates automatically according to system flow conditions.
What is the purpose of the hex body?
The hex exterior provides wrench flats that make installation and removal easier using standard tools.
Can this valve be used with liquids and gases?
The supplied product information identifies compatible liquid and gas service, subject to pressure, temperature, and material compatibility requirements.
Does installation direction matter?
Yes. 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 valve size, NPT thread compatibility, operating pressure, temperature, intended media, and installation requirements before ordering.
Important Ordering & Installation Notes
- This listing is for Midland 316 Stainless Steel In-Line Check Valves.
- Confirm the required nominal valve size before ordering.
- Verify female NPT thread compatibility with the intended piping system.
- Install with the flow arrow pointing in the intended direction of system flow.
- Verify 316 stainless steel compatibility with the intended media.
- Confirm system pressure and operating temperature requirements before installation.
- Use an appropriate thread sealant where permitted.
- Use the hex body wrench flats during installation rather than applying force to unsupported sections of the valve.
- Avoid excessive installation torque that could damage the valve or threaded connections.
- Support connected piping to prevent 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 servicing or replacement.
- Do not exceed manufacturer pressure, temperature, or media limitations.
- Follow applicable piping codes and manufacturer recommendations.
