Description
Midland 316 Stainless Steel Spring Check Valve (M x F)
Midland 316 Stainless Steel Spring Check Valves are designed to allow flow in one direction while automatically preventing reverse flow in compatible plumbing, industrial, and fluid handling systems.
Featuring a male NPT inlet and female NPT outlet, these compact inline check valves use a spring-loaded internal poppet for fast, dependable closing when forward flow stops or reverses. Corrosion-resistant 316 stainless steel construction provides durability for demanding service environments.

Valve Configuration
Male NPT Inlet
The male threaded inlet connects directly to a compatible female NPT piping or fitting connection.
Female NPT Outlet
The female threaded outlet accepts a compatible male NPT connection for straightforward inline installation.
Spring-Loaded Poppet
The internal spring-loaded poppet responds automatically to flow conditions and closes when forward flow stops or reverses.
Construction Details
The valve body is precision machined from corrosion-resistant 316 stainless steel for dependable strength and long service life in compatible applications.
The internal spring-loaded poppet provides responsive opening and closing while helping maintain positive reverse-flow protection.
The compact inline design allows installation in piping layouts where space is limited while maintaining convenient male-to-female threaded connections.
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 toward the seat to help prevent reverse flow through the piping system.
Why Choose an M x F Spring Check Valve?
Convenient Inline Transition
- Male inlet connection
- Female outlet connection
- Can reduce the need for additional adapters
- Compact installation footprint
- Useful for equipment and piping connections
Automatic Protection
- No manual operator required
- Responds automatically to flow changes
- Helps protect pumps and equipment
- Prevents unwanted reverse flow
- Spring-assisted closing action
316 Stainless Steel Construction
Corrosion Resistance
316 stainless steel provides excellent corrosion resistance for many compatible water, air, oil, chemical, and process applications.
Industrial Durability
The stainless steel body is designed for dependable service when properly matched to system pressure, temperature, and media.
Typical Applications
Commercial & Industrial
- Industrial utility piping
- Commercial mechanical systems
- Pump discharge lines
- Equipment protection
- Process support piping
Fluid Handling
- Water systems
- Air systems
- Oil systems
- Compatible chemical service
- General process media
Spring Check vs. Swing Check Valve
Spring Check Valve
A spring check valve uses a spring-loaded poppet for responsive closing and can support multiple installation orientations when used as specified.
Swing Check Valve
A swing check valve uses a hinged disc that opens with forward flow and generally depends more on gravity and reverse-flow forces to close.
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 316 stainless steel construction.
What connection configuration does it use?
The valve uses a male NPT inlet and female NPT outlet.
Does the valve operate automatically?
Yes. The spring-loaded check mechanism opens with sufficient forward pressure and closes automatically when flow stops or reverses.
Can it be installed vertically?
Yes. For vertical installation, the supplied product information specifies upward flow.
Can it be installed horizontally?
Yes. Horizontal installation is also identified as suitable.
What does low cracking pressure mean?
Cracking pressure is the minimum inlet pressure required to begin opening the spring-loaded poppet. A low cracking pressure allows the valve to respond to relatively small forward pressure.
What is the valve used for?
It is designed to provide automatic one-way flow control and prevent reverse flow in compatible piping systems.
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, male and female NPT thread compatibility, cracking pressure requirements, installation orientation, operating pressure, temperature, and media compatibility.
Important Ordering & Installation Notes
- This listing is for Midland 316 Stainless Steel Spring Check Valves with M x F connections.
- Confirm the required nominal valve size before ordering.
- Inlet connection is male NPT.
- Outlet connection is female NPT.
- Install with the flow arrow pointing in the intended direction of system flow.
- Horizontal installation is permitted according to the supplied product information.
- For vertical installation, flow should travel upward.
- Confirm the required cracking pressure for the application.
- Verify 316 stainless steel compatibility with the intended media.
- Confirm system pressure and operating temperature requirements.
- Use appropriate thread sealant on NPT connections where permitted.
- Avoid excessive installation torque that could damage the valve or threads.
- 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.
- Follow applicable piping standards and manufacturer recommendations.
