Valve Configuration
Spring-Loaded Poppet
The internal poppet opens with sufficient forward pressure and closes automatically when flow decreases or reverses.
Y-Pattern Body
The angled body configuration provides a compact flow path while allowing convenient access to internal components for service.
Female NPT Ends
Female NPT threaded connections provide straightforward installation into compatible threaded piping systems.
Construction Details
The 316 stainless steel body provides excellent corrosion resistance and durability for compatible industrial and process environments.
The spring-loaded internal mechanism closes quickly as forward flow decreases, helping minimize reverse flow and reduce system shock.
The Y-pattern body provides access to the internal check assembly while maintaining a compact configuration for installation in space-conscious piping layouts.
How the Y-Spring Check Valve Works
Forward Flow
Forward system pressure moves the spring-loaded poppet away from the seat, allowing media to pass through the valve.
Flow Stops or Reverses
As forward pressure falls, the spring drives the poppet back toward the seat to help stop reverse flow through the line.
Why Choose a Y-Spring Check Valve?

- Spring-assisted operation
- Fast closing response
- Helps reduce reverse flow
- Helps limit valve slam
- Automatic operation
Installation Flexibility
- Horizontal installation
- Vertical installation with upward flow
- Compact threaded body

Y-Spring Check vs. Swing Check Valve
Y-Spring Check Valve
A Y-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 flow and typically relies more on gravity and reverse-flow forces to return to the seat.
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 type of valve is this?
This is a Y-pattern spring check valve with a spring-loaded internal poppet.
Does the valve operate automatically?
Yes. The check mechanism responds automatically to changes in system flow and pressure.
What type of connections does it use?
The valve uses female NPT threaded connections.
Can it be installed vertically?
Yes. The supplied product information allows vertical installation when flow travels upward.
Can it be installed horizontally?
Yes. Horizontal installation is also identified as suitable.
What does the spring do?
The spring helps return the poppet to the seat quickly as forward flow decreases, helping prevent reverse flow.
What media can this valve be used with?
The supplied information identifies water, air, oil, steam, and other compatible media, subject to pressure, temperature, and material limitations.
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, NPT thread compatibility, installation orientation, pressure and temperature requirements, and media compatibility.
Important Ordering & Installation Notes
- This listing is for Midland 316 Stainless Steel Y-Spring 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.
- Horizontal installation is permitted according to the supplied product information.
- For vertical installation, flow should travel upward.
- 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.
- Avoid excessive installation torque that could damage the valve 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, depressurize, and drain the system before servicing the valve.
- Do not exceed manufacturer pressure, temperature, or media limitations.
- Follow applicable piping standards and manufacturer recommendations.
