More info

A Pneumatic One-Way Check Valve is a safety and control component that allows compressed air to flow in one direction while completely blocking it in the reverse direction.

Common Specifications

Medium: Filtered compressed air.
Operating Pressure: Typically 0.5 to 10 Bar (7–145 PSI).
Cracking Pressure: Low (usually <0.05 MPa) to allow easy forward flow.
Material: Usually Nickel-plated brass or Aluminum alloy for corrosion resistance.
Seal: NBR or Viton for airtight performance.

Size & Flow Reference

Port Size	Typical Use Case
1/8"	Small actuators, pilot lines, or compact 100 series setups.
1/4"	Standard industrial cylinders and 200 series valves.
3/8"	High-flow applications and medium-sized air tools.
1/2"	Main supply lines or large-bore heavy-duty cylinders.

Key Functions

Pressure Maintenance: Prevents air from leaking back into the compressor or tank if the power fails.
Circuit Protection: Protects sensitive components from "back-pressure" surges.
Safety: Holds a cylinder in position if an air line ruptures.
