Questions about this product
- What types of gases or liquids can I run through this check valve?
- This valve is designed specifically for compressed air and inert gases. Do not use it with water, corrosive chemicals, or hazardous liquids. The brass body and elastomeric seals work best in standard pneumatic systems.
- What is the maximum pressure this valve can handle before it fails?
- This pneumatic valve handles a maximum pressure of 150 PSI or 10 Bar. It opens easily with a low cracking pressure between 0.5 and 5 PSI. Avoid using it in high-pressure hydraulic systems.
- How do I know which way to install this valve in my air line?
- Look for the flow direction arrow marked directly on the brass valve body. You can mount it vertically or horizontally because the internal spring assists with closure. Just thread your male BSP fittings into the female ports to secure the connection.
