Vertical Threaded Brass Check Valve

This Vertical Brass Check Valve is designed for vertical installations to ensure one-way flow of fluids or gases. Made from high-quality forged brass, it offers excellent resistance to corrosion, high temperatures, and pressure variations. The spring-loaded mechanism ensures quick shut-off to prevent reverse flow.

❓ Frequently Asked Questions (FAQ)

Q1: Can this brass check valve be installed horizontally?

A: This valve is specifically designed for vertical installation with upward flow direction. For horizontal installations, we recommend using a universal inline check valve instead. Always refer to the arrow mark on the body to ensure correct flow direction.

Q2: What fluids is this valve compatible with?

A: The valve is suitable for water, compressed air, and neutral fluids (non-aggressive). For use with chemicals or corrosive media, please contact us to confirm material compatibility or request a PTFE seal upgrade.

Q3: What is the difference between PN16 and PN25?

A: PN16 and PN25 refer to nominal pressure ratings.

PN16: Maximum working pressure 16 bar
PN25: Maximum working pressure 25 bar
Choose PN25 if your system operates under higher pressure conditions.

Q4: What is the minimum opening (cracking) pressure?

A: The valve typically opens at a cracking pressure of approximately 0.2 bar. This allows it to function efficiently in low-pressure systems.
