Product Q&A

Q:What is the working principle of this brass check valve?

It operates on a passive, automatic mechanism. Forward flow pressure pushes the closure element off the seat, allowing flow. Reverse flow causes the spring or gravity to drive the element back onto the seat, forming a tight seal to block backflow instantly.

Q:What materials are used in the construction of the valve?

The valve body, closure element (disc or piston), and seat are primarily made of brass. Spring-loaded types also include a spring. Brass offers excellent corrosion resistance, thermal conductivity, and antimicrobial properties.

Q:What types of media can this valve handle?

It is suitable for Gas, Oil, Water, Chemical, and Steam. It is particularly ideal for water and low-corrosive media applications due to brass's durability against rust and wear.

Q:What are the available connection forms and standards?

The connection form is Thread. It complies with ASME, ANSI, JIS, En, and ISO standards, making it suitable for various international industrial and household usage requirements.

Q:What is the warranty period and certification?

The valve comes with a 2-year warranty. It is certified under ISO9001:2008 and CE standards, ensuring quality and safety for industrial and household applications.
