FLOMAX DCV Disc Check Valve is a spring-type non-slam check valve designed for dependable prevention of reverse flow in industrial pipelines. Manufactured with a single-piece investment-cast stainless-steel body and stainless-steel internal components, it offers good strength, corrosion resistance, and durability. The valve features a full-flow, low-friction design that helps reduce flow resistance and pressure loss during operation. Its spring-assisted disc closes quickly when the flow stops or reverses, helping minimise slamming and pipeline shock. Available in sizes from ½ inch to 8 inches, the compact wafer-type valve is installed between two ANSI B16.5 Class 150 flanges.

It allows the media to flow in one direction and automatically closes when the flow stops or reverses, preventing backflow.
The valve is available in sizes ranging from ½ inch to 8 inches.
Non-slam operation means the spring-loaded disc closes quickly and smoothly before significant reverse flow develops, helping reduce water hammer, noise, and pipeline shock.
It has a compact wafer-type design and is installed between two compatible ANSI B16.5 Class 150 pipeline flanges.
Yes. It is designed for steam and compatible high-pressure services. However, the exact temperature and pressure suitability should be confirmed before installation.
