With an annual export value exceeding US$5 million and a strong presence in over 12 major markets, including North America, Europe, and Oceania, we bring reliability and expertise to every product we offer. This check valve is built from premium 316 stainless steel, ensuring exceptional corrosion resistance and long service life in demanding industrial applications.
The CV-3-316 series is engineered to maintain unidirectional flow in pipelines, automatically closing when reverse flow occurs. Its compact design and robust construction make it an ideal choice for water treatment, chemical processing, oil and gas, and many other sectors. Below we highlight the key features, technical specifications, and benefits that set this product apart.
Key Features
Premium Material: Manufactured from 316 stainless steel, offering superior resistance to corrosion, pitting, and chemical attack compared to standard 304 stainless steel.
Reliable Sealing: Equipped with a spring-assisted plunger mechanism that ensures positive shut-off even under low-pressure conditions. Available seal options include PTFE, Viton, or Buna-N to suit various media.
Compact & Durable: The streamlined body design minimizes pressure drop and saves space. Rated for pressures up to 300 psi (20.7 bar) and temperatures from -20°C to 150°C.
Easy Installation: Threaded NPT connections (standard) allow for simple integration into existing piping systems. Optional flanged or welded ends are available upon request.
Low Maintenance: The internal components are easily replaceable, reducing downtime and maintenance costs over the product lifecycle.
Full Port Design: Provides unrestricted flow, minimizing turbulence and pressure loss.
