Shanghai Zhibang Valve Manufacture Co., Ltd is a professional manufacturer established in 2016, specializing in high-quality industrial valves. Our Marine Check Valve PN100 features a full bore design and flanged ends, crafted from durable forged steel. With an annual export value of US$1–1.5 million and ISO9001 certification, we deliver reliable products for global marine applications. This valve is engineered to provide exceptional sealing performance, minimal pressure drop, and long service life in demanding offshore environments.
The Marine Check Valve PN100 is designed to prevent backflow in piping systems operating at high pressures up to 100 bar. Its full bore design means the internal diameter matches the pipe, allowing unrestricted flow and reducing energy losses. The flanged connections ensure easy installation and maintenance, while the forged steel body offers superior strength and corrosion resistance. Available in sizes from DN15 to DN80, this valve is ideal for marine, shipbuilding, and offshore oil & gas systems.
Key Features & Benefits
- Full Bore Design – eliminates flow restrictions, reduces pressure drop and turbulence, improving system efficiency.
- Forged Steel Construction – provides high mechanical strength, excellent toughness, and good resistance to shock and vibration.
- Pressure Rating PN100 – suitable for high-pressure marine systems up to 100 bar (1450 psi).
- Flanged Ends – comply with ANSI, DIN, JIS or other standards (customizable), ensuring leak-proof sealing and easy installation.
- Marine Grade Materials – available in carbon steel (A105), stainless steel (F304/F316) with optional protective coatings for seawater resistance.
- Versatile Disc Options – swing or lift check designs to meet different flow and installation requirements (optional).
- ISO9001 Quality System – each valve is tested and inspected to ensure reliable performance.
