Shanghai Zhibang Valve Manufacture Co., Ltd., established in 2016, is a professional manufacturer specializing in high-quality industrial valves. Our Marine High Pressure Check Valve PN100 is designed to meet the rigorous demands of marine and offshore applications. With a forged steel body and flanged connection, this valve offers superior strength, leak-proof performance, and long service life under extreme pressure conditions. Backed by our ISO9001 quality management system and a 1-year warranty, it is a reliable choice for shipbuilding, seawater systems, and hydraulic circuits.
The valve is engineered to prevent reverse flow in pipelines where high pressure and corrosive environments are present. The forged steel construction provides excellent mechanical properties, while the flanged design allows for easy installation and maintenance. Whether you are building a new vessel or retrofitting existing systems, this check valve ensures system safety and operational efficiency.
Key Features & Benefits:
- High Pressure Rating PN100: Capable of handling up to 100 bar (1450 psi), suitable for demanding hydraulic and steam systems.
- Forged Steel Body: Offers higher strength and impact resistance compared to cast steel, reducing the risk of body cracking under pressure surges.
- Flanged Connection: Conforms to ANSI B16.5 or DIN EN 1092-1 (optional), ensuring tight sealing and easy alignment with piping systems.
- Corrosion Resistance: Interior surfaces can be coated with epoxy or stainless steel overlay to withstand seawater and acidic media.
- Low Pressure Drop: Streamlined flow path minimizes turbulence and energy loss, improving system efficiency.
- Quick Closing Action: Disc or ball mechanism closes rapidly to prevent water hammer and backflow damage.
- 1-Year Warranty: Covers material and workmanship defects, giving you peace of mind.
- Customizable Options: Available in different disc types (swing, lift, ball), seat materials (PTFE, metal, NBR), and trim configurations to match specific media.

Frequently Asked Questions (FAQ):
Q1: What media can this check valve handle?
A: It is suitable for water, seawater, oil, gas, steam, and many non-corrosive to mildly corrosive fluids. For aggressive chemicals, we recommend stainless steel trim or lining.
Q2: Can the valve be installed vertically?
A: Yes, depending on the disc design. Swing check valves are typically installed horizontally, but lift check valves can work vertically. Our technical team can confirm the best orientation for your system.
Q3: What is the difference between a swing and a lift check valve?
A: Swing check uses a hinged disc that swings open with forward flow; lift check uses a disc that lifts perpendicular to the seat. Both are available, and we can recommend based on your flow rate and pressure conditions.
Q4: Do you provide certificates for material and testing?
A: Yes, we can provide material certificates (MTC), hydrostatic test reports, and dimensional inspection reports upon request.
Q5: How long does shipping take?
A: Typical production time is 15-30 working days. After production, shipping to major ports takes 7-30 days depending on the destination and shipping method.
Q6: Can I customize the end connections, such as wafer type?
A: Yes, while the standard is flanged, we also offer wafer, threaded, or butt-weld ends. Please consult with our sales team for custom requirements.
Q7: Is the valve suitable for fire-safe applications?
A: This model is designed to meet API 6D fire-safe requirements when specified with appropriate construction and materials. Please confirm your specification to ensure compliance.
Q8: What is the warranty coverage?
A: We offer a 1-year warranty covering manufacturing defects. It does not cover damage due to misuse, improper installation, or normal wear. Extended warranty is available upon negotiation.
