Founded in 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. has been dedicated to delivering high-performance fluid control solutions for the global marine industry. Our DN15-DN50 Marine High Pressure Reducing Valve PN64, Forged Steel, Flanged, DNV LR Approved represents a perfect blend of robust engineering and reliable pressure regulation, designed to withstand the demanding conditions of shipboard systems. With an annual export value exceeding US$1 million, we serve markets across North America, Europe, Asia, and beyond, ensuring that every valve meets stringent quality standards.
This pressure reducing valve is specifically engineered for high-pressure marine applications, capable of reducing inlet pressures up to 64 bar (PN64) to a stable, lower outlet pressure. The forged steel body offers exceptional strength and corrosion resistance, while the flanged connections facilitate easy installation and maintenance. Backed by ISO9001 certification and approved by DNV and LR classification societies, this valve is a trusted choice for shipbuilders and marine engineers worldwide.
Key Features & Technical Specifications
- Forged Steel Construction: High-strength carbon steel or alloy steel forging ensures durability and resistance to high pressure and temperature fluctuations.
- Pressure Reduction Capacity: Inlet up to 64 bar (PN64); outlet pressure adjustable within a wide range, typically 1-40 bar depending on spring selection.
- Flanged Connections: Standard flanges per DIN, ANSI, or JIS (customizable upon request) for secure piping integration.
- DNV & LR Type Approval: Certified by Det Norske Veritas (DNV) and Lloyd’s Register (LR) for marine applications, ensuring compliance with international maritime safety standards.
- Size Range: DN15 to DN50 (1/2" to 2") – versatile for various branch lines and service points.
- Self-Actuating Design: No external power required; uses diaphragm or piston sensing to maintain accurate downstream pressure.
- Low Maintenance: Seat and internal components are replaceable, extending service life and reducing downtime.
- Testing & Quality Assurance: 100% hydrostatic tested at 1.5x rated pressure and seat leakage tested per ISO 5208.

Frequently Asked Questions
-
Q: What is the maximum inlet pressure this valve can handle?
A: The valve is rated for PN64, meaning a maximum inlet pressure of 64 bar (928 psi). However, it is recommended to operate within 80% of the rated pressure for long-term reliability. -
Q: Can I adjust the outlet pressure?
A: Yes, the outlet pressure is adjustable by changing the internal spring. Standard spring ranges cover 1-40 bar; custom ranges are available upon request. -
Q: Are these valves suitable for seawater applications?
A: While the forged steel body is corrosion-resistant, for direct seawater contact we recommend selecting appropriate seal materials (e.g., Viton) and optional coatings. Please consult our technical team for specific requirements. -
Q: What certifications does the valve have?
A: The valve is manufactured under ISO9001 quality management system and holds type approval from DNV and LR for marine use. Other certifications (e.g., CCS, ABS) can be applied for as needed. -
Q: What is the delivery time?
A: Standard sizes (DN15-DN50) typically have a lead time of 15-30 days, depending on quantity and customization. Express delivery can be arranged for urgent orders. -
Q: Do you provide installation instructions or technical support?
A: Yes, we offer a full technical manual with each valve, and our engineers are available for remote support or on-site commissioning upon request. -
Q: Can I get a sample before bulk order?
A: Yes, we provide sample valves for evaluation. The sample cost and shipping are negotiable, and we can deduct the sample cost from the first bulk order. -
Q: What is the warranty period?
A: We offer a standard 12-month warranty from the date of shipment against manufacturing defects. Extended warranty options are available.
