Shanghai Zhibang Valve Manufacture Co., Ltd. has been a trusted manufacturer of high-performance marine valves since 2016. Our Marine Bronze Pressure Reducing Valve (DN15-DN50, PN1.0-2.5MPa) is specifically engineered for demanding seawater applications. Crafted from premium bronze and backed by CCS certification, this valve delivers precise pressure control, exceptional corrosion resistance, and long-term reliability in harsh marine environments. Whether you need a threaded or flanged connection, our valve is the optimal choice for shipbuilding, offshore platforms, and coastal installations.

Key Features & Technical Specifications

Material Excellence: Made from high-strength marine-grade bronze (C95800 / C95500) – superior resistance to seawater corrosion, dezincification, and pitting.
Pressure Range: Rated for PN1.0 to PN2.5MPa (150–360 psi), covering most low-to-medium pressure marine systems.
Size Options: Available in DN15, DN20, DN25, DN32, DN40, DN50 – suitable for pipes from 1/2" to 2".
Connection Types: Both threaded (BSP/NPT) and flanged (EN1092 / ANSI B16.5) configurations are offered to match your existing piping layout.
Pressure Reduction Accuracy: Factory-set or adjustable outlet pressure from 0.1 to 1.6MPa, with minimal pressure drop fluctuation.
Seawater Compatibility: Dedicated internal coating and seal materials (e.g., EPDM, PTFE) prevent galvanic corrosion and biofouling.
Easy Maintenance: Modular design allows quick replacement of diaphragm, seat, and spring without removing the valve from the pipeline.
Certifications: CCS (China Classification Society) type-approved; ISO9001:2015 quality management system certified.

Customer Benefits & Application Advantages

Extended Service Life: Bronze construction resists saltwater corrosion 3–5 times longer than standard brass or cast iron, reducing replacement frequency and downtime.
Precise Pressure Control: Stabilizes downstream pressure within ±5% of set point, protecting sensitive equipment (pumps, heat exchangers, instrumentation) from overpressure damage.
Versatile Installation: Threaded models for quick retrofitting on existing threaded pipes; flanged models for high-pressure/high-flow systems with bolted joints.
Low Maintenance Costs: Self-cleaning internal design minimizes sediment accumulation; seats and seals can be replaced in minutes without special tools.
Global Compliance: CCS certification ensures acceptance by major ship classification societies; also meets ISO9001 quality standards.
Ideal for shipboard fire‑fighting systems, ballast water treatment, deck washdown, cooling circuits, and offshore desalination units.

Frequently Asked Questions (FAQ)

Q: Is this valve suitable for all seawater applications?
A: Yes – the bronze body and specialized elastomers (EPDM/PTFE) are specifically selected for seawater resistance. It can also be used for fresh water, cooling water, and light oil. For aggressive chemical media, please consult our engineers for customization.
Q: Can I get the valve with a preset outlet pressure?
A: Absolutely. We can factory-set the outlet pressure anywhere between 0.1 – 1.6 MPa as per your requirement. If you prefer adjustable, all models come with an adjustment screw and pressure gauge port.
Q: What connection types are available for DN15-DN50?
A: Both threaded and flanged connections are offered. Threaded options include BSPP (British Standard) and NPT (American Standard). Flanged models comply with EN1092 (PN16/PN25) and ANSI B16.5 Class 150/300. Please specify when ordering.
Q: Is CCS certification standard for all sizes?
A: Yes, every valve from DN15 to DN50 in both threaded and flanged series is CCS type-approved. We also provide a copy of the certificate upon request.
Q: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 10 pieces per size, but we can accept smaller trial orders for sample evaluation. For large quantity projects, we offer competitive pricing and reduced lead time.
Q: How long is the delivery time?
A: For standard sizes (DN15-DN50, threaded or flanged), delivery is 15–25 working days after order confirmation. Custom color or special pressure settings may require 25–35 days.
Q: Do you provide after-sales support?
A: Yes – we offer a 12-month warranty against manufacturing defects. Our technical team is available via email, phone, or WhatsApp to assist with installation, troubleshooting, and spare parts replacement.
Q: Can I get a sample before placing a bulk order?
A: Certainly. Sample orders are welcome. We charge a nominal sample fee (refundable upon bulk order) and we ship via express (DHL, FedEx, UPS) within 5 days.
