Pressure Reducing Valve
We are Shanghai Zhibang Valve Manufacture Co., Ltd, a professional manufacturer established in 2016 with an annual export value of US$1 million to US$1.5 million. Our DIN Marine Pressure Reducing Valve for Seawater Cooling Lines is engineered to deliver precise pressure control in demanding marine environments. Crafted from high-grade cast bronze and featuring an anti-galvanic design, this valve reliably reduces inlet pressure to a stable 0.5–4 bar outlet range, protecting downstream equipment from pressure surges. Its flanged DN25 body meets PN16 rating and strict DIN standards, making it an ideal choice for shipbuilding, offshore platforms, and coastal cooling systems.
Key Features & Technical Specifications
- Durable Cast Bronze Construction – Resistant to seawater corrosion, biofouling, and galvanic attack, ensuring long service life in saltwater environments.
- Anti-Galvanic Protection – Special material selection and design minimize electrochemical corrosion when connected to dissimilar metals in piping systems.
- Precise Pressure Regulation – Adjustable outlet pressure from 0.5 to 4 bar with high accuracy, suitable for a wide range of cooling line requirements.
- DIN Standard Compliance – Manufactured according to DIN EN standards, guaranteeing interchangeability and compatibility with European marine systems.
- Flanged Connection – DN25, PN16 – Easy to install and maintain, with robust flanges designed for high-pressure seawater applications.
- Compact & Lightweight – Streamlined body reduces space occupation and simplifies handling during installation.
- Low Maintenance – Self-cleaning internal mechanism and replaceable seat reduce downtime and operational costs.

Frequently Asked Questions (FAQ)
- Q: Can this valve be used in freshwater or other liquids? A: Yes, it is suitable for seawater, brackish water, freshwater, and other non-aggressive fluids within the temperature and pressure limits.
- Q: What is the adjustment method for outlet pressure? A: The valve features an adjustable spring-loaded diaphragm. Simply turn the adjusting screw (or optional handwheel) to set the desired outlet pressure between 0.5 and 4 bar.
- Q: Does the anti-galvanic feature require any special maintenance? A: The built-in sacrificial anode is designed to be replaced periodically. We recommend inspecting the anode every 6–12 months depending on water salinity and operating conditions.
- Q: Is the valve supplied with flanges or gaskets? A: Flanges are integrated into the valve body. Gaskets and bolts are not included by default but can be provided as optional accessories.
- Q: Can I get a different outlet pressure range, e.g., 1–6 bar? A: The standard range is 0.5–4 bar. Custom ranges are available upon request – please contact our sales team with your requirements.
- Q: What is the typical lead time? A: For standard models, lead time is 15–25 working days. Custom orders may take longer depending on specification complexity.
- Q: Do you provide certificates of material and pressure test? A: Yes, we can issue material certificates (EN 10204 3.1) and hydrostatic test reports upon request.
- Q: How do I know this valve fits my existing DIN flanges? A: Our valve conforms to DIN EN 1092-2 PN16 flange dimensions. Please verify flange bolt circle diameter and number of holes – we can provide a dimensional drawing upon request.
