Shanghai Zhibang Valve Manufacture Co., Ltd. has been committed to delivering high-performance fluid control solutions since 2016. Our CB/M1079-81 Marine Pressure Reducing Valve is engineered to meet the demanding requirements of marine and industrial applications. Featuring a durable cast steel body, flanged connections, and adjustable outlet pressure, this valve ensures precise pressure regulation across a wide range of operating conditions. With an annual export value of US$1-1.5 million and ISO9001 certification, we provide reliable products backed by global market experience.
This pressure reducing valve is designed to reduce and stabilize inlet pressure to a preset downstream value, maintaining consistent flow regardless of upstream fluctuations. The cast steel construction offers excellent strength and corrosion resistance, making it suitable for seawater, oil, gas, and steam systems. The flanged connection allows easy installation and maintenance, while the adjustable outlet pressure gives operators flexibility to meet specific system requirements.
Key Features & Benefits
- Durable Cast Steel Body: Withstands high pressure and harsh marine environments, extending service life.
- Adjustable Outlet Pressure: Easily set the desired downstream pressure via a simple adjustment mechanism.
- Flanged Connection (DN15-DN100): Compatible with standard piping systems for quick installation and leak-proof sealing.
- Wide Pressure Range (PN1.6-6.4MPa): Suitable for low to medium pressure applications commonly found in marine and industrial systems.
- Precision Pressure Regulation: Maintains stable outlet pressure even with fluctuating inlet pressure, protecting downstream equipment.
- Versatile Applications: Used in shipbuilding, offshore platforms, water treatment, chemical processing, and more.
- ISO9001 Quality Management: Our manufacturing facilities are ISO9001 certified, ensuring consistent product quality.

Frequently Asked Questions (FAQ)
-
What is the outlet pressure adjustment range?
The standard outlet pressure is adjustable from 0.1 to 4.0MPa, depending on the inlet pressure. Custom ranges are available upon request. -
Can this valve be used for steam applications?
Yes, the cast steel body and appropriate seat materials allow operation with steam within the temperature range of -20°C to +350°C. -
What flanged standards are available?
We offer flanges according to GB, DIN, ANSI, JIS standards. Please specify your requirement when ordering. -
Is the valve suitable for seawater?
The cast steel body with proper coating can handle seawater. For prolonged exposure, we recommend optional stainless steel trim or epoxy coating. -
How do I install the valve correctly?
Ensure the arrow on the body matches the flow direction. Install the valve in a horizontal line with the handle accessible. Avoid overtightening bolts. -
Do you provide certificates for material or pressure test?
Yes, we can provide material certificates, hydrostatic test reports, and ISO9001 certification documents upon request. -
What is the lead time for this valve?
