ISO9001 Quality Management System
Shanghai Zhibang Valve Manufacture Co., Ltd., established in 2016 and backed by ISO9001 certification, specializes in producing high-performance valves for demanding industrial environments. Our Marine Butterfly Valve for Seawater Cooling Systems embodies our commitment to reliability and durability, engineered specifically to withstand the corrosive challenges of seawater while ensuring efficient flow control in marine cooling circuits.
This valve is a critical component for maintaining optimal operating temperatures in ship engines, offshore platforms, and coastal power plants. By integrating a 316L stainless steel disc with an EPDM sealing system and adhering to the GB/T3036 design standard, we deliver a product that offers long service life, minimal maintenance, and dependable performance in harsh saline conditions.
Core Product Features & Technical Specifications:
- Corrosion-Resistant Construction: The disc is manufactured from 316L stainless steel, which provides superior resistance to pitting and crevice corrosion caused by chloride-rich seawater.
- Robust Sealing Solution: The seat utilizes EPDM (Ethylene Propylene Diene Monomer) rubber, known for its excellent resilience against seawater, ozone, and a wide temperature range.
- Standardized Design: The valve is designed according to the GB/T3036 standard, ensuring compatibility with common piping layouts and predictable performance metrics.
- Versatile Operation: Available with a manual handwheel for direct control. For automated systems, the valve can be equipped with pneumatic, hydraulic, or electric actuators upon request.
- Broad Size Availability: We offer a standard range from DN50 to DN600 to suit various pipeline diameters. Custom sizes outside this range are also customizable.
- Leakage Prevention: The design focuses on creating a tight seal when closed, minimizing fluid loss and protecting system integrity.

- Adaptable Control: The option for manual or actuated operation allows integration into both simple and complex automated control systems.
Frequently Asked Questions (FAQ):
-
Q: Why is 316L stainless steel preferred over 304 for seawater applications?
A: 316L contains molybdenum, which significantly enhances its resistance to chloride-induced corrosion, such as pitting and crevice corrosion, common in seawater. 304 stainless steel is less suitable for prolonged exposure to saline environments. -
Q: What makes EPDM a good seal material for this valve?
A: EPDM rubber exhibits excellent resistance to seawater, ozone, weathering, and a broad temperature range. It maintains elasticity and sealing capability in the challenging conditions of marine cooling systems. -
Q: Does the GB/T3036 design standard affect international compatibility?
A: The GB/T3036 standard defines dimensions and performance criteria. Our valves' flanged connections are designed to be compatible with international piping practices, ensuring they can be integrated into global projects. -
Q: Can this valve be used with other corrosive fluids besides seawater?
A: Yes. The combination of 316L and EPDM provides good resistance to many other corrosive media, including certain chemicals and brackish water. Specific fluid compatibility can be confirmed upon request. -
Q: What are the available options for valve actuation?
A: The valve is primarily supplied with a manual handwheel. For remote or automated control, we can provide pneumatic (air), hydraulic, or electric actuators. The choice depends on your system's available power source and control requirements. -
Q: How does the pressure rating (PN10/PN16) relate to my system's requirements?
A: PN10 corresponds to a nominal pressure of 10 bar, and PN16 to 16 bar. You should select the rating that meets or exceeds the maximum operating pressure in your cooling system pipeline to ensure safe operation. -
Q: What is the typical delivery time for standard sizes?
A: For standard sizes within our DN50-DN600 range, we maintain inventory for common sizes, leading to shorter lead times. Exact delivery schedules can be provided based on the specific order and destination port. -
Q: Which ports does Shanghai Zhibang use for shipment?
A: We primarily ship from Shanghai, Guangzhou, Hong Kong, and Beijing ports, offering flexibility for logistics to our main markets across North America, South America, Europe, Asia, Africa, and Oceania.
