Certification ISO9001 Quality Management System

As a specialized manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. is dedicated to producing high-performance fluid control solutions for demanding marine environments. Our Marine OEM Butterfly Valve, engineered to comply with the stringent JIS F7481 standard and rated for 10 Bar pressure, is a testament to our commitment to reliability, durability, and safety. Designed for Original Equipment Manufacturers (OEMs) in the shipbuilding and marine equipment industry, this valve offers a robust and cost-effective solution for critical onboard systems, ensuring smooth operation even under harsh sea conditions.

This valve is engineered to meet the specific challenges of marine applications. Its design and construction focus on corrosion resistance, tight shut-off, and ease of operation, which are paramount for vessel safety and efficiency.

Key Features & Technical Advantages:

JIS F7481 Compliance: Specifically designed and tested to meet the Japanese Industrial Standard for marine butterfly valves, ensuring compatibility and reliability in global shipbuilding projects.
Robust Pressure Handling: With a pressure rating of 10 Bar (PN16), this valve is suitable for a wide range of shipboard services, including cooling water, ballast, bilge, and fire main systems.
Superior Corrosion Resistance: Available in a variety of body and disc materials such as cast iron with epoxy coating, bronze, and stainless steel (316/316L) to withstand corrosive seawater and marine atmospheres.
Reliable Sealing Performance: Features high-quality elastomer seats (EPDM, NBR) or PTFE, providing excellent bubble-tight shut-off and long service life, minimizing leakage risks.
Versatile Operation: Can be supplied with manual lever handles, gear operators, or automated actuators (electric/pneumatic) for remote or centralized control, enhancing operational flexibility.
Compact & Lightweight Design: The wafer-style design (also available in lug type) saves space and reduces weight compared to gate valves, a crucial factor in marine engineering.
Low Maintenance: Simple design with few moving parts ensures easy inspection, maintenance, and replacement, reducing downtime and lifecycle costs.

Frequently Asked Questions (FAQ):

Q: What does JIS F7481 compliance mean for my marine application?
A: JIS F7481 is a Japanese Industrial Standard specifically for marine butterfly valves. Compliance ensures the valve's design, dimensions, materials, and pressure-temperature ratings are suitable for shipboard use, offering reliability and acceptance in international marine projects.
Q: Can this valve handle seawater directly?
A: Yes, when specified with appropriate corrosion-resistant materials like bronze or stainless steel 316/316L for the body and disc, along with compatible seat materials like EPDM or Viton, it is engineered to handle seawater, ballast water, and other corrosive marine fluids effectively.
Q: Is the 10 Bar rating sufficient for ship firefighting systems?
A> The 10 Bar (PN16) rating is commonly suitable for many marine fire main systems. However, specific system design pressure should always be verified. We can advise on or provide valves with higher pressure ratings if required.
Q: What actuation options are available?
A> We offer a full range: simple manual lever handles for easy local operation, worm gearboxes for higher torque applications, and electric or pneumatic actuators for automated, remote control integration into the ship's control system.
Q: Do you provide certificates for the valves?
A> As an ISO9001-certified manufacturer, we provide a Material Test Certificate (MTC) for the valves. Specific product certifications can be discussed based on project requirements.
Q: What is the typical delivery time for an OEM order?
A> Lead time depends on order quantity, material selection, and customization level. For standard configurations, we generally maintain efficient production schedules. Please contact us with your specifications for an accurate timeline.
Q: Can you customize the valve face-to-face dimensions to match other standards?
A> Yes. While standard dimensions follow JIS F7481/ISO 5752 Series 20, we can customize the face-to-face length to match other standards like ANSI, DIN, or specific OEM drawings upon request.
Q: What are the main ports you ship from?
A> We primarily ship from Shanghai, Guangzhou, Hong Kong, and Beijing ports, offering flexible logistics options to meet the needs of global shipyards and marine equipment distributors.
