As a specialized manufacturer with years of experience serving the global marine industry, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our premium Marine Electric Gate Valve. Engineered to meet the rigorous demands of shipboard applications, this valve is manufactured in strict conformity with the JIS F7363 specification, ensuring reliability and safety in critical marine piping systems. We combine robust construction with precise electric actuation to deliver a valve solution that enhances operational efficiency and reduces maintenance burdens for shipbuilders, shipyards, and vessel operators worldwide. Every valve is backed by a comprehensive Mill Test Report, providing full traceability and quality assurance from raw material to finished product.
Our Marine Electric Gate Valve is designed for superior performance in seawater, ballast, fuel oil, and other essential shipboard services. The integration of a reliable electric actuator allows for remote operation and easy integration into automated control systems, a crucial feature for modern vessels.
Key Features & Technical Advantages:
- JIS F7363 Compliance: Manufactured to meet all requirements of the Japanese Industrial Standard for ship valves, ensuring international acceptance and compatibility.
- Robust Electric Actuation: Features a durable electric actuator suitable for marine environments. Options include standard on/off control or modulating control for precise flow regulation.
- Full Traceability: Each valve is supplied with a detailed Mill Test Report (MTR), documenting chemical composition, mechanical properties, and non-destructive test results.
- Corrosion-Resistant Materials: Constructed from marine-grade materials such as cast steel with epoxy coating, stainless steel (CF8M/CF3M), or bronze to withstand harsh seawater and atmospheric conditions.
- Bubble-Tight Shut-off: Precision-machined seat and disc design ensures reliable, leak-free closure, essential for system integrity and environmental protection.
- Easy Maintenance: Designed with a repairable body and accessible internals, minimizing downtime and lifecycle costs.

Frequently Asked Questions (FAQ)
-
Q: What is the significance of the JIS F7363 specification for marine valves?
A: JIS F7363 is a Japanese Industrial Standard specifically for steel and cast steel gate valves used in ships. Compliance ensures the valve meets defined requirements for design, materials, pressure-temperature ratings, testing, and marking, which are widely recognized by marine classification societies globally. -
Q: Is the Mill Test Report (MTR) provided for each valve, or per batch?
A: We provide a detailed Mill Test Report for each individual valve or per heat/lot of material, offering full traceability. This is a standard part of our documentation package. -
Q: Can the electric actuator be customized for different voltage supplies or control signals?
A> Yes, customization is available. We offer actuators compatible with various AC/DC voltages (e.g., 24VDC, 110VAC, 220VAC, 380VAC) and can provide options for open/close signals, feedback signals (position indication), and modulating control (4-20mA input). -
Q: What materials are recommended for seawater service?
A: For seawater applications, we typically recommend Stainless Steel 316/316L for the body and internals, or bronze. For higher corrosion resistance, super duplex stainless steel or nickel-aluminum bronze can be offered as optional materials. -
Q: Are these valves approved by major marine classification societies?
A> While our manufacturing process is ISO9001 certified, specific product approvals from societies like ABS, DNV, LR, etc., are generally obtained by the shipyard or client as part of their project certification. We can supply all necessary documentation (MTR, material certs, test reports) to support the approval process. -
Q: What is the typical lead time for an order?
A: Lead time depends on the valve size, material, and quantity. Standard configurations typically have a shorter lead time. Please contact us with your specific requirements for an accurate production schedule. -
Q: Do you offer valves with different flange standards, like ANSI or DIN?
A: Absolutely. While conforming to JIS F7363 for design and performance, we can manufacture the valve with flanges per JIS, ANSI, DIN, or other standards as required by your piping system specifications. -
Q: What after-sales support and warranty do you provide?
A: We offer a standard warranty on our valves and actuators. Additionally, we provide technical support for installation and operation. Spare parts such as gland packing, gaskets, and seal kits are available for purchase to ensure long-term maintenance.
