Custom JIS Gate Valves for Shipbuilding, Available With Rising/Non-Rising Stem
Product Spotlights
As a professional manufacturer with a strong foothold in the global valve market, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing high-performance, reliable fluid control solutions for demanding industries. Our custom JIS Gate Valves are engineered specifically for the rigorous requirements of shipbuilding and marine applications. We understand that reliability under pressure, corrosion resistance, and long-term durability are non-negotiable in marine environments. That's why we offer tailored valves with your choice of rising or non-rising stem designs, ensuring optimal performance and ease of maintenance for your specific piping systems.
Core Features & Technical Advantages:
- JIS Standard Compliance: Manufactured in strict accordance with Japanese Industrial Standards (JIS), ensuring seamless integration with international shipbuilding specifications and compatibility with existing JIS-standard piping networks.
- Dual Stem Design Options: Choose between Rising Stem and Non-Rising Stem configurations. The rising stem design provides a visual indicator of valve position and is often preferred for above-deck applications. The non-rising stem is ideal for spaces with vertical limitations.
- Robust Construction for Marine Use: We utilize premium materials such as cast steel, ductile iron, and stainless steel to combat the corrosive effects of seawater and ensure structural integrity under high pressure.
- Superior Sealing Performance: Featuring metal-to-metal seating, our gate valves offer excellent shut-off capabilities, minimizing leakage and ensuring safe isolation of fluid lines, which is critical for ship safety and operational efficiency.
- Customizable Specifications: Beyond stem type, we can tailor pressure ratings (JIS 10K, 16K, 20K), dimensions, and material grades to meet the exact specifications of your project.

Frequently Asked Questions (FAQ)
-
Q: What is the main difference between a rising stem and a non-rising stem gate valve?
A: In a rising stem valve, the stem threads are outside the valve body, and the stem rises as the valve opens, providing a clear visual indication of position. A non-rising stem valve has internal threads; the stem rotates but does not move vertically, making it suitable for installations with limited vertical space. -
Q: Are your JIS Gate Valves suitable for seawater applications?
A: Yes, when specified with appropriate corrosion-resistant materials like stainless steel (CF8M for better chloride resistance) or specially coated cast steel, our valves are well-suited for handling seawater and other corrosive marine fluids. -
Q: Can you provide valves with pressure ratings other than JIS 10K/16K/20K?
A: While JIS 10K, 16K, and 20K are standard, we can discuss custom pressure classes based on your specific design requirements. Please provide the detailed specifications for evaluation. -
Q: Do you offer actuated versions of these gate valves?
A: Yes, electric, pneumatic, or hydraulic actuators can be fitted to our JIS gate valves for remote or automated operation. This is an optional feature available upon request. -
Q: What is your typical lead time for custom JIS gate valves?
A: Lead time depends on the order quantity, material selection, and customization level. Generally, it ranges from 4 to 8 weeks. We provide a confirmed schedule upon order placement. -
Q: What documentation do you provide with the valves?
A> We provide essential documentation including Material Test Certificates (MTC), inspection reports, and a manual. Certificates of Conformity to JIS standards are also available. -
Q: How do you ensure the quality of your valves?
A> Our manufacturing process is governed by an ISO9001 quality management system. Each valve undergoes rigorous pressure testing, dimensional checks, and visual inspection before shipment. -
Q: Which ports do you ship from, and what are the payment terms?
A> We ship from major ports including Shanghai, Guangzhou, Hong Kong, and Beijing. Standard payment terms are T/T or L/C, but we are open to discussion based on order value and mutual agreement.
