As a professional manufacturer with ISO9001 certified quality management, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing reliable fluid control solutions for global maritime applications. Our GB/T5744-1993 Marine Quick Closing Valve with Manual Reset represents a critical safety component engineered for rapid isolation in marine piping systems. Designed with durability and operational safety as core principles, this valve ensures immediate flow cessation when required, protecting personnel, equipment, and the marine environment. Since our establishment in 2016, we have consistently supplied high-performance valves to markets across North America, South America, Europe, Asia, and beyond, building a reputation for dependable products and service.
The valve's construction and functionality are tailored to meet the stringent demands of marine service. Below are the key technical specifications and design features:
- Robust Stainless Steel Construction: Manufactured from high-grade stainless steel (typically 304 or 316), the valve offers exceptional resistance to corrosion from seawater, saline atmospheres, and various shipboard fluids. This material choice ensures a long service life with minimal maintenance, even in harsh marine environments.
- Manual Reset Mechanism: The valve features a clear, positive-action manual reset function. After a quick-closing event, the valve must be manually reset to the open position, providing a deliberate and verifiable step to restore flow. This design prevents accidental or automatic reopening, which is a crucial safety feature.
- Compliant Quick-Closing Action: Engineered in strict accordance with the GB/T5744-1993 standard, the valve is designed for rapid closure. The mechanism allows the valve to shut off the flow within a specified short timeframe, a vital requirement for emergency isolation in fuel lines, cargo systems, and other critical shipboard pipelines.
- Versatile Flange Connections: Standard models come with flanged ends compatible with common marine piping standards. Connection specifications can be customized upon request to match specific project requirements or regional standards.
- Reliable Sealing Performance: Equipped with high-quality sealing elements suitable for the designated pressure and temperature range, ensuring a bubble-tight seal in the closed position to prevent leaks.

Frequently Asked Questions (FAQ)
-
Q1: What is the main purpose of this quick closing valve?
A1: Its primary purpose is to provide rapid emergency isolation in marine piping systems, such as fuel oil, lubricating oil, or cargo lines, to contain potential hazards like fire or spillage in compliance with safety regulations. -
Q2: Why is a manual reset important?
A2: A manual reset ensures that the valve cannot reopen automatically after an emergency closure. An operator must physically reset it, allowing for a deliberate system check and confirmation that it is safe to resume flow, which is a critical safety procedure. -
Q3: Can this valve be used with media other than oil?
A3: Yes, while commonly used for oils, its stainless steel construction makes it suitable for various other shipboard fluids, including seawater, chemicals, and bilge water, within its specified pressure and temperature ratings. Please consult us for your specific media. -
Q4: Are the flanges compatible with international standards like ANSI or JIS?
A4: Standard production follows common Chinese/GB flange standards. However, we can customize the flange dimensions, drilling, and facing to meet ANSI, JIS, DIN, or other international standards upon request. -
Q5: What maintenance does this valve require?
A5: Due to its stainless steel construction, maintenance requirements are low. Periodic visual inspection for external damage, functional testing of the quick-closing and reset mechanism, and checking seal integrity are recommended as part of routine ship maintenance schedules. -
Q6: Do you provide documentation with the valve?
A6> Yes, typical documentation includes a material certificate, a pressure test certificate, operation and maintenance instructions, and a packing list. Additional certifications can be discussed. -
Q7: What is the typical delivery lead time?
A7: Lead time depends on order quantity and any customization required. For standard models, we generally maintain stock for common sizes, allowing for shorter lead times. We provide specific timelines upon order confirmation. -
Q8: How do you ensure quality control?
A8> Our manufacturing process is governed by an ISO9001 quality management system. Each valve undergoes rigorous inspections, including material checks, dimensional verification, and hydrostatic pressure testing, before shipment.
