As a dedicated manufacturer with ISO9001 certified quality management, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our CCS Approved GB/T5744-1993 Quick Closing Valve. Designed specifically for critical marine safety applications, this valve ensures rapid isolation of fuel or other hazardous media lines in emergency situations, protecting vessels and crew. Our extensive experience since 2016, coupled with an annual export value reaching up to US$1.5 Million, underscores our commitment to delivering reliable, compliant marine safety solutions to a global clientele spanning from North America to Southeast Asia.

This marine emergency safety valve is engineered to meet the stringent requirements of the Chinese standard GB/T5744-1993 and carries the vital CCS (China Classification Society) approval, a key credential for marine equipment. It is available in both straight and angle type configurations to suit diverse pipeline layouts onboard ships. The primary function is to automatically and swiftly close upon receiving a trip signal (e.g., from a fire detection system or manual station), preventing the spread of fire or hazardous fluid leaks.

Key Features & Technical Advantages:

Rapid Emergency Response: The valve actuator is designed for fast closure, typically within seconds, to minimize risk in critical scenarios.
Dual Configuration Options: Choose between straight-through or angle-type bodies to optimize space and piping design in engine rooms and fuel lines.
Robust Construction: Manufactured from high-grade materials such as cast steel, stainless steel, or bronze to withstand harsh marine environments, including corrosion and high pressure.
Fail-Safe Operation: Often designed as normally open valves that close automatically upon loss of control signal or power, ensuring safety even during system failures.
Manual Override: Equipped with a manual closing mechanism for testing or emergency operation independent of the control system.
Versatile Application: Primarily installed in fuel oil, lubricating oil, and other flammable liquid supply lines on various vessels.

Frequently Asked Questions (FAQ):

Q: What is the main purpose of this quick closing valve?
A: Its primary purpose is to act as an emergency safety device on ships. It automatically and rapidly closes to stop the flow of fuel or other hazardous fluids in the event of a fire or other emergency, helping to contain the hazard.
Q: Why is CCS approval important for this valve?
A: CCS (China Classification Society) is one of the major international classification societies. Approval from CCS indicates that the valve has been tested and certified to meet specific marine safety standards, which is often a mandatory requirement for equipment installed on CCS-classed vessels and is widely recognized by other societies.
Q: Can this valve be operated manually?
A: Yes, most models include a manual override or manual closing mechanism. This allows crew members to close the valve directly for testing purposes or during an emergency if the automatic control system is unavailable.
Q: What are the typical actuation methods available?
A: The valve can be equipped with pneumatic, hydraulic, or solenoid (electrical) actuators. The choice depends on the available power source and control system design on the vessel. The specific type can be customized upon request.
Q: How do I choose between the straight type and the angle type?
A: The choice is primarily based on your piping layout. A straight (globe) type is used in-line where the flow direction is straight. An angle type (90-degree) is used where the pipeline needs to make a right-angle turn, saving space and fittings.
Q: What materials are commonly used, and how do I select one?
A: Common body materials include cast steel (WCB) for general service, stainless steel (CF8/CF8M) for corrosive environments, and bronze for specific applications. Selection depends on the fluid media, pressure, temperature, and environmental conditions (e.g., seawater exposure).
Q: What is the typical closing time for this emergency valve?
A: The closing time is designed to be very fast, usually within a few seconds from receiving the trip signal. The exact time can vary based on valve size, actuator type, and system pressure, and detailed performance data is available upon request.
Q: Do you provide documentation for classification society approval?
A: Yes, as a manufacturer supplying CCS-approved products, we provide the necessary certification documents (e.g., Type Approval Certificate, test reports) required for submitting to classification societies during vessel surveys and construction.
