As a leading manufacturer with a strong commitment to maritime safety, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our high-performance Pneumatic Quick Closing Valve, engineered specifically for marine fuel oil systems. Designed in strict compliance with the JIS F7399 standard, this valve is a critical safety component, providing rapid and reliable isolation of fuel lines in emergency situations. Our years of expertise, backed by ISO9001 certified manufacturing processes, ensure that each valve delivers the dependable performance demanded by shipbuilders, shipowners, and marine engineers worldwide. This product embodies our dedication to protecting vessels, crew, and the marine environment through superior engineering.

Core Design & Safety Features:

Instant Emergency Response: The valve's primary function is to shut off the fuel supply within seconds upon receiving a trip signal, a vital action for fire prevention and damage control.
Spring-Return Fail-Safe Mechanism: Incorporates a powerful spring that automatically closes the valve upon loss of pneumatic pressure or upon activation of the emergency shutdown (ESD) system, ensuring safety even during power or air supply failure.
JIS F7399 Compliance: Manufactured to meet the rigorous Japanese Industrial Standard for marine quick-closing valves, guaranteeing compatibility, performance, and reliability recognized in global shipbuilding.
Robust Pneumatic Actuation: Utilizes a double-acting pneumatic cylinder for positive opening and closing actions. The actuator is designed for durability in the harsh marine environment.
Bubble-Tight Shut-off: Features precision-machined seat and disc (often with Stellite or stainless steel trim) to ensure a leak-proof seal, preventing fuel drip after closure.
Remote & Local Operation: Can be operated remotely from the engine control room or bridge via solenoid valves, and also features a manual override for local testing and emergency use.

Technical Specifications & Construction:

The valve is built for longevity and minimal maintenance in demanding service conditions. Key construction details include:

Body & Bonnet: Typically constructed from high-grade cast steel (WCB) or ductile iron, offering excellent strength and corrosion resistance.
Trim Materials: Internal wetted parts (disc, seat, stem) are available in various stainless steel grades (304, 316) or special alloys to handle different fuel types and additives.
Flange Connection: Standard JIS 10K or 16K flanges ensure easy integration into existing Japanese-standard or internationally compatible fuel oil piping systems.
Actuator Enclosure: Weatherproof and splash-proof housing protects the pneumatic components from saltwater spray and humidity.

Typical Ordering Parameters:

Parameter	Specification / Option
Nominal Size (DN)	50, 65, 80, 100, 125, 150, 200 mm (Other sizes available)
Pressure Rating	JIS 10K (PN16) / JIS 16K (PN25)
Operating Air Pressure	0.5 - 0.7 MPa (Standard)
Closing Time	< 5 seconds (Typically 2-3 seconds)
Position Indication	Mechanical indicator, with optional limit switches (open/close)
Ambient Temperature	-20°C to +80°C (Extended range customizable)

Benefits for Ship Operators and Builders:

Enhanced Vessel Safety: Directly contributes to meeting SOLAS (Safety of Life at Sea) and class society (e.g., ABS, DNV, LR, NK) requirements for fuel oil system safety.
Reduced Operational Risk: Minimizes the potential for catastrophic engine room fires by enabling rapid fuel cut-off.
Global Regulatory Acceptance: JIS F7399 compliance facilitates approval processes for vessels built in or destined for Asian and international markets.
Reliable Performance: Robust construction and quality components lead to long service intervals and dependable operation, reducing lifecycle costs.
Simplified Procurement & Integration: Standard dimensions and interfaces simplify the sourcing and installation process for shipyards and repair docks.

Frequently Asked Questions (FAQ):

Q: What is the main purpose of this quick closing valve on a ship?
A: Its primary purpose is safety. It is installed in fuel oil lines leading to boilers, engines, and incinerators. In case of fire, rupture, or other emergencies, it can be triggered to instantly cut off the fuel supply, preventing the escalation of the incident.
Q: How is the valve activated?
A: Activation is typically via an electrical signal to a solenoid valve, which vents air pressure from the pneumatic actuator. The built-in fail-safe spring then drives the valve to its closed position automatically. Manual pull-wire or push-button stations are also common for local activation.
Q: Is this valve suitable for heavy fuel oil (HFO)?
A: Yes, it is designed for marine fuel oil systems, including HFO. Material selections for seats, seals, and stems can be specified to handle the viscosity and potential corrosiveness of various fuel grades. Please consult with us for your specific fuel type.
Q: Can you provide valves with different flange standards, like ANSI or DIN?
A: While the standard product is built to JIS F7399 with JIS flanges, we can often accommodate other flange standards (ANSI, DIN, GB) upon request. This may involve modifications to the body casting or use of adaptor flanges.
Q: What maintenance does the valve require?
A: Maintenance is generally minimal. Periodic checks include verifying the pneumatic system for leaks, testing the closing time and function, and lubricating the actuator mechanism as per the manual. The robust design aims for long intervals between major overhauls.
Q: Do you provide documentation for class approval?
A: We can provide standard documentation such as material certificates, pressure test reports, and general arrangement drawings. For specific class society (e.g., ABS, BV) certification, requirements should be discussed in advance as they may involve witnessed testing and additional documentation.
Q: What is the lead time for an order?
A: Lead time depends on the size, material specifications, and order quantity. Standard configurations typically have shorter lead times. We recommend contacting our sales team with your requirements for an accurate production schedule.
Q: How does the manual override function work?
A: The valve is equipped with a manual handwheel or lever on the actuator. This allows crew to manually open or close the valve for isolation during maintenance or if the pneumatic system is unavailable, ensuring operational flexibility.
