As a professional manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our JIS F7399 WCB Material Straight Pneumatic Quick Closing Valve, engineered for reliable and rapid flow isolation in demanding industrial and marine applications. Designed to operate at a standard 10 Bar pressure, this valve combines robust construction with precise pneumatic actuation, ensuring safety and operational efficiency for your critical piping systems. Established in 2016 and serving a global market from North America to Southeast Asia, we understand the need for dependable fluid control solutions that meet stringent international standards.

This valve is specifically designed for scenarios requiring immediate shut-off to prevent accidents or equipment damage. Its core function is to provide a fast, fail-safe closure upon receiving a pneumatic signal or upon loss of control pressure.

Key Features & Technical Advantages:

Rapid Closure Mechanism: The pneumatic actuator is optimized for quick response, significantly reducing the valve closure time compared to manual or other actuated valves, which is crucial for emergency shutdown (ESD) systems.
Robust WCB Body Construction: Manufactured from ASTM A216 WCB carbon steel, the valve body offers excellent strength and durability, suitable for a wide range of industrial fluids including water, steam, oil, and gas under high-pressure conditions.
JIS F7399 Standard Compliance: Conformity to the Japanese Industrial Standard for marine quick-closing valves ensures high quality, reliability, and interchangeability, making it a preferred choice for shipbuilding and related industries.
Fail-Safe Design: Typically configured as spring-return, the valve automatically closes (or opens, depending on specification) upon loss of pneumatic supply, enhancing system safety.
Precise Sealing: Equipped with a stainless steel seat and resilient seal, the valve provides bubble-tight shut-off, minimizing leakage and ensuring process integrity.
Low Maintenance: The simple yet robust design reduces the need for frequent maintenance, while accessible internal components facilitate easier servicing when required.

Frequently Asked Questions (FAQ):

Q: What is the primary application of this quick-closing valve?
A: It is primarily used in marine piping systems (e.g., fuel oil, lubricating oil lines) and industrial plants for emergency shutdown (ESD) applications where rapid flow isolation is essential for safety.
Q: Can this valve be used with media other than those listed?
A: The standard WCB body and stainless steel seat suit many common fluids. For highly corrosive or specialized media, please consult us for material alternatives like CF8M (316 stainless steel) which may be available.
Q: What is the typical valve closure time?
A> The closure time depends on valve size, actuator configuration, and supply pressure. Generally, pneumatic actuation allows for closure within a few seconds. Specific timing data for your chosen size can be provided upon request.
Q: Is the fail-safe action normally closed (NC) or normally open (NO)?
A> This is configurable. The standard offering is typically spring-return to close (normally closed) upon air failure, but a normally open configuration can also be supplied. Please specify your requirement when ordering.
Q: Are other port connection standards available besides JIS flanges?
A> Yes. While compliant with JIS F7399, we can often provide valves with ANSI, DIN, or GB standard flanges to match your existing piping. This is a customizable option.
Q: What accessories are needed for operation?
A> The valve requires a pneumatic supply line and a solenoid valve or pilot valve for control. Filter-regulator-lubricator (FRL) units are recommended to ensure clean, dry air for optimal actuator longevity. These accessories can be sourced separately.
Q: Do you provide certifications with the valve?
A> As an ISO9001 certified manufacturer, we provide a material certificate (CMTR) and a factory test report (e.g., shell test, seat test) as standard. Specific third-party certifications can be discussed based on project requirements.
Q: What is your lead time for an order?
A> Lead time varies based on order quantity, size, and customization. For standard sizes, typical lead time ranges from 4 to 8 weeks. We provide accurate timelines upon receipt of your detailed inquiry.
