As a leading manufacturer with a strong presence in global markets from North America to Southeast Asia, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present the IS F7399 Bronze Manual Quick Closing Valve. Engineered for reliability and rapid response, this valve is designed to provide immediate flow shutoff in critical industrial and commercial piping systems. Our commitment to quality, backed by ISO9001 certification, ensures that every valve meets stringent performance standards, offering our international clients a dependable solution for managing steam, water, oil, and gas services. With an annual export value reflecting our global reach, we deliver products that combine robust construction with operational simplicity.
The IS F7399 valve is characterized by its quick-closing mechanism, which allows for almost instantaneous shutoff with a quarter-turn of the handle. This feature is crucial in applications where rapid isolation is necessary for safety or process control. The valve body is constructed from high-grade bronze, offering excellent corrosion resistance and durability in a wide range of environments. The internal components are precision-machined to ensure a tight seal and smooth operation over thousands of cycles.
- Rapid Shutoff Capability: The quarter-turn design enables full open to full close in less than one second, minimizing response time during emergencies or process adjustments.
- Durable Bronze Construction: Manufactured from corrosion-resistant bronze alloys, the valve withstands demanding service conditions involving water, steam, and non-corrosive gases and oils.
- Reliable Sealing Performance: Features a resilient seat (PTFE or Buna-N options) that provides a bubble-tight seal, preventing leakage and ensuring system integrity at the rated 150 PSI.
- Ergonomic Manual Operation: Equipped with a clearly marked, easy-grip handle that provides positive visual indication of valve position (open/closed).
- Versatile Port Connections: Available with threaded (NPT, BSP) or flanged ends to suit various piping system requirements, facilitating easy installation and integration.
- Broad Temperature Compatibility: Operates effectively across a temperature range from -20°C to 120°C, making it suitable for both heating and cooling applications.

For buyers, the primary benefits of selecting the IS F7399 valve include enhanced system safety through rapid isolation, reduced maintenance costs due to its durable construction and reliable seal, and simplified inventory management thanks to its versatility across multiple fluid services. Its straightforward manual operation eliminates the need for complex actuators or power sources, making it a cost-effective and fail-safe choice for many applications.
Frequently Asked Questions (FAQ)
Q1: What is the main advantage of a "quick closing" valve compared to a standard gate or globe valve?
A1: The primary advantage is speed. A quarter-turn operation allows for almost instantaneous shutoff, which is critical for emergency isolation, process safety, or where frequent on/off cycling is required. Standard multi-turn valves take significantly longer to close.
Q2: Is the 150 PSI rating a cold working pressure (CWP) or a working pressure at a specific temperature?
A2: The 150 PSI rating is the maximum recommended working pressure at the valve's upper temperature limit of 120°C. The pressure rating may be higher for lower temperature services. Please consult the manufacturer's pressure-temperature chart for specific conditions.
Q3: Can this valve be used for steam service?
A3: Yes, the IS F7399 is suitable for saturated steam service within its specified pressure and temperature ratings (up to 150 PSI @ 120°C). The bronze construction and PTFE seat provide good compatibility.
Q4: What are the available end connections?
A4: The valve is commonly supplied with threaded ends (NPT or BSP). Flanged ends to standards like ANSI B16.5 may be available upon request. Please specify your connection requirement when inquiring.
Q5: Is the valve position (open/closed) clearly indicated?
A5: Yes. The operating handle is designed to provide a clear visual indication. When the handle is aligned with the pipe, the valve is open. When it is perpendicular, the valve is closed.
Q6: What maintenance does this valve require?
A6: The valve is designed for minimal maintenance. Periodic lubrication of the stem threads (if externally threaded) and inspection of the handle and seal for wear is recommended. The seat and seal may be replaceable depending on the specific model configuration.
Q7: Can the valve be locked in the open or closed position?
A7: Many models feature a hole in the handle or stem that can accommodate a padlock for locking out the valve in a safe position (Lockout/Tagout - LOTO procedures), but this should be confirmed for the specific size and model ordered.
Q8: What is the typical lead time for orders?
A8: Lead times vary based on order quantity, size, and connection specifications. Standard sizes are often available from stock. For specific delivery timelines, please contact our sales team with your detailed requirements.
