As a specialized manufacturer with a strong global footprint, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our high-performance JIS F7301 Pneumatic Actuated Ball Valve. Engineered for reliability in demanding industrial environments, this valve combines the robust construction of a 304 stainless steel body with the superior sealing properties of PTFE seats. Our years of experience since 2016 and adherence to ISO9001 quality management systems ensure that every valve delivers precise flow control, long service life, and minimal maintenance requirements, making it a smart investment for your critical piping systems worldwide.
This valve is designed to meet the stringent requirements of the Japanese Industrial Standard JIS F7301, guaranteeing compatibility and performance in a wide range of applications. The pneumatic actuation provides fast, reliable, and automated on/off or modulating control, ideal for processes where remote operation or integration into a control system is essential.
Key Features and Technical Advantages:
- Durable 304 Stainless Steel Body: Offers excellent corrosion resistance against a wide variety of media, including water, steam, oil, gas, and many corrosive chemicals, ensuring longevity even in harsh environments.
- High-Performance PTFE Seats: Polytetrafluoroethylene seats provide exceptional sealing, low friction, and broad chemical compatibility. They are self-lubricating and can handle a wide temperature range, contributing to tight shut-off and reduced wear.
- Pneumatic Actuator Compatibility: The valve is outfitted for easy mounting of double-acting or spring-return pneumatic actuators. This allows for fail-safe operation (open or closed) in case of air supply loss, a critical feature for safety and process integrity.
- JIS F7301 Flanged Connection: Ensures easy and secure installation into pipelines adhering to Japanese and similar international standards, facilitating integration into existing systems, particularly in Asian and global markets.
- Bubble-Tight Shut-Off: The precision-machined ball and PTFE seat combination is engineered to achieve bubble-tight sealing, minimizing leakage and ensuring process efficiency and environmental safety.
- Low Torque Operation: The design of the ball valve and the low-friction PTFE seats result in lower operating torque, which allows for the use of smaller, more cost-effective pneumatic actuators and reduces energy consumption.
- Versatile Applications: Suitable for a vast array of industries including chemical processing, petrochemical, pharmaceutical, food and beverage, water treatment, and general industrial automation.

Frequently Asked Questions (FAQ)
Q1: What are the main advantages of a pneumatic actuated ball valve over a manual one?
A: Pneumatic actuation allows for remote, automated control which is faster, more repeatable, and easily integrated into PLC or DCS systems. It enables operation in hard-to-reach or hazardous locations and facilitates complex sequencing, improving overall process efficiency and safety.
Q2: Is the 304 stainless steel body suitable for seawater or highly chloride environments?
A: While AISI 304 stainless steel offers good general corrosion resistance, for prolonged exposure to seawater or high chloride concentrations, AISI 316 or 316L stainless steel is often recommended due to its higher molybdenum content. We can provide valves with 316/316L bodies upon request.
Q3: Can this valve be used for throttling or flow control applications?
A: Standard quarter-turn ball valves like this one are primarily designed for on/off service. While they can be used for rough throttling, it may lead to premature seat wear and cavitation. For precise modulating control, a characterized ball valve or a different valve type (like a globe valve) with a pneumatic actuator and positioner would be more suitable.
Q4: What is the difference between double-acting and spring-return pneumatic actuators?
A: A double-acting actuator uses air pressure to move the valve in both directions (open and close). A spring-return (single-acting) actuator uses air pressure to move in one direction and a built-in spring to return to its default position (normally open or normally closed) upon air loss, providing a fail-safe function.
Q5: Are the PTFE seats compatible with all chemicals?
A: PTFE has one of the broadest chemical compatibilities of any polymer and is resistant to most aggressive media. However, it is not recommended for use with molten alkali metals, certain fluorine compounds, and some halogenated solvents at high temperatures. Always consult chemical compatibility charts for your specific media.
Q6: Do you provide the complete assembly including the pneumatic actuator?
A: Yes, we typically supply the valve as a complete package, including the ball valve body, the pneumatic actuator (double-acting or spring-return as specified), and the necessary mounting hardware. We can also include accessories like solenoid valves, limit switches, and positioners.
Q7: What information do I need to provide to get an accurate quote?
A: Please provide the valve size (DN/NPS), pressure rating (JIS 10K/20K or PN/Class), required actuator type (double-acting or spring-return with fail-safe position), air supply pressure, and any special requirements like accessory packages or material upgrades.
Q8: What is the typical lead time for orders, and what are the payment terms?
A: Lead times vary based on order quantity and specifications. Standard configurations typically have shorter lead times. We offer flexible payment terms such as T/T and L/C, which can be discussed in detail after we receive your specific inquiry.
