Our ball valves are engineered to meet the stringent requirements of the Japanese Industrial Standard (JIS) F7301, ensuring compatibility and performance in international projects. The choice between 304 and 316L stainless steel materials allows customers to select the optimal corrosion resistance for their specific environment, whether facing general chemical exposure or highly corrosive conditions.
Key Features and Technical Specifications:
- Compliance & Quality Assurance: Manufactured to JIS F7301 standards. Each valve is produced under an ISO9001 certified process, and a Mill Test Report is provided to certify the material composition and properties.
-
Material Options: Available in two premium stainless steel grades:
- AISI 304 Stainless Steel: Offers good corrosion resistance and mechanical properties for general industrial use.
- AISI 316L Stainless Steel: Provides enhanced corrosion resistance, particularly against chlorides and acids, suitable for more aggressive environments.
- Design for Performance: Features a full port or standard port design (customizable) for optimal flow efficiency. The ball and stem assembly is designed for low torque operation and smooth shut-off.
- Sealing System: Utilizes durable sealing materials such as PTFE or reinforced PTFE (options available) to ensure a tight seal and long service life across a wide temperature range.
- Connection Versatility: Can be supplied with threaded (NPT, BSP) or flanged (JIS, ANSI) end connections based on customer requirements.
- Operational Benefits: Provides quick and easy on/off control, minimal pressure drop, and suitability for a wide range of fluids including water, oil, gas, and certain chemicals.

Frequently Asked Questions (FAQ):
-
Q: What is the significance of the JIS F7301 standard for this ball valve?
A: JIS F7301 is a Japanese Industrial Standard specifying requirements for steel valves. Using a valve compliant with this standard ensures it meets defined dimensions, materials, pressure ratings, and testing criteria, which is important for projects specifying JIS or requiring interoperability with Japanese equipment. -
Q: What exactly is a Mill Test Report, and why is it important?
A: A Mill Test Report (MTR) is a certificate from the steel mill that produced the raw material. It details the chemical composition and mechanical properties (like tensile strength) of the stainless steel used in the valve. It provides traceability and proof that the material meets the specified grade (304 or 316L), which is vital for quality assurance and regulatory compliance. -
Q: How do I choose between 304 and 316L stainless steel?
A: The choice depends on the operating environment. AISI 304 is suitable for general purposes with good corrosion resistance. AISI 316L contains molybdenum, offering superior resistance to corrosion from chlorides, acids, and salty environments. For applications involving seawater, certain chemicals, or high chloride content, 316L is often recommended. -
Q: Can these valves be customized for specific pressure ratings or end connections?
A: Yes, customization is available. While the valve conforms to JIS F7301, specific pressure ratings (like PN16, PN25) and end connection types (threaded NPT/BSP, flanged JIS/ANSI dimensions) can be tailored based on your project requirements. Please provide your specifications when inquiring. -
Q: What seal materials are used, and are there options?
A: Standard seals are typically made from PTFE (Polytetrafluoroethylene), which offers good sealing and a wide temperature range. Enhanced PTFE or other seal materials may be available as options for specific fluid compatibility or temperature needs. Discuss your application details for the best recommendation. -
Q: From which ports can the valves be shipped?
A: We can arrange shipment from major Chinese ports including Shanghai, Guangzhou, Hongkong, and Beijing. This flexibility helps optimize logistics and delivery timelines to your destination. -
Q: Is the ISO9001 certification relevant to the product quality?
A: Yes. Our ISO9001 certification for Quality Management Systems means our manufacturing processes, from material procurement to final inspection, follow documented and controlled procedures. This systematic approach contributes to consistent product quality and reliability. -
Q: What are the typical applications for this type of ball valve?
A: These stainless steel ball valves are suitable for controlling the flow of various fluids in industries such as water treatment, chemical processing, food and beverage (with appropriate material selection), HVAC, marine, and general industrial piping systems where corrosion resistance and reliable shut-off are required.
