The KONTE Pneumatic Japanese Standard Flanged Ball Valve is designed for pipeline systems that follow JIS (Japanese Industrial Standards) specifications. Built with a JIS 10K flanged connection, this ball valve provides reliable shut-off and flow control in sizes from DN15 to DN200. The valve body is produced through an investment casting process, resulting in a dense, uniform metal structure with a clean surface finish.
Pneumatic actuation allows fast, remote-controlled quarter-turn operation. The valve moves from full open to full close with a 90° rotation, making it suitable for automated process lines and systems managed by PLC or DCS platforms. An electric actuator option is also available for installations where compressed air is not accessible.
As a JIS flanged ball valve manufacturer and exporter, KONTE supplies this product to distributors, project contractors, and industrial end users across more than 60 countries. With over 30 years of valve manufacturing experience and a production base exceeding 170,000 m², we offer OEM, ODM, custom manufacturing, and bulk supply services backed by consistent quality and on-time delivery.
▶ Fire resistance and static function.
▶ The anti-valve stem flying out of the structure.
▶ The shell adopts a silicon-soluble casting process with a beautiful appearance.
▶ The cylinder piston actuator and electric actuator are available.
▶ The fluid resistance is small, and its resistance coefficients are equal to the same length.
▶ Simple structure, small size, lightweight.
▶ The cover material of the ball valve uses the Japanese Gold PTFE (M111), which has good sealing, and has been widely used in vacuum systems.
▶ It is easy to operate and quickly and close. From full opening to full level, it only needs to rotate 90 to facilitate long-distance control.
▶ It is convenient for maintenance, the structure of the ball valve is simple, and the sealing ring is generally active. It is more convenient for disassembly and replacement.
▶ When full or full-closed, the seal of the sphere and the valve seat is isolated from the medium. When the medium passes, it will not cause the erosion of the valve cover.
This pneumatic JIS ball valve incorporates a fire-safe structure tested to maintain sealing integrity under high-temperature emergency conditions. The anti-static design ensures electrical continuity between the ball, stem, and body, preventing static charge buildup that could ignite flammable media. These features make the valve suitable for oil, gas, and chemical service where fire and explosion risks exist.
The valve stem is designed with an anti-blowout mechanism. Even if the internal packing fails, the stem cannot be ejected by line pressure. This construction protects both equipment and personnel in high-pressure installations.
The valve body is manufactured through investment casting (lost-wax process). This method produces a smooth surface, tight dimensional tolerances, and a uniform grain structure. It eliminates the porosity and surface defects common in sand-cast bodies, improving both pressure integrity and appearance.
The ball seat uses Japanese-grade PTFE (M111) sealing material. This PTFE compound delivers low friction, broad chemical compatibility, and stable sealing performance across a wide temperature range. It has been proven in vacuum systems and is resistant to most acids, alkalis, and solvents.
A 90° rotation moves the valve between full open and full close positions. This quick-acting mechanism reduces cycle time in automated systems. The pneumatic piston actuator responds within seconds, and the optional electric actuator provides the same quarter-turn function for locations without air supply.

The pneumatic Japanese standard flanged ball valve uses a spherical disc (ball) with a through-hole as the flow control element. When the actuator rotates the ball 90°, the hole aligns with or blocks the pipe bore, switching the valve between open and closed states.
The pneumatic piston actuator converts compressed air pressure into rotational torque. Single-acting (spring return) and double-acting configurations are both available. Single-acting actuators return to a fail-safe position (open or close) when air supply is lost, providing an additional layer of safety for critical process lines.
Position feedback can be added through limit switches, solenoid valves, or positioners, enabling the valve to communicate with central control systems. This makes the KONTE pneumatic JIS ball valve a practical choice for both manual and fully automated industrial valve applications.
The pneumatic JIS 10K flanged ball valve serves a range of sectors where JIS-standard piping is specified.
Shut-off and isolation duties on crude oil pipelines, natural gas distribution networks, and refinery process lines. The fire-safe and anti-static design meets the safety demands of hydrocarbon service.
Handling of acids, alkalis, solvents, and other corrosive media in chemical plants. The PTFE seat and stainless steel body provide the chemical resistance needed for these environments.
Flow control and shut-off in municipal water supply, industrial cooling water, boiler feedwater, and steam distribution systems. The low fluid resistance of the full-bore design minimizes pressure loss across the valve.
Isolation and regulation in thermal and hydroelectric power plants, including condenser cooling circuits, fuel oil lines, and auxiliary water systems.
Any JIS-standard piping system in manufacturing plants, shipbuilding, HVAC, and building services where a flanged ball valve with pneumatic or electric actuation is specified.
Every KONTE JIS flanged ball valve passes through a complete inspection process before shipment. This process includes spectrometer analysis for raw material verification, dimensional checks during CNC machining, and final pressure and air tightness testing in accordance with JIS and API 598 standards. All test results are documented with photographs and stored for more than 10 years.
KONTE holds ISO 9001 quality management system certification along with CE, API, ATEX, SIL, and other international approvals. Our production facilities include over 500 CNC machines and multiple dedicated assembly lines with an annual output capacity exceeding 1 million valve units.
We provide a warranty of 12 months from the shipment date or 18 months from the installation date. Our after-sales team responds to complaints within 8 working hours, with finalized solutions delivered within 24 hours. Emergency cases receive priority handling within 4 hours.
KONTE also operates 15 overseas warehouses across Asia, Europe, and the Americas, enabling local stock availability and faster delivery for distributors and project contractors.
A JIS 10K ball valve is a ball valve built to Japanese Industrial Standards with a 10K pressure class flanged connection. The "10K" designation indicates the valve is rated for a specific working pressure as defined by JIS B2071 or JIS B2072. This standard is widely used in Japan, Southeast Asia, and other regions where JIS piping systems are installed.
A pneumatic actuator uses compressed air (typically 4–6 bar) to drive the valve open or closed. It offers fast response and fail-safe capability with spring-return configurations. An electric actuator uses an electric motor and does not require an air supply, making it suitable for remote locations or systems without compressed air infrastructure. KONTE offers both options for this JIS flanged ball valve.
