DN100 (4 Inch) Pneumatic Ball Valve – Automated Ball Valve for Industrial Process Control

✅ DN100 (4-inch) Pneumatic Ball Valve is an automated valve assembly consisting of an industrial ball valve and a pneumatic actuator, designed to provide fast, reliable, and efficient on/off control of industrial process media. It is widely used in water treatment, compressed air systems, steam lines, oil and gas, chemical processing, food production, and automated manufacturing facilities.

✅ Powered by compressed air, the pneumatic actuator converts air pressure into a precise 90-degree rotary motion, allowing the valve to open or close quickly. Compared with manual operation, pneumatic automation improves productivity, enhances operational safety, and reduces labor costs.

✅ The valve body is commonly manufactured from SS304 stainless steel, SS316 stainless steel, or WCB carbon steel, making it suitable for a wide range of industrial applications. The precision-machined ball combined with PTFE (Teflon) or RPTFE seats ensures excellent sealing performance, low operating torque, and extended service life.

✅ The pneumatic actuator utilizes a durable Rack & Pinion mechanism housed in a hard anodized aluminum body. It is available in both Double Acting (DA) and Spring Return (SR) configurations to meet different automation and fail-safe requirements.

✅ The DN100 (4-inch) valve is available with JIS 10K, ANSI Class 150, or DIN PN16 flanged connections, allowing compatibility with most industrial piping systems. It can also be equipped with accessories such as solenoid valves, limit switch boxes, positioners, and air filter regulators for complete automated valve control.

✅ With fast response, reliable shut-off performance, excellent corrosion resistance, and long service life, the DN100 pneumatic ball valve is an ideal solution for modern industrial automation systems requiring dependable flow control.
