The DN100-25 CF8 Flanged Gate Valve is a high-quality, durable valve designed for industrial use, particularly in applications requiring precise flow control in water, oil, gas, and petrochemical systems. Made from CF8 stainless steel, it offers superior corrosion resistance, strength, and longevity.
This valve features a soft sealing design with PTFE or RPTFE seats, ensuring tight shut-off and leakage prevention even under high-pressure conditions. The non-rising stem design is ideal for installations where space is limited, and the flanged connection allows for easy integration into piping systems.
With pressure ratings up to PN40 and availability in multiple sizes (DN25 to DN100), the DN100-25 CF8 Flanged Gate Valve is perfect for use in power plants, water treatment facilities, petrochemical industries, and other sectors where high-performance gate valves are required. The valve is available with manual, gear, electric, or pneumatic actuators for flexible operation.
This valve is built in compliance with international standards, including API 600 and ASME B16.34, ensuring reliable performance and safety in a wide range of demanding applications.
