The Kitz Class 300 flanged gate valve is manufactured with a steel or ductile iron body and rated for Class 300 pressure according to ASME B16.34. It operates as a gate valve with a linear sliding disc mechanism, providing full open or closed flow control, not suitable for throttling. Internal components, including the disc and seat, are made of stainless steel or bronze for high corrosion and wear resistance, capable of handling operating temperatures between 0°C and 425°C. The flanged design conforms to ASME B16.5 standards, enabling secure and rapid installation between standard flanged pipelines. Internal sealing with high-performance washers ensures minimal leakage and quiet, reliable operation.
Depending on nominal size DN50–DN600, the valve weight ranges from 25 to 450 kilograms. The body and disc are designed to withstand pressure surges and impacts, making it suitable for water, steam, oil, and other industrial and chemical fluids. Flanges feature standard bolt patterns and corrosion-resistant coating for long-term protection and ease of installation. The Kitz Class 300 flanged gate valve offers robust construction, long service life, and safe operation, making it a primary choice for oil, gas, power plants, and high-pressure industrial pipelines.

To install a Class 300 Kitz flanged gate valve, first completely shut off system flow and release internal pressure. The valve should be installed horizontally or vertically with full pipe support to prevent excess load on the body. Flanges must be tightened with a torque of 150 Nm, using PTFE or graphite gaskets according to ASME B16.5. After installation, operate the valve several times to ensure smooth performance and zero leakage. Lubricating the valve stem with high-temperature grease up to 250°C guarantees precise operation and a lifespan exceeding 100,000 cycles. Compliance with ISO 5211 and API 608 standards enhances safety and efficiency in industrial systems.
