The main purpose
High-temperature and high-pressure cast steel gate valves are suitable for steam-water medium pipelines and medium pipelines such as petroleum, chemical and metallurgy under various working conditions, and are used for shutting off and isolating the medium. Compared with other valve products, this series is characterized by high temperature and high pressure resistance and a unique self-sealing design. The higher the pressure, the more reliable the sealing.
Features
• The valve adopts a pressure self-sealing structure, and the high-temperature valve uses an anti-burning graphite self-sealing ring, which ensures reliable sealing and long service life;
• The surface of the valve stem has been treated with anti-corrosion treatment, which has good corrosion resistance and scratch resistance, effectively reducing the opening and closing torque, making the valve operation easier;
• Use braided and reinforced graphite combined fillers to improve sealing strength while meeting sealing performance;
• The gate plate can be a wedge-type elastic single gate plate, a screw-in wedge type double gate plate structure or a parallel double expansion plate structure;
• Driving modes are available: manual, electric, pneumatic, turbine transmission and other driving modes.
