The main purpose

High temperature and high pressure cast steel stop valves are widely used in steam and water medium pipelines under various working conditions and medium pipelines in petroleum, chemical industry, metallurgy, etc., 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 body is formed by casting process, with good flow streamline, meeting the requirements of high, medium, low pressure and large diameter;

• The valve body and valve cover adopt a self-tightening sealing structure. The higher the pressure, the better the sealing performance;

• The sealing surface is made of cobalt-based cemented carbide to ensure high hardness and poor hardness, wear and corrosion resistance, and effectively extend the service life;

• The valve stem rises and falls directly, opening and closing easily, reducing instantaneous friction, effectively protecting the seal and extending its 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 and making the operation easier;

• Driving mode: manual, electric, pneumatic and other driving modes.
