Hard sealed high temperature and high pressure butterfly valve, wear-resistant and corrosion-resistant industrial pipeline valve, hard collision

Description :

This high-temperature and high-pressure butterfly valve is designed for harsh working conditions, using a hard sealed structure that can withstand extremely high temperature and pressure impacts. The valve plate and valve seat are precision ground and tightly matched to ensure good sealing performance even in long-term high-temperature environments. Suitable for steam, flue gas, and high-temperature medium pipeline control in industries such as power, metallurgy, and chemical engineering, effectively solving the problem of aging and leakage of traditional soft sealed butterfly valves at high temperatures.

The valve body is made of high-quality cast steel or stainless steel, which has high strength and strong corrosion resistance. The surface of the butterfly plate is welded with hard alloy, which is wear-resistant, erosion resistant, and has a long service life. The driving mode can be equipped with manual, worm gear, pneumatic or electric actuators, which are flexible in operation and have fast response speed. The structural design is compact, lightweight, easy to install, and saves pipeline space. Bidirectional sealing design eliminates the need to consider the flow direction of the medium during installation, reducing construction difficulty and maintenance costs.

Under high temperature and high pressure conditions, the thermal expansion compensation mechanism of the valve can automatically adjust the sealing pressure ratio to prevent jamming or leakage caused by thermal expansion and contraction. The valve stem adopts an anti blowout structure, combined with multi-layer graphite packing, to ensure zero external leakage. Optimization of channel design, low flow resistance coefficient, high flow capacity, and significant energy-saving effect. After rigorous high-temperature and pressure testing, the performance is stable and reliable, in line with national standards and industry specifications, making it an ideal choice for industrial pipeline control.

We offer a variety of specifications and models of high-temperature and high-pressure butterfly valves to meet the needs of different diameters and pressure levels. The product undergoes strict quality inspection before leaving the factory to ensure that every valve meets the quality standards. Supporting non-standard customization, the material, connection method, and driving device can be adjusted according to specific working conditions. A professional technical team provides selection guidance and after-sales service to ensure that customers have no worries during use. Welcome to inquire about detailed technical parameters and quotations. We will provide you with high-quality valve solutions.
