Hard sealed copper core gate valve

Hard sealed copper core gate valve is an industrial valve that uses hard alloy sealing pairs and copper valve stems, suitable for high temperature, high pressure, and corrosive media environments.

The following is a detailed analysis of comprehensive market information:
Product characteristics and materials
Sealing structure: Hard alloy (such as Stellite alloy) is matched with copper core valve stem to achieve metal to metal hard sealing, with a temperature resistance of up to 425 ℃.
Valve body material: commonly ductile iron (QT450-10) or cast steel (WCB), copper core valve stem (HPb59-1) enhances corrosion resistance.
Applicable media: steam, thermal oil, chemical fluids, etc., with pressure levels covering PN10~PN25.
Price and Model
Price range:
DN15~DN50 small caliber: ¥ 16.48~¥ 348.2 (brass valve body).
DN100~DN300 large caliber: ¥ 1000~¥ 15560 (cast steel/ductile iron).
Typical model:
Z41H-16C (national standard flange connection).
Z15X-16P (internal thread soft seal copper rod gate valve).
Application scenarios
Industrial sector: High temperature steam pipelines for petrochemical and thermal power plants.
Special requirement: Explosion proof wave tight shut-off valve for civil air defense engineering (DN80 flange concealed rod type).
