PERFORMANCE CHARACTERISTICS
¡ñ High-quality forgings and financial processing by solid body, both inside and outside to ensure that no cracks.
¡ñ Co-based cemented carbide hardfacing valve seat, thus greatly enhancing the temperature hardness and erosion of the ability of anti-media.
¡ñ Valve using Co-Cr-W steel ball, high temperature hardness, its anti-erosion ability of media much better than ordinary needle valve.
¡ñ By forging the stem, flexibility and strength are different, the thread rolling process is located above the packing, to avoid contact with the medium light, pole position to deal with by grinding, only in close contact with the filler to ensure that the seal without outside leakage, and reducing the moment to open, flexible and comfortable when the valve gate.
¡ñ The unique design of the metal gasket in the mouth by special quenching and tempering process to ensure good high-temperature sealing pressure.
¡ñ Densification of fine indeed flexible graphite packing, security of the high temperature and high pressure without leakage.
