Cv3000系列HLC小口径套筒单座调节阀Cv3000 serials HLC small-sizesleeve single-seated regulatingvalves概述GeneralHLC小口径套筒调节阀是一种高性能的调节阀，适用于流体压差超过3MPa的高压差场合。
坚固的阀芯导向和套筒可防止液体发生闪蒸和空化。
阀体结构紧凑，呈S流线型通道，压降损失小、流量大、可调范围广等优点，配用多弹簧式薄膜执行机构，使其结构紧凑、输出力大，广泛应用于工业过程的自动控制中。
HLC small-size sleeve regulating valves, a high-performance regulating type suitable for the applications where the high differential pressure exceeding 3 MPa, have been designed with a sturdy core guide and sleeve to prevent the liquid from occurring flash vaporization and cavitation. The product, with a compact body structure andS-shaped flow channel, features a low pressure drop loss, large flow and wide adjustable range. It’s used with multi-spring diaphragm actuators which have a compact structure and large output force, and widely used for the automatic control in the industrial processes.技术参数和性能Technical parameters and performance阀体Body阀体型式：直通单座套筒式铸造球型阀公称通径：20、25mm公称压力：ANSI 125、150、300、600JIS 10、16、20、30、40KPN1.6、4.0、6.4MPaBody type: Straight-way single-seated sleeve casting ball valvesNominal size: 20, 25 mmNominal pressure: ANSI 125, 150, 300, 600JIS 10, 16, 20, 30, 40 KPN1.6, 4.0, 6.4 MPa连接型式：法兰连接：FF、RF、RJ、LG法兰标准：JIS B2201-1984、ANSI B16.5-1981、GB/T9112～9124-2000等焊接连接,嵌接焊SW.材料：ZG230-450、ZG1Cr18Ni9Ti ZG1Cr18Ni12Mo2Ti、ZG00Cr18Ni12Mo2Ti、钛Connection: Flange: FF, RF, RJ, LGFlange standards: JIS B2201-1984, ANSI B16.5-1981, GB/T9112～9124-2000.Welding type: Scarf weld(sw)Materials: ZG230-450, ZG1Cr18Ni9Ti、ZG1Cr18Ni12Mo2Ti、ZG00Cr18Ni12Mo2Ti and titanium上阀盖：常温型（P）：-17～+230℃伸长Ⅰ型（E1）：-45～-17℃+230～+566℃伸长Ⅱ型（E2I）：-100～-45℃伸长Ⅱ型（E2W）：-196～-100℃注:工作温度不准超过各种材料的允许范围。
