Cv3000系列HSC套筒单座调节阀 Cv3000 serials sleeve single-seated regulating valves 概述 General HSC套筒单座调节阀是一种高性能的单座调节阀，适用于高压差产生闪蒸空化的场合，坚固的套筒保护阀体不受闪蒸和空化的破坏。阀体流体通道呈S流线型，压降损失小、流量大、可调范围广、阀芯导向面积大，抗振性好。调节阀配用多弹簧式薄膜执行机构，结构紧凑，输出力大。 HSC sleeve single-seated and high performance regulating valves have been designed for where the flash evaporation and cavitation are present due to the high differential pressure, and have a sturdy sleeve to prevent the damage to the body by the flash evaporation and cavitation as well as a S-shaped flow channel. It features low pressure drop loss, large flow , wide adjustable range，large area of the seat guide section and excellent vibration resistance. It’s used with multi-spring diaphragm actuators which have a compact structure and large output force. 技术参数和性能 Technical parameters and performance 阀　体 BodyType: Straight way single-seated sleeve casting ball valves Nominal size: 25, 40, 50, 80, 100, 150, 200 mm Nominal pressure: ANSI 125, 150, 300, 600 JIS 10, 16, 20, 30, 40 K PN1.6, 4.0, 6.4 MPa 连接型式：法兰连接：FF、RF、RJ、LG、沟槽型、嵌入型 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：铸钢（ZG230-450）、铸不锈钢（ZG1Cr18Ni9Ti、ZG1Cr18Ni12Mo2Ti、ZG00Cr18Ni12Mo2Ti）、钛等 Connection: Flange: FF, RF, RJ, LG, groove type and inserting type Flange standards: JIS B2201-1984, ANSI B16.5-1981, GB/T9112～ 9124-2000.
