KHSC electric sleeve control valve is suitable for occasions where high pressure difference is prone to flash vaporization and cavitation. It is a high-performance single-seat control valve. The solid sleeve protects the valve body from valve vaporization and cavitation. The valve has a compact structure and has an S streamlined channel, which makes it small in pressure drop loss, large in flow, and wide in adjustable range. The spool has a large guiding area and good vibration resistance. The leakage of the regulating valve complies with the ANSI B16.104 standard. The regulating valve is equipped with a multi-spring diaphragm actuator, which has a compact structure and a large output force
