1、 Overview of Electric Sleeve Regulating Valve
Electric sleeve regulating valve is a pressure balanced regulating valve, which adopts sleeve guidance, pressure balanced double sealing surface valve core mechanism, and is equipped with multi spring pneumatic actuator or electric actuator. The flow channel isSLinear flow, with overall characteristics of work balance, large allowable pressure difference, precise flow characteristics, and low noise. Especially suitable for situations with high flow rates, large pressure differences before and after valves, and no leakage requirements. This series of products comes in various forms such as room temperature type, high temperature type, low temperature type, adjustable cutting type, corrugated pipe sealing type, etc. The nominal pressure rating of the product includesPN1.6、4.0、6.4、10.0Valve body diameter rangeDN20-500Applicable fluid temperature-196-+560℃Multiple levels within the scope. Leakage level includesⅣLevelⅤLevelⅥGrade. The flow characteristics include straight lines and equal percentage characteristics. Multiple varieties and specifications are available for selection
