1、 Electric cage type single seat regulating valve overview
Electric cage type single seat regulating valve is a pressure balance regulating valve,pick Guided by a cage sleeve and equipped with a single seat sealing structure, paired with a multi spring actuator or Electric actuator with flow channelSStreamlined design, using imported sealing rings. Overall equipment It has the characteristics of stable work, large allowable pressure difference, precise flow characteristics, and low noise. particular Do not apply to work environments that allow for small pressure differences or large pressure differences before and after the valve. This series of products includes room temperature type, high temperature type, low temperature type, and adjustable cut-off type There are various types such as corrugated pipe sealing. The nominal pressure rating of the product includesPN1.6、4.0 6.4、10.0Valve body diameter rangeDN20-DN300Applicable fluid temperature-150℃-+560℃Multiple levels within the scope; Leakage level atmosphere is divided intoⅣLevelⅤLevelⅥGrade; The flow characteristics include straight lines and equal percentages. Multiple specifications to choose from

3、 Electric cage type single seat regulating valve Valve cover form
Note: Room temperature type: Working temperature of room temperature type-20-+200℃The leakage level isⅣGrade.
High temperature valve cover with added heat sink, which can be used for medium temperature-60-+450℃The occasion.
The bellows sealing type forms a complete seal for the valve stem that moves up and down, blocking fluid leakage.
The low-temperature type adopts an extended valve cover and insulation board structure, which can be used for-196℃Deep cold occasions.
