ysiq (d) 30 series intelligent sleeve control valve is a pressure balance type regulating valve. sleeve-guided balanced valve core, double-line hard-sealed structure, compact structure, streamlined s streamline, suitable for a variety of high temperature, high pressure difference, low noise occasions to meet the user’s requirements.
the actuator adopts the zm10 multi-spring high-strength reinforced actuator. through simple operation, the positive and negative reaction modes can be freely replaced on the site. the micro-positive pressure protection can effectively protect the spring and the diaphragm against corrosion, thus prolonging the execution. the service life of the mechanism facilitates the use of the user. the actuator and the intelligent valve positioner are designed without a pipe connection, which improves the anti-seismic performance, the use stability, and the adjustment accuracy of the regulating valve, and satisfies the precise adjustment of working conditions.
