ysiq(d)f30 series intelligent pilot cage single seat control valve adopts pilot valve core structure, the flow channel is s type, compact structure, good sealing effect, high cutting capacity, wide application range and long service life. can be applied to more severe working conditions, especially for large diameter high temperature and high pressure and high leakage level 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.
