small leakage; good plug stability; not easy to generate vibration
RV ZRSP(M) electric single-seat control valve has the advantage of small leakage; However, its umbalanced force is larger; Therefore, the working pressure difference is not suitable to be over high. As a balanced valve plug structure is adopted by an electric sleeve control valve, the unbalanced thrust acted on a valve stem is less, the allowalbe using pressure difference is bigger. Under the same work conditions, compared with the single-seat control valve, the sleeve valve has better plug stability, and is not easy to generate vibrationl; When the using temperature is changed, the leakage volume of the sleeve valve is not significantly different from that during normal temperature.
