Cage structure of the valve

(Sleeve valve)
1 easy installation and maintenance. Seat cover to squeeze through the valve on the valve body, with screw connection, installation and maintenance.
Change the flow characteristics of convenience. The sleeve valve in fluid flow outwardly from the sleeve, referred to as the center outward flow, and vice versa, said external flow toward the center. It is external to the center of the flow through the sleeve valve structure FIG. Symmetrically distributed on the sleeve 3,4 or 6, the throttle opening, the shape of the throttle opening with the desired flow characteristics, and therefore, the sleeve can be easily replaced (shape) of the throttle opening to change the control valve flow characteristics.
Noise reduction and video port to reduce cavitation. Sleeve and spool can be opened in order to reduce the noise of the control valve, a plurality of apertures, the use of holes high temperature solenoid valve
Increase the resistance, the velocity head is converted into kinetic energy, so that the noise reduction. Typically, the sleeve valve can reduce noise above 10dB, therefore, the noise reduction required Occasion been widely applied. Can also be used to reduce control valve noise, multi-stage step-down method, such as multi-stage spool and sleeve structure. Be assigned to the control of the total pressure drop across the valve at all levels, at all levels will not cause the fluid steam and air, so that the control valve noise reduction, and to weaken and prevent erosion caused by steam and air and wear. The bottom of the sleeve valve spool plane, such as cavitation bubble burst the impact is not applied to the spool, and media self-absorption, the sleeve valve cavitation impact, long service life.two position three way valve
Leakage compared to the single-seat valve, the graphite piston seal between the sleeve and the spool, long-running, the wear of the seal ring of the sleeve valve leakage than the single-seat valve pneumatic auto drain
5 interchangeability and versatility. Switch to a different sleeve, available different flow coefficients and different flow characteristics.
Reduce the unbalanced force is affected. Typically, the sleeve valve spool open balance hole of the spool unbalanced force suffered greatly reduced, at the same time, it has a damping effect on the control valve stability to work. Therefore, this type of control valves commonly used in differential pressure applications require low noise.flange solenoid valve
