中低压差系列调节阀 Low and medium differential valve
DC1624E 双层套筒扩径型调节阀 DC1624E Double cage expansion type control valve
The basic type of DC1624E double sleeve control valve is straight-through valve body, balanced spool, sleeve-oriented control valve, which is widely used in very severe working conditions. The fluid is mainly regulated by a specially drilled sleeve, which provides full-stroke continuous guidance for the spool. The unique small hole of the double sleeve is designed as a multi-stage pressure reducing channel, which effectively controls the flow velocity and pressure distribution in the fluid channel, especially for incompressible fluids, it can effectively solve the problem of cavitation and noise caused by high pressure difference.
Except for the double sleeve, all other parts can be interchanged with the DC1624 series control valve.
