Product Details

The basic type of DC1629L / D pilot type low-noise control valve (which can be used for steam venting) is straight through the valve body, pilot balanced valve core, low-noise or multi-stage pressure reduction, and low-noise sleeve control valve, which is applied to very severe working conditions. The fluid is mainly regulated by the sleeve of special drilling, which provides full stroke continuous guidance for the valve core. When the valve is closed, the flow closing structure relies on the unbalanced force generated by the fluid flow closing to ensure the sealing of the valve core and realize a tight cut-off. The specially designed pilot balanced valve core can open the valve with only a small thrust. The patented all-metal guide ring and metal hard seal can ensure that the leakage level of GB / T4213 can meet level V under the high-temperature condition of 566 ℃, and there is no temperature limit for actual use.

Except for the pilot valve internals, other parts can be interchanged with DC1624 series control valves.
