When the valve is in the closed state, the seat ring on the upstream and downstream sides cuts off the fluid and the accumulated matters in the middle cavity of the body can be excreted, The excreting device features the following functions:
Can check if the seat ring leaks or gets damaged beforehand; Reduce pollution to the valve due to the medium replacement; The packing on the stem portion can be replaced when the valve is in the fully opened or closed state under the working pressure.
