                  [Valve features]

                  1. The inner cavity of the valve body is provided with a sealing ring which is resistant to erosion and corrosion.

                  2, The valve sealing, according to the needs of the cover are piled welding carbide, with high wear resistance, corrosion resistance function.

                  3, Various operating methods, such as manual, pneumatic (spring reset, double acting, hand wheel and no hand wheel), electric, hydraulic, gear and so on.

                  [Adaptive condition]
                         Discharge valve is mainly used in the bottom of the reactor, storage tank and other containers, discharging, discharging, sampling and no dead time shutoff operation. With the valve at the bottom flange welded to the bottom of tanks and other containers, thus removing the process medium is usually left in the container export. Discharge valve according to the actual needs of the situation, put the end of structural design for the flat type valve for the V type, and provides two modes to enhance and decrease the valve.
