Description：

• Valve stem selection of special material, good strength, and can withstand the impact of high and low temperature cross changes;

• Combined low leakage packing, auxiliary lip sealing structure, safe and reliable;

• Surfacing cemented carbide on sealing surface to improve the erosion resistance of valve and extend the service life of valve;

• Valve stem up and down orientation, small switching torque, reliable sealing;

• Full diameter design, small flow resistance, strong flow capacity, good flow characteristics;

• Open rod transmission structure, valve switch position at a glance;

• The valve stem thread is not in contact with the medium, which reduces the corrosion of the medium to the valve stem thread;

• SS+ graphite or metal seal between valve body and valve cover, reliable seal;

• Extended valve cover with isolation plate design, effectively ensure that the bottom temperature of the packing is above 5℃;

• The operating mechanism is equipped with locking device to prevent misoperation of the valve;
