·Bi-direction sealing structure increase service life;
·Metal-to-metal sealing between gate-to-seat and seat-to-body;
·Simple and reliable gate and seat design promotes ease of field service and minimal spare parts inventory;
·Seal between each seat and body assists in low pressure sealing. It also protects against intrusion of particle contaminants into body cavity and seal areas;
·Stem seal design covers full range of pressures, temperatures, and fluids encountered in wellhead and manifold service;
·Metal-to-metal seal between bonnet and body, working pressure can reach 20000psi;
·Back seated of stem to allow stem packing replacement under pressure; (To ensure safety, it is recommended to replace the packing after pressure relief)
