DESIGN DESCRIPTION
Bolted bonnet, welded bonnet, pressure sealed bonnet, fully guided one-piece solid wedge to reduce wear on seating surfaces; effective back seating design and packing mechanism to ensure a tight stem seal; Tee-head stem design to prevent the stem from becoming disengaged from the wedge while the valve is in service.
Half grooved/ recessed body-bonnet joint design to accommodate spiral wound stainless steel gasket for a tight body-bonnet sealing
Hard faced surfaces of both seating rings and the wedge to provide excellent wear resistance.
