Gate Valve API 602 Features :
- Bolted bonnet, welded bonnet, pressure sealed bonnet; fully guided one-piece solid wedge to reduce wear on seating surfaces
- Standard trim is stellite faced seat rings, 13% chrome wedge seat surfaces, and 13% chrome stem (API trim 8). Other trims available on request.
- Stems are non-rotating with surface finish to maximize packing seal for low fugitive emissions.
- Each valve is shell, seat and backseat pressure tested per industry standard API 598.
- Gland is two piece gland / gland flange design for optimal alignment and uniform packing compression.
- Half grooved/ recessed body-bonnet joint design to accommodate spiral wound stainless steel gasket for a tight body-bonnet sealing.
- Weld ends are available per ASME B16.25/B16.11 or per customer’s specification.
- Wedges are accurately guided thru the entire stroke
- Seat faces lapped for smooth finish and superior sealing.
