API6A MUD GATE VALVE X-DM PAGE 79 APPLICATION • Drilling and well-treating chemicals • Sour gas and crude oil • Abrasive drilling mud • Pipelines and manifolds • Wellheads • Water, oil and gas lines • Cements and slurries • Corrosive water flood lines • Up to 5000 PSI and 400°F services SEAT ELASTOMERS Buna N (nitrile) is the basic seat elastomer. It is excellent for petroleum oil an gases, fueled oils and alcohols from -10°F to +200°F. Hypalon is optionally offered compounded for maximum chemical resistance, particularly suited for oxidizing acids, it resists hydrocarbon oils and fuels from -10°F to +250°F. Viton is highly resistant to mineral acids and hydrocarbons and resists moderate concentrations of hydrogen sulphide. Serviceable from -10F to +400°F (Not suitable for steam) PLASTIC COATINGS Internally plastic-coated valve bodies and bonnet are available on request. TESTING Mud GateValves are hydrostatically tested. Stem seal, body and seat are inspected for zero leakage under pressure, before acceptance. NOMINAL SIZE in.
