SEAT ELASTOMERS
Buna N (nitrile) is the basic seat elastomer. It isexcellent for petroleum oil and gases, fuel oilsand alcohols from -10° F to +200°F. Hypalonis optionally offered compounded for maximumchemical resistance. Particularly suited for oxidizingacids, it resists hydrocarbon oils and fuels from-10° F to +250° F. Viton is highly resistant to mineralacids and hydrocarbons and resists moderateconcentrations of hydrogen sulphide. Serviceablefrom -10° F to +400° F (Not suitable for steam).

PLASTIC COATINGS
Internally plastic-coated valve bodies and bonnet are available on request.

TESTING
MKP Gate Valves are hydrostatically tested at assembly. Stem seal, body, and seat are inspected for zero leakage under pressure, before acceptance.
