What LibertyCES's vendor documentation shows

The seat-material ladder is the content: the same body spans -196°C to +550°C purely by changing seat construction — the widest single-family range in the corpus and directly relevant to hydrocarbon service running from cryogenic light ends to hot heavy residues. HPBV-STJ's triple-point steam jacketing (shaft/bearings, body and disc all jacketed, steam circulating through the full disc perimeter) is the anti-solidification answer for waxy/asphaltic media. Type 800's dual-component seat rated leak-tight to EN12266-1 rate A up to 300°C is specifically stated for flammable-media fire safety.
