How do you choose a gate valve lubricant for H2S or water exposure?
Start from your service conditions (temperature, line media, H2S, water) and check each one against the lubricant’s data sheet, not its product name. For Everlast 4B the documented properties are a -20 to 400°F range, H2S inhibition, water resistance and corrosion protection; anything outside those needs confirmation from Lubchem or your valve manufacturer.
- Service temperature: stays inside -20 to 400°F, the data sheet range.
- H2S in the line: the data sheet lists “Inhibited for H2S”; confirm it against any sour-service specification your company applies.
- Water present: the data sheet lists water resistance and corrosion protection.
- Valve type: close tolerance gate valves with polished metal surfaces, where Lubchem cites high adhesion.
