High temperature and high pressure check valve maintenance ten measures introduced

Lubricate with grease. Grease should be compatible with high temperature and high pressure valve metal materials, rubber parts, plastic parts and working medium. When the working medium is gas, special 221 grease, for example, can be used. Apply grease to the surface of the seal installation groove, apply grease to the rubber seal, and apply grease to the sealing surface and friction surface of the valve stem.
