TongBall floating valve balls (hardened metal/advanced ceramic), ensures reliable closure from cryogenic to medium-temperature operating conditions. Professional grinding and polishing guarantee high spherical accuracy and excellent surface finish, achieving uniform sealing force, low operating torque and longer valve seat life. Suitable for water, steam, oil, gas and weakly corrosive media.
