Product details
Metal seated ball and seat is our key product. The core competence is our lapping technology. We are constantly improving the lapping process. Our original lapping machines are used to solve the problem of quality instability which is lapping by manual. The fully automatic lapping machine can obtain the minimum roughness to assure the “zero leakage”, guaranteed with alcohol test and kerosene test.
