A esfera e o assento da válvula da liga de cobalto cromo são partes muito importantes da bomba de poço de petróleo, sempre aparecem juntos e cooperam muito bem, nenhum material melhor pode substituí-los agora.
As esferas da válvula são feitas de liga de cobalto cromo 20 e a sede de liga de cobalto cromo é de liga de cobalto cromo 3. Eles são uma boa equipe para resistir ao problema de desgaste e corrosão no processo de proxenetização de petróleo e gás.
