Uma válvula globo é uma válvula de movimento linear usada principalmente para iniciar, interromper e regular o fluxo de fluidos em uma tubulação. Sua estrutura interna inclui um elemento tipo disco móvel e uma sede de anel estacionária em um corpo geralmente esférico — daí o nome válvula "globo". Quando o atuador ou volante é girado, a haste move o obturador para cima ou para baixo, alterando o caminho do fluxo e proporcionando controle de estrangulamento. Este projeto oferece uma boa capacidade de fechamento e é adequado para aplicações que exigem regulagem precisa do fluxo. Devido ao caminho tortuoso do fluxo, as válvulas globo tendem a apresentar quedas de pressão maiores do que outros tipos, mas compensam com excelente precisão de controle. São frequentemente utilizadas em processamento químico, geração de energia e sistemas de petróleo e gás, onde o fluxo controlado e a vedação firme são essenciais. As válvulas globo podem lidar com diversos fluidos, incluindo vapor, água, óleo e gás, e estão disponíveis em versões de acionamento manual, pneumático ou elétrico. Sua versatilidade e operação confiável as tornam a melhor escolha para sistemas que exigem modulação ou operação frequente.
