Abstract
A fluid valve with a single shaft-sealing module is disclosed. The single shaft-sealing module allows the annular shaft sealing rings to be squeezed to slightly deform to prevent gaps being formed between the shaft and the inner surface of the valve body, and facilitates easy clean and/or replacement of the worn shaft sealing rings.
