A ratcheting setting tool can use wellbore fluid to inflate expandable seals positioned downhole in a wellbore. For example, the ratcheting setting tool can include a piston within a first chamber. The piston can move from a first position to a second position in the first chamber when a pressure is applied to the piston. The ratcheting setting tool can include a first check valve in a second chamber. The first check valve can transmit wellbore fluid from the wellbore into the second chamber. The ratcheting setting tool can include a second check valve. The second check valve can transmit the wellbore fluid in the second chamber into an inflatable valve when the piston moves from the first position to the second position. In some examples, the ratcheting setting tool may be a hydraulic ratchet.
