Abstract: The invention relates to a valve suitable for use in high-pressure environment for transmitting a treatment fluid from exterior of which is affected by a pre-charged compression gas which keeps the bellows in contracted position and a piston preventing fluid communication between the tubing and the casing through the valve body. The interior of the bellows is affected by the tubing pressure, one half of which is transmitted to the bellows through radial sensing ports, and the other half of which is transmitted to the bellows through the bottom of the piston. When the pressure inside the bellows exceeds the pre-charged pressure, the bellows expands, pulling the piston upwardly and opening fluid communication from the tubing into the casing through the valve. A controlled-size fluid outlet port allows the tubing fluid to exit into the casing.
