Patent ID: 7021333

Claim:
A flow control and pressure reducing valve comprising: a cage constituting a body; a lower body of the cage constituting at least two pipe legs, and having at least one inlet opening and at least one outlet opening for the fluid; means to prevent communication between the inlet and outlet openings through the lower body; an upper cylindrical cage body which has a cylindrical access opening, which opening is used to mount and to dismount inner components of the valve, where by mounting the inner partition component inside the valve body, an inlet chamber and an outlet chamber, along with a first intermediate chamber, are created therein, with said inlet chamber being in flow communication with the inlet opening of the lower valve body, and said outlet chamber being in flow communication with the outlet opening of the lower valve body; a partition means within the upper valve body, which isolates the inlet chamber from the outlet chamber; a cylindrical cavity (X) which is a second intermediate chamber around said upper cage body extending through the upper valve body, has communicative passage means, around the partition means, to allow communicative fluid flow between said first intermediate chamber and said outlet chamber; a modifiable piston flow control gate means mounted in the first intermediate chamber, and means for positioning the piston in the intermediate chamber to restrict, to an intended degree, the flow of fluid to the second intermediate chamber and to the outlet chamber of the valve; cover means to cover said access opening, and to create said cylindrical cavity X which is the second intermediate chamber.
