Valve for controlling a flow

A valve comprising:

• an inlet channel and an outlet channel;
• said outlet channel has an outlet port at a first end, and an aperture at a second end;
• said inlet channel has an inlet port at a first end, and a second end with an aperture, said aperture being at least part-annularly shaped, wherein said aperture of said inlet channel is concentrically or co-axially arranged surrounding said aperture of said outlet channel;
• a flow channel is arranged concentrically outside said aperture of said inlet channel, and said flow channel is in fluid communication with said outlet channel;
• said aperture of said inlet channel and said aperture of said outlet channel are separated by a seating means, and said aperture of said inlet channel and said flow channel are also separated by said seating means;
• a disc is movably arranged between a closed position abutting said seating means in which fluid communication is prevented between said aperture of said inlet channel and said flow channel and between said aperture of said inlet channel and said aperture of said outlet channel, and an open position in which said aperture of said inlet channel is in fluid communication with both said flow channel and said aperture of said outlet channel;
• wherein flow through the valve is controlled by an applied force to said disc to close the valve.
