Abstract: The present invention relates to an axial valve with a modular concept for the regulation of fluid flow and prevention of fluid reverse flow consisting of a single-piece and two-piece outer valve body (1; 99) that can be installed within the pipeline, the outer valve body (1; 99) of which contains a coaxially situated inlet and outlet fluid flow opening; a central valve body (2) which is connected to the outer valve body (1; 99) by means of a plurality of ribs (1.1), wherein a channels (7) are situated between the outer valve body (1; 99) and the central valve body (2), and said channels allow for an undisturbed flow of the flow fluid when said axial valve is open; an actuator (4a; 4-b; 4c; 4-SC; 4-SH; 4-SFMO) located axially within the central valve body (2; 100), the actuator of which contains an actuator piston (5-a; 5-b; 5-c; 90; 112; 106-SH) and an actuator piston rod (5.1-a; 5.1-b; 5.1-c; 86.1-a; 106.

Abstract: The present invention applies to the hydraulic axial piston regulating valve with a linear position sensor, consisting of the valve body (1) and the central part (2), around which the fluid flows when the valve is opened, the hydraulic cylinder (3) with the piston (4) and the piston rod (5), to which the valve regulating piston (12) is firmly fastened. The linear position sensor (8) is placed inside the hydraulic cylinder, and in the electric version of the valve, the sensor with the magnetostrictive waveguide (20) is used. The present invention applies also to the utilization of the linear response of such valves for the regulation purpose using various driving aids; as e.g. electro-hydraulic drive, pneumatic drive or autonomous drive using the energy of the fluid flowing in the pipeline.
