The needle-valve is mainly designed for the water flow regulation in a pipeline.
The needle-valve is mainly designed for the water flow regulation in a pipeline. The flow regulation happens through the axial movement of a piston, operated by a rod and crank mechanism.
The piston is positioned in the center of the body valve and steers in a chamber properly shaped in order to avoid noises and cavitations damages. This characteristic confers to the valve regular operation free from vibrations.
The water flow is guided in a annular chamber around the streamlined central body. The cross section of this chamber is continuously reducing from inlet to the throttle. This causes continuous  rises of flow speed and fall of the pressure. The geometrically ideal design, confines the cavitations bubbles in the center of the outlet mouth, avoiding damages to the valve.

M-Type automatic control valves are part of La TIS Service products range for water supplies, irrigation and fire protection.
Automatic control valves, as described by EN 1074-5: “have the integral capability to control the function using energy from the conveyed water by adjusting the position of the obturator. They can be directly operated, i.e. the force is applied (via a spring or diaphragm) directly to the obturator. They can be pilot operated, i.e. the force is applied through an adjustable pilot valve”.
