How a pilot valve works
WebPitot tubes were invented by Henri Pitot in 1732 to measure the flowing liquid or air velocity. Basically a differential pressure (d/p) flowmeter, a pitot tube measures two pressures: the static and the total impact pressure. The static pressure is the operating pressure in the pipe, duct, or the environment, upstream to the pitot tube.

A diaphragm or a piston provides the seal for the main valve seat. The operation of such a valve is indicated in Fig. 4. When the pilot valve is closed, the fluid pressure builds up on both sides of the diaphragm via a bleed orifice.
WebA pilot valve can be used to remotely control the directional control valves, cylinders, pumps, or motors. A pilot valve can be considered as a pressure reducing valve. Some … WebThe valve performs this function by sensing the static level of water in the tower. The control valve has a high-sensitivity three-way positioning pilot that diverts water to the control chamber once the top level is reached, thereby making the valve close. When water is at a low level in the tower, the pilot senses the need to open.
