CAVITATIONThe cavitation diagram shows three operating zones of the pressure reducing valveplotted against the upstream and downstream pressures, namely :Zone C : normal duty, no cavitationZone B : medium duty, risk of cavitationZone A : heavy duty, the pressure reducing valve shows cavitation.Continuous operation in the red cavitation zone could cause rapid damage of theinternal parts.SIZINGExample 1 (cavitation)Pressure reducing valve with : Inlet pressure P1 = 14 bar- Outlet pressure P2 = 3 bar.From the cavitation diagram it can be seen that the pressure reducing valve isconstantly working in the red zone. To avoid rapid deterioration, two pressurereducing valves could be used, one connected upstream to the other. Upstream pressure reducing valve: pressure front from 14 to 6 bar (green zone). Downstream pressure reducing valve: pressure front from 6 to 3 bar (green zone).

AUTOMATIC CONTROL VALVES

Automatic self-acting control valves designed for regulating water flow in water pipelines, suchas: Waterworks, irrigation, fire-fighting, process plants, etc.The main functions performed by the valve (also valve combinations) are as follows:- Shut-off - check - reduction, stabilization of the pressure - relief, overpressure- pressure support - level control - flow control.The more advanced models are equipped with a central control unit (EU900), of AISI 303stainless steel construction, which allows the regulating action to be performed as required bysetting the flow opening and closing speeds as well as the response gradient to the deviations.The pilot devices serve for determining the type of function and the set-point of the parameterunder control. All valves are provided with visual indication of the valve plug stem position.

OPERATING PRINCIPLES

The self-acting valves of Series EU100 consist of a main two-way body of globe type Fig 1, whose flow section is controlled by a shaped plug actuated by the energy supplied by the flow under control through a diaphragm inserted between the body and cover to form the operating chamber. When a small quantity of the fluid flows through the water control circuit, this circuit places the following ports in communication with each other :

- upstream port with pressure generally higher- downstream port with pressure generally lower- port of the operating chamber with regulated intermediate pressure.

An adjustable throttle is installed at the outlet of the upstream port, and before communication with the operating chamber. The pilot device is installed at the inlet of the downstream port. When the pilot device is fully open Fig 2 it allows direct discharge of the operating fluid coming from the upstream port; this causes a drop in pressure due to the throttling and determines a low level of pressure in the operating chamber and discharge of the latter.

The valve plug is raised to full opening position, thrust by the fluidunder control. The fully closed pilot device Fig 3 causes the same high pressure present on upstream side to be present in the operating chamber (throttling with zero flow does not cause drops) and determines the fluid under control to be shut-off. When the pilot device is in intermediate position Fig 4 it allows partialdischarge of the operating fluid coming from the upstream port; this produces a proportional drop in pressure due to the throttling and determines, in the operating chamber, an intermediate level of pressure and volume. Hence the valve plug modulates the lifting of the valve plug (in opening or in closing) thus ensuring that the required levels of flow or pressure are reached.
