2 This valve is operated by the pressure of the pipeline and is used for various control applications in water supply, fire fighting, industrial, sewage and irrigation only moving component is a reinforced diaphragm, which:a. Drip tight seals the liquid passage in the closed valveb. Allows free passage in the fully open valve with minimal obstruction to the flow linec. Throttles the flow passage in the modulating valve, as dictated by the pressure in the control chamberThe valve can be closed or modulated using the line pressure or an external separate pressure source that is equal or higherthan the line S-100 Valves are made for easy, inline maintenance, executed also by unskilled personal using basic are no shafts, bearings or seals that may corrode and there is no wear and tear by dirty abrasive water or and benefitsStructural simplicity Superb design featuring exceptionally low pressure losses at high flow ratesCan be used for regulating from no-flow to maximal flow with no need for additional throttling devices or by-pass valvesFor natural liquids, sea water and industrial effluents A wide selection of materials.

3 Coating and diaphragm types All valve models fit a wide variety of control applications using Dorot pilot valvesSeries 100 Valves General5 Principle of operation3-way control systemThe main valve is controlled by a manually, electrically or pressure actuated selector that: 1 Introduces the upstream pressure or an external pressure source to the valve s control chamber, thus pressing the valve diaphragm from top to a closed position. 2 Openes the valve by relieving the pressure from the control chamber and enabling the internal pressure in the line to push the valve diaphragm up and creating an unrestricted, full flow passage. 3 Shutes all passages to and from the control chamber, thus keeping the main valve in a fixed position. This position does not exist in devices used for ON/OFF control applications but is necessary in modulating control systemA control system that consist of two restrictions:a.

4 A fixed restriction at the upstream side of the control system (nozzle or needle valve)b. ON/OFF device (valve, relay or solenoid) or a modulating pilot valve with a larger passage than restriction a that is installed at the downstream side of the control system. The main valve position is affected by the downstream pilot valve b in the following ways: 1 When the pilot valve is closed, no water can be vented to the downstream and the main valve is closed by the upstream pressure, introduced into the valve control chamber through the restriction a . 2 Opening the valve is enabled when the pilot b is fully open and allows the drainage of pressure in the control chamber to the down stream. At this position the pressure in the control chamber nearly equals that of the downstream. 3 Throttling pilot valve b so the flow running through it equals the flow entering through the restriction a , keeps a fixed volume of water in the control chamber and the main valve in a fixed 100 ValvesTechnical Data 6 Available ModelsPatternType444553478777828453A9167 94 ConnectionThreadedThreadedVictaulic FlangedFlangedFlangedFlangedThreadedVict aulic ThreadedFlangedThreadedMaterialCast IronBronzeCast IronCast IronBronzeDuctile IronCast IronCast IronCast IronBronzeDuctile Iron Ductile IronMax.
