How to adjust a water pressure reducing valve

Dorot model "PR(3w)" is an automatic, pilot controlled, pressure reducing valve, activated by the pressure of the pipeline. The valve reduces upstream pressure to a steady, predetermined downstream pressure, regardless of fluctuation of upstream pressure and flow rate. Should downstream pressure exceed the required set-point (due, for example, to a halt in pipeline flow), the valve closes drip-tight. If upstream pressure falls to the preset downstream value, and throttling is unwanted, the valve fully opens, with negligible pressure loss. The valve’s response to pressure variation is very rapid, due to its double chamber control.

The valve maintains a preset downstream pressure, regardless of upstream pressure or flow rate fluctuation. The main valve is controlled by either a 3-way pilot valve (allowing full opening when downstream pressure drops below the set-point), or by a 2-way pilot valve (creating minimal pressure differential in open position).

The condor unit helps Dorot´s customer all over the world to control remotely hydraulic valves and optimize their performance. Thanks to its advanced control algorithm, customer can monitor performance of valves and changes settings remotely.

A standard and simple single-chamber valve design, provides smooth operation.  Conversion to a double chamber is a patented option.

Dorot Series 300 Electronic Control Valve (’30-EC’) is an automatic, solenoid control valve, activated by the pressure of the pipeline. The valve controls by the versatile DOROT “ConDor” controller that enables all control functions, or combination of functions, at extreme accuracy. Can be controlled by any pulse- activating controller.

The Dorot Series 300 Duel set-point Pressure-Reducing (’30-PRM’) valve, is an automatic, pilot controlled pressure reducing valve.

The ConDor is an automatic and autonomous, all-in-one solution that enables one standard & simple control-valve to perform any control-function or combination of control-functions constant or dynamically modulating, in local and remote control. It is an integrated system combining hardware (the controller), firmware (the software in the cpu), HMI software for mobile devices, and optional server services (SkyPlatform).

The Dorot Series 300 Pressure-Reducing (’30-PR’) valve, activated by the pressure of the pipeline, The valve reduces high upstream-pressure to a steady, pre-determined and lower downstream pressure, regardless of fluctuations in upstream-pressure or rate of flow. I case the downstream-pressure exceeds the set value, the valve will close drip-tight.

Regulates at a stable mode, regardless of valve-size, down to near-zero flow. Thus, eliminating the need for a special low flow plug-design (such as ‘V-port’) or a bypass valve.

Dorot model PRM(Pu) is an automatic pilot controlled, pressure reducing valve activated by the pressure of the pipeline. The valve reduces upstream pressure to a dual set-point downstream pressure, that shifts automatically in response to changes in the upstream pressure. The upstream-pressure normally corresponds to the demand in the network, so modulating the downstream-pressure in response to that, enables reducing the pressure when the demand is low and increasing pressure when the demand is high. As the demand may change anytime, unlike timer-control, this solution will optimize the leakage-savings while assuring customer service.

Dorot model 'HyMod' is an automatic pilot controlled, flow-modulated pressure reducing valve activated by the pressure of the pipeline. The valve reduces upstream pressure to a downstream pressure that increases or decreases simultaneously with the demand flow. The pressure into the zone is continually adjusted according to the zone’s actual demand, thus compensating for the system loss. The pressure-flow profile can be adjusted The Dorot HyMod will control from no flow, to maximal full open flow without any chattering or slamming.

The valve will regulate downstream pressure to one of two set-values. The set-value is selected by an electric command sent from a PLC controller to the solenoid-valve in the control-trim of the valve. Both pressure values can be easily adjusted by the user. The electric command can be optionally overridden by a manual selector valve.
