Series 500 ValvesControl ApplicationsRemote Control & Check ValvesEL - Solenoid Controlled ValveA 3-way solenoid valve, activated by an electric current or an electric pulse,opens or closes the main valve. The standard valve is “normally close”. The“normally open” is optional.Electric activation can be added to other control applications on request.ELCV - Hydraulic Check ValveThe valve is in the “open” position when the upstream pressure is higher thanthe downstream pressure.Should the upstream pressure drop below the downstream pressure, thevalve will instantly close, preventing return flow.Opening and closing speeds are adjustable.CVRC - Hydraulic Remote Control ValveA hydraulic relay opens or closes the valve, in response to a pressurecommand, carried by a control tube from a remote control center.Pressure Reducing ValvesPR - Pressure Reducing ValveThe valve maintains a preset downstream pressure, regardless of upstreampressure or flow rate fluctuation.The main valve is controlled by either a 3-way pilot valve (allowing full openingwhen downstream pressure drops below the set-point), or by a 2-way pilotvalve (creating minimal pressure differential in open position).PRPR/EL - Electrically Operated Pressure ReducingValveThe valve is a Pressure Reducing Valve which maintains a preset downstreampressure, regardless of upstream pressure or flow rate fluctuation.The valve’s opening is controlled by an electric solenoid valve. This eithercauses the valve to open (and regulate) or to close.PR/EL6Edition 10/2012

Control ApplicationsSeries 500 ValvesPressure Sustaining & Relief ValvesPS - Pressure Sustaining ValvePS(R) - Pressure Relief ValveThe valve maintains upstream pressure, regardless of flow rate variations.The valve will be in the “closed” position if the upstream pressure dropsbelow the set-point and will be “fully-opened” when the upstream pressureexceeds the set-point.PS PS(R)DI - Pressure Differential Sustaining ValveThe valve maintains a preset pressure differential between the upstreamand downstream pressures. The valve controls booster pumps discharge,heating and cooling systems, bypass configurations and more.QR - Quick-Relief Safety ValveThe valve opens instantly when the pressure in the pipeline exceeds the safelevel, thus relieving excessive pressure from the network. When the pressurereturns to normal, the valve closes slowly, at an adjustable pace.QRFlow Rate Control ValvesFR - Flow Rate Control ValveThe valve limits the flow rate in the network to a preset value, regardless ofpressure variations.The valve opens fully when the flow rate drops below the set-point.FE - Excessive Flow Shut-Off ValveThe valve closes when the flow rate exceeds the normal value (dueto pipeline rupture for example). Reopening is by manual reset only.FE FR7Edition 10/2012

Series 500 ValvesControl ApplicationsLevel Control ValvesFL - Modulating Float Controlled ValveThe main valve is controlled by a float valve, located in the tank or reservoirand set at the required maximum water level. The valve maintains themaximum level continuously.Optional Addition: Surge-Preventing Closure (SA).FLFLDI - Differential Float Controlled ValveA Float valve (model 70-550) controls the main valve, closing it whenthe water reaches maximum level, and opening it when the waterdrops to its preset minimum level. The differential between themaximum and the minimum levels is adjustable, at a wide range.Optional Addition: Surge-Preventing Closure (SP).FLDIFLEL - Electric Float-Controlled ValveAn automatic, level control valve, activated by an electric float that operatesthe main valve by a solenoid.Enabling adjustable differential of the max / min levels.Optional addition: surge-preventing closure (SP)FLELAL - Altitude Control ValveThe main valve is controlled by a highly sensitive pilot, located outside thetank. The pilot opens or closes the valve in response to the static pressure ofthe water. The pilot allows for differential adjustments between the maximumand minimum level.Optional Addition: Surge-Preventing Closure (SP).ALSpecial Control ApplicationsSP - Surge-Preventing ClosureThe device automatically adjusts the closing speed of a valve that is locatedat the end of a long pipeline, preventing pressure surges.Please consult DOROT, or your local distributor for details.8Edition 10/2012
