General Information
Series 500 Valves
Overview
The Dorot Series 500 is a unique, cost effective control valve for water-works and irrigation systems. It is designed for
superb regulation capabilities, combined with low pressure loss in the fully open position.
The experts at Dorot developed this technically-advanced product line with capabilities far beyond most other valves.
This guide will asist you in the selection of the optimal DOROT Series 500 valve.
Features
Wide body shape prevents cavitation
damage, and ensures very low noise
during operation.
Coating:
UV resistant and certified
for use in potable water
applications
Wear & corrosion resistant
SST seat
Option for SST indicator rod
Innovative diaphragm-trim
assembly guided by lowfriction top & bottom guides
LTP® (Linear Throttling
Plug) for superior low flow
regulation
Special valve design:
reduction in head-losses
Features of the 500 Series
• The
•
•
•
capability to regulate at “near zero” flow, as a
standard feature on all sizes, achieved by the LTP®
(“Linear Throttling Plug”) device, completely eliminates
the need for a low flow bypass valve, or internal
throteling device such as U-port or V-port.
The unique bottom guide together with the
hydrodynamically designed structure enable very low
head loss in the ”fully-open” position.
A standard valve model fits a wide variety of control
applications using Dorot pilot valves.
An especially short face-to-face dimension, ensures
maximal saving in installation space.
• An innovative internal trim ensures frictionless
operation, easy maintenance and high reliability.
• During closure, the pace slows down to prevent
slamming or water hammer / surges.
• The series includes a position indication rod, as an
optional feature, attached by a floating connection,
enabling smooth movement of the indicator.
• Very quiet and stable operation makes the valves
especially suitable for housing and residential
applications.
• All materials are WRAS & NSF approved for potable
water.

Series 500 Valves
Control Applications
Remote Control & Check Valves
A 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.
EL
EL - Solenoid Controlled Valve
The valve is in the “open” position when the upstream pressure is higher than
the downstream pressure.
Should the upstream pressure drop below the downstream pressure, the
valve will instantly close, preventing return flow.
Opening and closing speeds are adjustable.
CV
CV - Hydraulic Check Valve
RC - Hydraulic Remote Control Valve
A hydraulic relay opens or closes the valve, in response to a pressure
command, carried by a control tube from a remote control center.
Pressure Reducing Valves
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).
PR
PR - Pressure Reducing Valve
The valve is a Pressure Reducing Valve which maintains a preset downstream
pressure, regardless of upstream pressure or flow rate fluctuation.
The valve’s opening is controlled by an electric solenoid valve. This either
causes the valve to open (and regulate) or to close.
PR/EL
PR/EL - Electrically Operated Pressure Reducing
Valve
6
Edition 10/2012
Control Applications
Series 500 Valves
PS - Pressure Sustaining Valve
PS(R) - Pressure Relief Valve
The valve maintains upstream pressure, regardless of flow rate variations.
The valve will be in the “closed” position if the upstream pressure drops
below the set-point and will be “fully-opened” when the upstream pressure
exceeds the set-point.
PS PS(R)
Pressure Sustaining & Relief Valves
DI - Pressure Differential Sustaining Valve
QR - Quick-Relief Safety Valve
The valve opens instantly when the pressure in the pipeline exceeds the safe
level, thus relieving excessive pressure from the network. When the pressure
returns to normal, the valve closes slowly, at an adjustable pace.
QR
The valve maintains a preset pressure differential between the upstream
and downstream pressures. The valve controls booster pumps discharge,
heating and cooling systems, bypass configurations and more.
Flow Rate Control Valves
The valve limits the flow rate in the network to a preset value, regardless of
pressure variations.
The valve opens fully when the flow rate drops below the set-point.
FR
FR - Flow Rate Control Valve
The valve closes when the flow rate exceeds the normal value (due
to pipeline rupture for example). Reopening is by manual reset only.
FE
FE - Excessive Flow Shut-Off Valve
7
Edition 10/2012
Series 500 Valves
Control Applications
Level Control Valves
The main valve is controlled by a float valve, located in the tank or reservoir
and set at the required maximum water level. The valve maintains the
maximum level continuously.
Optional Addition: Surge-Preventing Closure (SA).
FL
FL - Modulating Float Controlled Valve
A Float valve (model 70-550) controls the main valve, closing it when
the water reaches maximum level, and opening it when the water
drops to its preset minimum level. The differential between the
maximum and the minimum levels is adjustable, at a wide range.
Optional Addition: Surge-Preventing Closure (SP).
FLDI
FLDI - Differential Float Controlled Valve
An automatic, level control valve, activated by an electric float that operates
the main valve by a solenoid.
Enabling adjustable differential of the max / min levels.
Optional addition: surge-preventing closure (SP)
FLEL
FLEL - Electric Float-Controlled Valve
The main valve is controlled by a highly sensitive pilot, located outside the
tank. The pilot opens or closes the valve in response to the static pressure of
the water. The pilot allows for differential adjustments between the maximum
and minimum level.
Optional Addition: Surge-Preventing Closure (SP).
AL
AL - Altitude Control Valve
Special Control Applications
SP - Surge-Preventing Closure
The device automatically adjusts the closing speed of a valve that is located
at the end of a long pipeline, preventing pressure surges.
Please consult DOROT, or your local distributor for details.
