on all sizes, completely eliminating the need for a
special low flow device (throttling plug) or a low flow
bypass valve, while ensuring very low head loss in
“fully open” position.
A standard valve model, fit for all control operations.
A specific pilot(s) provides the required application.
The flange (face-to-face) dimensions suit ISO
Standards. This allows for quick and easy
replacement of old equipment, without the need for
additional pipeline modifications.
The valve has an internal floating shaft, allowing for
no friction or leakage, eliminating the need for shaft
sealing. The unique design of the shaft provides for
easy field maintenance.
The valve has a resilient seal disc, guided by an
almost frictionless centering device.
The valve’s body is made of Ductile Iron, withstanding
both high hydraulic and mechanical stresses.

operation in sensitive regulation conditions. When
required, conversion from a single to a double
chambered valve is easily accomplished through the
insertion of Dorot’s innovative separation disc, without
the need to remove the valve from the pipeline during
the conversion.
The valve is supplied with a replaceable seat, made
of SST, which maintains excellent durability against
erosion and ensuring a drip-tight seal.
During the closing procedure, the pace slows down,
preventing any damage that may occur from water
slam/surge.
The series includes, as an optional feature, a valve
position indicator, attached by a floating connection
(ball & socket), resulting in smooth movement, with no
wear or tear on the indicator seal.

Basic Valve Operating Modes
On-Off Mode
Standard (Single Chamber) Valve
Double Chamber Valve (Version D)
Closed Mode: The control pressure (taken from the
pipeline) is applied by the control device to the control
chamber (top of the diaphragm). The pipeline pressure
pushes the seal to open, and the control chamber
pressure forces the diaphragm to close. Since the
diaphragm area is larger than the seal area, it has
greater hydraulic force so the valve remains in the
closed position.
The double chamber version is created by inserting a
separation disc between the diaphragm and the seal.
This assembly creates a second control chamber below
the diaphragm, permitting for the activation of the valve in
low-pressure systems and enabling the activation faster
valve response. The response to varying conditions is
quick, since closure downward movement is not resisted
by pressure below the diaphragm. The closure pace of
the double chambered valve tends to slow toward the end
of the closure procedure. This feature reduce the danger
of pressure surges in short pipelines.
Closed Mode
Closed Mode: The control pressure (taken from the
pipeline or from supplementary pressure source) is
applied to the top of the external diaphragm. The bottom
control chamber drains. The pipeline pressure pushes
the seal to open, but since the diaphragm area is larger
than the seal area it creates greater hydraulic force and
which forces the valve to close thus the valve closes. At
this stage, the bottom chamber should be drained.
Closed Mode
Open Mode: The control device relieves the pressure
from the control chamber. The pipeline pressure forces
the seal to the “open” position so that the fluid can

While the valve is open, outlet
pressure is applied to the lower side of the diaphragm,

so the water stream enters the cylinder from its external
side and emerges through the internal side. The energy
is dissipated by the high-velocity, turbulent flow through
the exposed holes above the seat (due to varying trim

The pressure recovery, that is the cause of cavitation
damage, happens now inside the cylinder and not
adjacent to the body wall. As the SST material is highlyresistant to cavitation- it is not damaged.

ENGINEERING DATA
2-Way Control Device
The 2-way control device is assembled on a control
circuit, connecting upstream to downstream through the
control chamber.
There are two restrictors assembled in this circuit:
(a) A nozzle or a needle valve, at a fixed opening.
(b) A modulating device (pilot), whose passage may vary
from complete closure (b=o) to a fully open size
(when b>a).
The volume of the control media in the chamber is
determined by the relative passages (a) and (b), or, in
fact, by the opening of (b), as (a) is fixed.
Regulating Mode: The pilot is set to the required
downstream pressure. The pilot senses when the
downstream pressure reaches the required value
causing passage (b) to equal passage (a) b=a. Now,
water that flows through the control loop passes from (a)
through (b) and into the downstream. The control media
in the upper part of the control chamber is now steady,
keeping the diaphragm and seal in a fixed position. Any
change in the downstream pressure will change the
b=a balance. This change adds or drains water from the
control chamber, thus opening or closing the main valve
until it reaches the balanced regulating position b=a
once again.
Closed Mode: Pilot (b) senses a downstream pressure
higher than the set-point and closes passage (b).
Through passage (a) the upstream water flows directly
into the upper part of the control chamber, forcing the
diaphragm to close the valve.
Regulating Valve
Regulating Valve
Closed Valve
Closed Mode
Open Mode: Pilot (b) senses a downstream pressure
lower than the set-point, and fully opens passage (b),
larger than (a). All the water from the upstream flows
through (a) and (b), directly to the downstream, allowing
water from the upper part of the control chamber to
partially drain until the pressure in the chamber equals
the downstream pressure.
Pressure in the upper part of the control chamber is
decreased and the upstream water pressure forces the
seal disc to rise Closed

The 2-way control device provides sensitive, accurate,
and constant modulating, control of the main valve. The
main valve does not fully open, as the control device
prevents total draining of the control chamber.
The 2-way control device is standard in most pressure
regulating valves.

Cavitation Chart
Limits of operating conditions
The chart above sets the safe limits for valves that are supposed to operate at a considerable pressure differential.
Such conditions generate noise and possible cavitation damages to the valve body.
How to use the chart:
i. Determine the maximal dynamic pressure that may be applied in the inlet of the valve.
ii. Draw an horizontal line from the pressure scale at the left side of the chart
iii. Find the requested outlet pressure in the pressure scale at the bottom of the chart.
iv. Draw an upward line at this point.
v. The intersection of the two lines defines the cavitation characteristics of the valve operation.
- In the case that it falls in the RED zone (case I)- the valve may be damaged in a fairly short time.
- In the case that it falls in the YELLOW zone (case II)- the valve may generate a noise that exceeds 80db.
- In the case that the intersection is within the GREEN zone (case III)- the valve will perform safely and quietly
General remark: The cavitation and noise data are based on tests done by the Utah State University, US, and Delft Hydraulic Laboratories, Holland.

FIRE FIGHTING APPLICATIONS
The Dorot 300 series valves are UL-listed to be used in Fire
Protection Systems at various ranges of applications.
The Dorot UL Deluge Valves are suitable for systems that include Electric,
Hydraulic or Pneumatic detections. The Dorot 300 series Deluge Valves
are activated by each signal or by combinations thereof. All applications are
equipped with a manual emergency actuation valve and approved for use in
Fire Protection Systems as Automatic Reset or Manual Reset Valves.
DE/EL
Deluge Valves
The Dorot 300 Series Monitor Valves are designed to open immediately
as a response to Electric, Hydraulic, Pneumatic or manual activation. The
valves use the line pressure to develop maximum power and do not need
any external source of power.
The Dorot 300 Series Monitor Valves are designed to be activated locally or
remotely.
U-DE/EL
Monitor Valves
The Dorot 300 Series UL Pressure Reducing Valves are hydraulically selfoperating Diaphragm Valves that reduce High upstream pressure to Lower
downstream pressure regardless of the upstream pressure fluctuation or
unstable flow demand.
The Dorot 300 Series UL Pressure Reducing Valves are designed to
maintain constant downstream pressure at all flow conditions.
PR/UL
Pressure Reducing Valves
The Dorot 300 Series UL Pressure Relief Valves are designed to maintain
constant pressure in the fire Protection System and prevent over
pressure by relieving excess pressure back to the reservoir or vent to the
atmosphere.
