Daniel™ 700 Series Pilot Operated Control Valves
Datasheet
Precise Flow Control of Petroleum
Products
Whether your application is pipeline control or blending,
flow rate or pump control, Daniel has the control valve you
need.
All Daniel 700 Series control valves are self-contained and
externally pilot-operated, so one basic valve can perform
many different functions. Multiple pilot arrangements, easily
modified, allow you to choose or change valve capability as
required.
Unique design features and unit-built construction assures
positive sealing, linear valve action, uniform fast response
and leak-proof performance. In addition, the basic valves
body and internals are the same throughout the line,
simplifying spare parts inventory and reducing costs.
Each 700 Series model is designed for general control
applications using an external pilot for multiple control
functions. These valves can be installed in a horizontal or
a vertical line with flow direction vertical up.
Features and Benefits
Balanced piston principle, spring biased
Adjustable closing speed control prevents damage to
shock pressures
Linear valve action - rectangular ports provide smooth
linear action with maximum flow and minimum
pressure drop
Uniform speed of response - uniform area above main
piston provides uniform opening and closing speed
with fast rate of response
Positive (pressure type sealing) O-ring seal and valve
seats are not affected by fluid viscosity or pressure
drop
High capacity 45° (in-line) valve body assures high
capacity at low pressure drop
Sensitive regulation - pressure from 10 to 1440 psi
(69 - 9928 kPa) can be controlled within ±2 psi of set
point (± 13.8 kPa)
Large internal pilot valve ports
Zero leakage - contoured edge of piston provides
a tight seal and assures drip-tight operation and
dead-end service
Unit-built construction - all internal parts, including
seat ring, can be removed as a unit without disturbing
valve body and connections
Simple design - no diaphragms or stuffing boxes
Inherent design of valve makes it an automatic check
valve - no reverse flow

Daniel Control Valves
Model 710 / 711 On - Off Solenoid Operated
Control Valves
Typical Installation
The Model 710 valves are typically used to stop flow on
applications such as high level shut-off into storage,
on-off line block control, jet fuel filter-separator control
from a water detector, blend line selection and many
other applications requiring remote on-off control.
The Model 710 closes upon loss of electrical power while
the Model 711 opens upon loss of electrical power.
The Model 710, (normally closed), and Model 711,
(normally open), solenoid operated control valves are
designed for remote on-off control of flow. They are
externally piped with a needle valve (speed of response
control) and a strainer as standard equipment. Manual
override is a standard feature of the Model 710.

Model 750 Pressure Reducing Control Valves
Typical Installation
The Model 750 pressure reducing valve is designed to
regulate downstream pressure within ±2 psi (13.8 kPa)
or better, regardless of variations in flow rate or upstream
pressure. The pilots are balanced, single seated valves
with large ports and are not affected by variations in
upstream pressure.
Applications
Distribution system
Meter over-pressurization protection
Pipeline delivery to storage
Pump suction pressure control (positive NPSH)

Figure 2 - This drawing illustrates the most common usage
of the pressure reducing control valve. The Model 750 externally
sensed to any point downstream, provides a sensitive control for
regulation of pressure within ±2 psi (13.8 kPa). The Model 760
back pressure control valve, acting as a relief valve, protects the
system if excessive pressure or surge occurs.

Figure 3 - Pipeline “A” normally provides all the product
for distribution unless pressure drops below a required
minimum. When this occurs the Model 750 installed in
an auxiliary line “B” and sensed to the main line “A”,
opens to maintain pressure and flow until normal main
line pressure is restored.

Figure 4 - In this application, the Model 750 pressure reducing
valve lowers main pipeline pressure to a level that is within the
acceptable rating of the metering equipment. The pressure
reducing valve will control a maximum reduced pressure drop
of 1,000 psi = 6,895 kPa.
