SPRING LOADED BACK PRESSURE VALVE
1 Introduction
1.1 Purpose of this manual
This manual provides guidance to owners and personnel in the installation, operation and
maintenance of the DanielTM Series 707 Control Valve manual, DAN-20064957. It is
imperative that product owners and operation personnel read and follow the information
contained in this manual to ensure that the control valve is installed correctly and is
operating according to the design certifications and safety considerations.
1.2 Description of the 707 Backpressure Control
Valves
1.2.1 General features of the 707 control valve
The Daniel™707 Control Valve is a spring actuated pilotless valve. It uses the compression
force of pre-loaded heavy springs installed in the valve body to counter the developing
pump pressure at the upstream of the valve.
The valve comes configured with a check valve to prevent reverse flow and an adjustment
screw mechanism to adjust the spring pre-load.
The Daniel 707 Control Valves have the following characteristics:
•Modular construction: All internal parts including seat ring can be removed with the
cylinder assembly without disturbing line connections.
•Pilotless
•No diaphragms
•45° body design assures high capacity
•Positive shut-off
•O-ring plus metal-to-metal seat
1.2.2 Control valve applications
The 707 valve is designed primarily to maintain back pressure at the upstream of the valve.
It does not require a pilot control loop to operate and as such is better suited for high
viscosity and crude oil applications.
1.2.3 Operations overview of the 707 control valve
The Daniel 707 spring actuated control valve uses the force generated by the compression
of heavy springs installed on the spring side to the piston to counter the pressure on the

USER MANUAL
bottom side of the piston. The pressure at the bottom side of the piston must exceed the
spring force to unseat the piston and open the valve.
An adjustment mechanism provides a means to adjust the spring load in the back of the
piston, which adjusts the valve opening pressure within the spring’s pressure range or set
point range. The 707 springs are a nested design; this allows two springs to be combine for
3rd set point which is an extension of the first two. The designed set point ranges for the
707 springs are as follow.
707 Springs Set-point range (Psig)
Light 5 to 40
Medium 30 to 80
Combined 30 to 120
Once the operating pressure or set point is reached, the valves opens and begins to flow.
The 707 has a balanced piston design, which means that the spring force on the spring
side of the piston must be equal or greater than the pressure at the bottom side for the
valve to remain closed.
Closed position
Figure 1-1 illustrates a closed valve. The pressure at the bottom side of the piston P1 is less
than the spring force F1 plus the check line pressure the P2. The piston is kept seated and
the valve remains closed.

WARNING
EQUIPMENT HAZARD
Never use this equipment for any purpose other than its intended use.
Failure to comply may result in death, serious personal injury and/or property damage.
Table 2-2: Environmental conditions
Parameter type Description
Severe service conditions Ensure that piping or other attachments connected to the valve
are not under stress. The design of the control valve has not
been assessed for the effects of wind, earthquake loading and
severe weather conditions.
Additional severe service
conditions
The valves are designed to be used on liquid applications for
crude oil and refined products.
Corrosive service Select the material compatible with the specific processes and
atmospheric environments. Implement a periodic inspection
and maintenance program to ensure that pressure retaining
components are free from corrosion and erosion.
The valve is not designed with corrosion allowance. Inspect the
valve's metal parts periodically for corrosion and erosion, and
inspect the seals and O-rings for wear and chemical
deterioration.
Low and freezing temperatures Low specific gravities or high viscosities reduce the flow range of
the valve. Refer to Operations overview of the 707 control valve
for more information.
Populated areas For new installations, follow the guidelines for Class Locations
found in the U.S. DOT, CRF Title 49: Part 192.5
Closed, poorly ventilated areas Install the control valve in a well ventilated area, not less than
one meter (approximately three feet) from source of ignition or
source of heat which might damage the unit.
