SV2 SERIES SAFETY SHUT-OFF VALVES USER MANUAL
VALVES
Configuration and Capacity
Customers must order their valve configuration,
starting with identifying the valve function. Refer
to Fig. 1 Valve nomenclature. for full valve model
structure. Current and future available valve functions include:
• V2F = On/off
Other selectable items include voltage, capacity, port threads,
NEMA 1/IP20 or NEMA 4/IP66 with conduit connections
enclosure rating, proof of closure switch(es), intelligence level
and electronics orientation. Available features are dependent
on release schedule dates.
The valve platform is comprised of two body sizes, split up into
two capacity ranges per body.
• The 1 in. (DN25) valve body
was designed with ¾ in.
(DN20) and 1.0 in. (DN25)
inserts, designated as A and B
capacity ranges, respectively.
The ¾ in. (DN20) is a potential
future release.
• The 2 in. (DN50) valve body has 1.5 in. (DN40) and 2.0 in.
(DN50) inserts, designated as C and D capacity ranges.
In the valve model number, accessories and replacement
parts such as flanges, solenoids and filters, the AB and CD
nomenclature is consistently used to identify the applicable
valve body size / capacity.
Intelligence
There are 2 available levels of valve intelligence,
however, order availability of various models may
be limited to North America or the European Union
plus the rest of the world. As well, only certain
intelligence levels are available with certain valve
functions. The 9th digit in the valve model number signifies
the embedded intelligence level. Throughout this manual,
reference is made to the available Intelligent Features
designation as follows:
• 5 = BASIC. No Modbus or Pressure Module compatibility
(SV20).
• 6 = STANDARD. Includes Modbus, Pressure Module
compatible, external VPS using Pressure Module (SV200).
Communication
Valve models with intelligence levels of 6 have embedded
Modbus RTU communications. When connected to the
HMI or PC Tools, Modbus registers are auto-discovered so
communications are automatic. With the PC Tool, a USB
to RS-485 converter is required as an interface between
the computer and the valve. Since the Modbus RTU
communication used is an open protocol, the SV2 Series
valves may be wired to a building automation system master
directly or through a secondary port on the HMI Tool.
The building automation system master control must
be programmed to recognize the various SV2 Series
valve Modbus registers, however. Refer to the MODBUS
COMMUNICATION section of this manual for the Modbus
addressing and the HMI Tool installation instructions, 32-
00030, for wiring information. Wiring and installation for the
PC Tool may be found in document 32-00037.
Modular Electronics
The SV2 Series valve main electronics are side flexible as
well as the Pressure Modules. The electronics configuration
is ordered from the factory, but may be changed in the field
as required. Refer to the CHANGING VALVE / ELECTRONICS
ORIENTATION section of this manual for instructions on this
procedure.
ACCESSORIES
After configuring the valve model, customers may purchase
accessories such as flanges, a Pressure Module or an HMI
or PC programming tool. All of these items are ordered
separately. For a list of available accessories, refer to the
VALVE ACCESSORIES AND REPLACEMENT PARTS / Table 1
section of this manual.
Flanges
Different flange sizes are available for each of the two
valve body sizes. Each flange model follows the AB and
CD size/capacity nomenclature to easily identify which
valves they fit.
Pressure Modules
The Pressure Module is a compact device,
which can be used for multiple functions. It
may be placed in any of 4 locations on the
valve, depending on the valve model and
what functions are required. The Pressure
Module may be used for low gas pressure
limit, high gas pressure limit, VPS (valve proving sequence)
and/or leak detection. It contains embedded sensors which
relay pressure measurements to the valve main electronics
which in turn process the information for the programmed
features. The Pressure Module features are programmed via
the HMI or PC Tool programming devices. Eight different
models of Pressure Modules are available; NEMA 4/IP66 in
4 different pressure ranges and NEMA 1/IP20 in 4 different
pressure ranges. For further information on this accessory,
refer to the PRESSURE MODULE section of this manual and/
or the Pressure Modules installation instructions, document
32-00017.

Pressure Switches
Traditional C6097 pressure switches are also compatible
with the SV2 Series valves. C6097 models are SPDT and are
available in ¼ in. NPT and flange mount, auto or manual reset,
action on pressure rise or action on pressure fall with nine
(9) available pressure ranges. Flange mount C6097s may be
mounted on any of 4 locations on the valve, depending on
the valve model. C6097 pressure switches may be used for
low gas pressure limit, high gas pressure limit or VPS (valve
proving sequence) functions. Functionality may be limited
by the mounting type and mounting location. For detailed
information on the usage of this accessory with the SV2 Series
valves, refer to the C6097 PRESSURE SWITCHES section of
this manual.
HMI or PC Tools
Programming tools for
the SV2 Series valves
are available in an
HMI (human machine
interface) or in a PC
version. The HMI or PC Tools are used to program the
intelligent SV2 valve features including:
• Valve Modbus address + communication speed
• Pressure monitoring via Pressure Module
• Low gas pressure limit setting and reset type
• High gas pressure limit setting and reset type
• VPS (valve proving system) operation
• Fuel/air firing curve (Premix/V2V valves)
The HMI or PC Tools can also be used for SV2 valve
monitoring, trending, diagnostics and troubleshooting.
Troubleshooting is facilitated by on-board fault messaging
with remediation steps. Up to 8 valves may be connected to
a single HMI or PC Tool. For further information, refer to the
following documents:
• 32-00030, HMI Tool Installation Instructions
• 32-00037, PC Tool Installation Instructions

Environmental Usage Conditions:
Ambient Conditions
• The valve is only suitable for installation in enclosed rooms.
• Condensation and dew in and on the valve are not permitted.
• No icing permitted
• Avoid direct sunlight or radiation from red-hot surfaces on the valve.
• Avoid corrosive influences, e.g. salty ambient air or SO2.
• Permitted relative humidity: min 5%, max 95%.
• The valve shall only be stored/installed in enclosed rooms/buildings.
• Long-term use in the upper ambient temperature range accelerates the aging of the elastomer materials and reduces the
service life.
• This valve is not suitable for cleaning with a high-pressure cleaner and/or cleaning products.
Mechanical Conditions
• Gaseous fuel must be clean and dry in all temperature conditions and must not contain condensate.
Logistics
• Protect the valve from external forces (blows, shocks, vibration).
• The ambient conditions described in this document apply to transport.
SECURE MODBUS® COMMUNICATION
For SV2 Series valve configuration and monitoring, Modbus communication utilizing an RS-485 BUS is used.
The SV2 Series valves include a Honeywell-specific secure Modbus protocol. Standard Modbus RTU protocol is used, however,
safety-related and writable parameters are covered by a secure layer. As a result, they are only writable when accessed using a
valid user access level and an appropriate user interface, which are designed to work with the secure layer. Read only Modbus
addresses can be accessed without the Honeywell user interface or the secure Modbus layer
USER ACCESS LEVELS
A 3-level user access level framework has been implemented into the SV2 Series valves, consisting of the User, Installer and
OEM levels.
• OEM Read/write rights with the ability to assign read/write parameter groups for the OEM and Installer levels. OEM is
defined at the original provider/programmer of the valve.
• Installer Read/write rights as assigned by the OEM.
• User Read only rights via HMI/PC Tool and the ability to reset fault codes via valve display.
Valves are shipped with default OEM and Installer passwords pre-configured. These passwords have to be
changed before the valve can be used in an application without user observation.
NOTES:
• Default passwords are automatically pre-filled in the appropriate field during the initial user login.
• The OEM can choose to create the Installer main password or allow the Installer to assign it at the initial login.
• See CHAPTER 6 ACCESS LEVELS for detailed information regarding OEM/Installer password configuration, access level
assignments and password reset procedures.
Forgetting to change the default password results in persistent lockout when the secured session is terminated. This is a
security measure that avoids using a valve in unsecure mode (without proper password configuration).
Should the Installer and/or OEM main access level passwords be lost, password reset is possible, if the reset mechanisms were
enabled by the OEM. The reset mechanism will vary between the Installer and OEM levels. Note that cycling of the valve or user
interface power will not defeat this methodology.
A detailed description of the user access levels and reset mechanisms can be found in Chapter 6: Access Levels in this
document.

GAS VALVE SIZING
The procedure below along with the valve capacity curves shown in Figs. 7-12 will help to identify the correct valve size for your
application. Valve selection may also be accomplished via the SV2 Series valve configuration tool, found at
http://www.combustion.honeywell.com/SV2Series.
Honeywell gas valve capacities are shown in Figs. 7-12 in:
• Cubic feet per hour (CF/H) or cubic meters per hour (M3/H)
• For gas with a specific gravity/relative density of 0.64 (1 CF/H = 0.0283 M3/H).
• Capacities for natural gas are at ANSI Z21.21 or EN437 standard conditions of 15.6°C / 60°F and 1013.3 mbar / 406.9 in w.c.
/ 29.2 in. HG / 14.7 psi pressure
Sizing procedure:
1. Check the burner nameplate for:
a. The type of gas used.
b. The gas flow capacity. The capacity will be listed in BTU/H, KW/H or CF/H (cubic feet per hour).
2. Call the gas utility for information on:
c. The specific gravity (sp gr)/relative density.
d. BTU per cubic foot (BTU/ft3) or KW per cubic meter (KW/M3) for the type of gas used.
3. Find the burner capacity in:
e. CF/H. If the capacity is listed in BTU/H, convert to CF/H by the following formula:
• Capacity in CF/H = BTU/H (from burner nameplate) / BTU/FT3(from gas utility)
f. M3/H. If the capacity is listed in in KW/H, convert to M3/H by the following formula:
• Capacity in M3/H = KWH (from burner nameplate) / KW/M3(from gas utility)
4. For gases with specific gravities/relative densities other than 0.64, correct the burner CF/H or M3/H from step 3. by
multiplying it by the proper conversion factor found in Table 3.

LP gas (Propane) 1.530 1.66
G31 (100% C3H8) 11.550 1.67
1. Per EN437.
5. Use the corrected burner capacity in CF/H or M3/H as calculated in step 4 (if applicable) when determining the gas valve
size in Figs. 7-12.
6. Determine the available pressure drop across the valve and draw a horizontal line at this pressure in Figs. 7-12.
7. Draw a vertical line in Figs. 7-12 at the capacity (CF/H or M3/H) previously determined, using the corrected capacity for a
gas with a specific gravity other than 0.64 as calculated in step 4 above.
8. Use the flange size with the appropriate valve size shown at the intersection of the horizontal and vertical lines in Figs. 7-12.
If the intersection of the horizontal and vertical lines is close to the right-hand edge of the chart or not on the chart, you may
need to use the next higher valve size. Perform the same procedure for the next higher valve size to ensure the capacity can
be obtained with that valve at the required pressure drop.

NOTE: NEMA 4 / IP66 solenoid covers contain vents to dissipate heat build-up created by the solenoids when powered.
Vent sizing meets the requirements for preventing finger intrusion into the space. The solenoid casings themselves,
housed inside the solenoid cover, meet NEMA 4 / IP66 requirements.
