VALVES
Configuration and Capacity
Customers must order their valve configuration,
starting with identifying the valve function. Refer
to Fig. 1 Valve nomenclature.
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
SV2 Series Safety Shut-off Valves
V2F, V2V
for full valve model
1" (DN25)
2" (DN50)
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
MCR37124 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
MCR37125
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 /
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
MCR37126
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.
