Full-Port, Single Chamber,
Hydraulically Operated Valve
Main Valves
Model 106-PG
Singer Model 106-PG series control valves are hydraulically operated
by introducing or releasing water from the control chamber above the
diaphragm / inner valve assembly.
The Model 106-PG is usually combined with Singer specific purpose pilots
and accessories to provide control for a wide range of functions: typically
controlling pressure, flow or level, in almost limitless combinations to suit
particular applications. Basic valve options greatly extend the range of
application. (See Main Valve Options, High-Performance, Standard Models,
and Pilots & Accessories Sections).

MATERIALS OF CONSTRUCTION for individual components
can be upgraded from ductile iron, bronze and brass to
stainless steel, for most sizes. Consult with the factory.
OXY NITRIDE STEM provides extra protection against mineral
deposits. See Main Valve Options Section.
INTERNAL DROP CHECK option provides a built-in, drop check
to mechanically prevent reverse flow. See Main Valve Options
Section.

106-PG0708.1
INTERNAL NEEDLE STEM VALVE provides
a restriction in the
pilot circuit that is proportional to valve lift. See Pilots &
Accessories Section.
EXTERNAL SPRING LIFT See Main Valve Options Section.
MODEL PGM provides a fully operational back-up system
in the event of a diaphragm or pilot failure. See High
Performance Section.
ANTI-CAVITATION TRIM - The model 106-PG-AC allows very
high pressure drops in one valve, while retaining the standard
106 valve features. See High Performance Section.
GROOVED ENDS - See Main Valve Options Section.
RECLAIM WATER - For Grey and Reclaim Water applications.
See Main Valve Options Section.
PILOTS & ACCESSORIES - Singer Valve offers a wide range of
Pilots & Accessories. See Pilots & Accessories Section.
Model 106-PG
Automatic control valves operate by introducing or exhausting water from above the diaphragm at controlled rates. A pressure
differential is required and is either inlet to outlet or inlet to atmosphere, depending on the application. Valves are sized to provide
an appropriate pressure drop for each application. Consult the factory if the application does not have a minimum 5 psi (.35 bar) to
atmosphere or 10 psi (.7 bar) differential between inlet and outlet pressure.
Singer control valves are designed for use with clean potable water. Applications for other media are possible. Consult with the
factory.
Careful consideration of the possibility of cavitation must be given. Anti-cavitation trim is available to control the cavitation, reduce
noise and prevent damage. Refer to model 106-( )-AC in High Performance Section and consult with the factory.
The Singer model 106-PG single chambered valve is the basic valve used in practically every model bearing the 106 description. The
pilot systems are designed to meet the functional and performance requirements of specific applications. Sizing is ultimately determined
by the specific application.
Main Valves
SELECTION:
SPECIFICATIONS:
Valve(s) shall be a hydraulically operated globe (angle) valve. The inner valve assembly shall be top and bottom guided by means of
easily replaceable bearing bushings. The inner valve assembly shall be the only moving part and shall be securely mounted on a 316
stainless steel stem. The stainless steel stem shall be provided with wrench flats on all valves 1 (25mm) to 8 (200mm), for ease of
assembly and maintenance.
All pressure containing components shall be constructed of ASTM A536-65/45/12 ductile iron. The flanges shall be designed to
ANSI Class 150 or Class 300 standards. Flange drilling to ANSI shall be standard however British, ISO and other drillings shall be
available upon request.
Valve(s) shall have a protective fusion bonded epoxy coating internally and externally. The protective fusion bonded epoxy coating
shall conform to the ANSI/AWWA C116/A21.16 (current version) specification.
Valve(s) 8" (200mm) and smaller shall provide smooth "frictionless" motion with actuation being achieved by the use of a flat style
EPDM diaphragm. They shall be constructed of nylon fabric bonded with synthetic rubber. The diaphragms shall not be used as a
seating surface. No lip seals or packing may be used to seal the actuator.
Valve(s) 10" (250mm) and larger shall provide smooth "frictionless" motion and maximum low flow stability with actuation being
achieved by the use of the Singer rolling diaphragm technology. The diaphragms shall not be used as a seating surface. No lip seals
or packing may be used to seal the actuator.
The valve cover shall have a separate stem cap giving access to the stem for alignment check, spring installation and ease of
assembly.
On valve(s) 1"(25mm) and larger, bonnets shall be accurately located to bodies utilizing locating pins. Locating pins shall eliminate
corrosion resulting from the use of uncoated ductile iron to ductile iron surfaces.
Valve(s) 3"(80mm) and larger shall have the 316 stainless steel seat, bolted in place, utilizing "Spiralock" thread tapping technology.
The 316 stainless steel seat ring shall be easily replaceable without special tools.
The valve(s) shall form a drip tight seal between the stationary stainless steel seat ring and the resilient disc, which has a rectangular
cross-section and is retained by clamping on three and one half sides. The resilient disc shall be constructed of Buna or EPDM for
normal service conditions.
All external fasteners shall be 18/8 stainless steel with 18/8 washers.
All repairs and maintenance shall be possible without removing the valve from the line. To facilitate easy removal and replacement
of the inner valve assembly and to reduce unnecessary wear on the guide, the stem shall be vertical when the valve is mounted in a
horizontal line.
Each valve shall be tested prior to shipment. The standard test shall include a pressure test and a full functional, operational test
when pilots and accessories are fitted to suit a particular application.
The valve(s) shall be covered by a minimum three year (3) warranty against defects in materials and workmanship. The stainless steel
seat ring shall be covered by a lifetime replacement warranty.
The valve shall be a Singer Model. Refer to other Catalog Sections for further details.
