Description W
arren Controls Series 2900 High Capacity General Purpose Globe Control V
alves
feature rugged iron bodies with
a
variety
of trim materials.
The equal per
centage plugs
in the 2-way valves and linear plugs in the 3-way valves
provide excellent modulating
control of a wide variety of
fluids.
The Series 2900 is ideally suited where value and
long life are important objectives for applications
including but not limited to: Food &
Beverage, Packaged W

The most commonly applied solution for sizes 3" and under with ANSI Class IV shut-off. Sizes:
2-1/2, 3, 4, 5, 6, 8, 10 inch
Body:
ANSI B16.1 Iron 125LB Flange or 250LB Flange
Trim:
EQ%, Bronze (2-1/2 thru 6), 300 Series Stainless Steel (2-1/2 thru 10), or 17-4 PH Hardened Stainless Steel (2-1/2 thru 6)
Packing:
Guided Low-Friction TFE V

2922
Two-W
ay Double Seat Balanced V
alve
A balanced valve that is an effective solution for sizes over 3" and for higher pressures. Its double seat design allows for dirtier fluids and requires less force to operate than unbalanced valves so smaller actuators can be used. It is limited to ANSI Class III shut-off. Sizes:
2-1/2, 3, 4, 5, 6, 8, 10 inch
Body:
ANSI B16.1 Iron 125LB Flange or 250LB Flange
Trim:
EQ%, Bronze or 300 Series Stainless Steel
Packing:
Guided Low-Friction TFE V
-Ring, Spring Loaded
Temperature:
+32 to 350°F (125 FLG) +32 to 400°F (250 FLG)
Rangeability:

Two-W
ay Cylinder Balanced V
alve
A balanced valve that is an effective solution for sizes over 3" and for higher pressures. It requires less force to operate than unbalanced valves so smaller actuators can be used. Its single seat o-ring seal design facilitates ANSI Class IV shut-off. It is limited to cleaner fluids. Sizes:
2-1/2, 3, 4, 5, 6 inch
Body:
ANSI B16.1 Iron 125LB Flange or 250LB Flange
Trim:
EQ%, Bronze, 300 Series Stainless Steel, 17-4 PH Hardened Stainless Steel, or Alloy 6.
Packing:
Guided Low-Friction TFE V

O-Ring:
EPDM (BRZ) Fluoraz 797 (300 SST
rim, 17-4 pH or Alloy 6 T
rim)
Temperature:
+32 to 300°F (BRZ) +32 to 350°F (125 FLG w/ 300 SST
rim, 17-4 PH or Alloy 6 T
rim)
+32 to 400°F (250 FLG w/ 300 SST

Three-W
ay Mixing V
alve
This valve has two inlets and one outlet, and is the simplest solution for mixing or bypass applications with ANSI Class IV shut-off. In normal applications the inlet pressures are near equal and control is possible from 5% to 95% of travel with inlet pressures up to 100 PSI. Sizes:
2-1/2, 3, 4, 5, 6, 8 inch
Body:
ANSI B16.1 Iron 125LB Flange or 250LB Flange
Trim:
Linear
, Bronze (2-1/2 thru 6) or
300 Series Stainless Steel (2-1/2 thru 8)
Packing:

2932
Three-W
ay Diverting/Mixing V
alve
Designed as a diverting valve with one inlet and two outlets with ANSI Class II shutoff. However
, flow can be reversed for mixing if this port
configuration is desirable. The difference between the upper port and lower port pressure must not exceed 50PSID. Sizes:
2-1/2, 3, 4, 5, 6, 8 inch
Body:
ANSI B16.1 Iron 125LB Flange or 250LB Flange
Trim:
