1850
Three-Way Mixing Valve
This valve has two inlets and one outlet, and is the simplest solution
for mixing or bypass applications with ANSI Class IVshut-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 300 PSI. In the 1/2 through 2
inch sizes, the flow can be reversed for diverting if this port configuration is
desirable.
Sizes:
1/2, 3/4, 1, 1-1/2, 2, 2-1/2, 3, 4, 6, 8, 10, 12 inch
Body: ANSI B16.1 Iron 125LB Flange or 250LB Flange (8 thru 12)
WCB Steel or CF8M Stainless Steel 150LB Flange or
300LB Flange (1/2 thru 12)
Trim: Linear, 316 Stainless Steel
Packing: TFE V-Ring, Spring Loaded ( +32 to 450°F)
Adjustable Graphite (+32 to 500°F)
Adjustable Graphite w/Extension Bonnet (+32 to 800°F)
Temperature: +32 to 350°F (125 FLG)
+32 to 400°F (250 FLG)
+32 to 800°F (150 or 300 FLG)
Rangeability: 30:1 (sizes 1/2 thru 2)
50:1 (sizes 2-1/2 thru 12)
1852
Three-Way Diverting/Mixing Valve
Designed as a diverting valve with one inlet and two outlets with ANSI
Class II shut-off. 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, 6, 8, 10, 12 inch
Body: ANSI B16.1 Iron 125LB Flange or 250LB Flange (8 thru 12)
WCB Steel or CF8M Stainless Steel 150LB Flange or
300LB Flange (2-1/2 thru 12)
Trim: Linear, 316 Stainless Steel or Alloy 6
Packing: TFE V-Ring, Spring Loaded (+32 to 450°F)
Adjustable Graphite (+32 to 500°F)
o-Ring: Fluoraz 797 (2-1/2 thru 4)
EPR (6 thru 12)
Temperature: +32 to 150°F (125 or 250 FLG, 8 thru 12)
+32 to 500°F (150 or 300 FLG, 2-1/2 thru 4)
+32 to 150°F (150 or 300 FLG, 6 thru 12)
Rangeability: 50:1

Two-Way Single Seat Cylinder Balanced
Valve
A balanced valve that is an effective solution 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:
6, 8, 10, 12 inch (See 5843 for smaller sizes)
Body: ANSI B16.1 Iron 125LB Flange or 250LB Flange
WCB Steel or CF8M Stainless Steel 150LB Flange or
300LB Flange
Trim: EQ% or Linear, 316 Stainless Steel or Alloy 6
Packing: TFE V-Ring, Spring Loaded ( +32 to 450°F)
Adjustable Graphite ( +32 to 500°F)
o-Ring: Fluoraz 797
Temperature: +32 to 350°F (125 FLG)
+32 to 400°F (250 FLG)
+32 to 500°F (150 or 300 FLG)
Rangeability: 50:1
Flow direction is reversed when used with Cylinder Actuator Fail Closed.
