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)

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

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)
