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 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:

1/2, 3/4, 1, 1-1/4, 1-1/2, 2 inch

Body:

ANSI B16.15 Bronze 250LB Threaded (NPT), or

Temperature: +32 to 400°F (Bronze 250LB Threaded)

+32 to 500°F (316 Stainless Steel 300LB Threaded or

Buttweld)

Rangeability: 50:1

2832

Three-Way Diverting/Mixing Valve

Designed as a diverting valve with one inlet and two outlets with ANSI Class III

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 50 PSID.

Sizes:

1, 1-1/2, 2 inch

Body:

ANSI B16.15 Bronze 250LB Threaded (NPT), or

316 Stainless Steel 300LB Threaded (NPT), or 316 Stainless

Steel 300LB SCH 40 Buttweld (BWE)

Trim:

Linear, Bronze (Bronze 250LB Threaded), or 316 Stainless

Steel (316 Stainless Steel 300LB Threaded or Buttweld)

Packing:

Long-Life Multi-Stack EPDM Lip Packing (+32 to 350°F)

Guided Low-Friction TFE V-Ring, Spring Loaded (+32 to 450°F),

Adjustable Graphite Packing (+32 to 500°F)
