Introduction

nnnn

The 167D Series switching valves are typically used

nnnn

to deliver constant reduced pressure of gaseous

nnnn

fluids to pilot-operated controllers and other

nnnn

pneumatic instrumentation.

nnnn

• The Types 167D and 167DS are two-way

nnnn

switching valves.

nnnn

• The Types 167DA and 167DAS are three-way

nnnn

switching valves.

nnnn

Features

nnnn

• Compact—The Types 167D and 167DA

nnnn

switching valves are engineered for outstanding

nnnn

performance in a compact, lightweight package.

nnnn

• Easy, Accurate Adjustment—With a choice of

nnnn

springs for optimum resolution, the switching point

nnnn

is set to a specific requirement by an adjusting

nnnn

screw atop the spring case.

nnnn

• Sour Gas Service Capability—NACE MR0175

nnnn

and MR0103 compliant construction available.

nnnn

• Optional Stainless Steel Construction—

nnnn

The Types 167DS and 167DAS provide high

nnnn

resistance to corrosion especially beneficial for

nnnn

offshore applications.

nnnn

• Ease of Maintenance—No special tools are

nnnn

required to perform maintenance, and

nnnn

all maintenance can be performed with the

nnnn

valve in the line.

nnnn

• Rugged Construction—The Types 167D and

nnnn

167DA switching valves are engineered for longer

nnnn

service life with minimal maintenance requirements.

nnnn

• Corrosion Resistant Fasteners—Bolting and

nnnn

adjusting screw are double zinc-chromated for

nnnn

enhanced corrosion resistance. Optional stainless

nnnn

steel bolting and adjusting screw are also available.
