Introduction

The 167D Series switching valves are typically used

to deliver constant reduced pressure of gaseous

ﬂ uids to pilot-operated controllers and other

pneumatic instrumentation.

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

switching valves.

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

switching valves.

Features

•

Compact—The Types 167D and 167DA

switching valves are engineered for outstanding

performance in a compact, lightweight package.

• Easy, Accurate Adjustment

—

With a choice of

springs for optimum resolution, the switching point

is set to a speci c requirement by an adjusting

screw atop the spring case.

• Sour Gas Service Capability—NACE MR0175

and MR0103 compliant construction available.

• Optional Stainless Steel Construction—

The Types 167DS and 167DAS provide high

resistance to corrosion especially bene cial for

offshore applications.

• Ease of Maintenance—No special tools are

required to perform maintenance, and

all maintenance can be performed with the

valve in the line.

• Rugged Construction—The Types 167D and

167DA switching valves are engineered for longer

service life with minimal maintenance requirements.

• Corrosion Resistant Fasteners—Bolting and

adjusting screw are double zinc-chromated for

enhanced corrosion resistance. Optional stainless

steel bolting and adjusting screw are also available.
