desirable to pipe the vent away, the vent outlet is
tapped 1/4-inch x 18 NPT.
Type Number Explanation
Type 164—Two-way regulator, diaphragm operated,
normally open valve.
Type 164A—Three-way regulator, same as above,
except a special adaptor is used to provide the third
outlet.
Installation
Thoroughly clean and blow out all pipe lines to remove
pipe scale and other foreign material. Make sure the
regulator is clean before making the installation, and
apply pipe compound to the male threads.
Type 164A regulators can be used either as two-way or
three-way valves. The bottom connection is plugged in
the first use and is open on three-way applications.
The two-way Type 164 regulator is normally open, and
pressure applied under the diaphragm closes the port.
The Type 164 should be installed so that flow goes from
port A to port C. A typical Type 164 installation is
shown in figure 2. Maximum inlet pressure for both
Types 164 and 164A is 250 psig (17,2 bar).

This valve can be installed in any position in the pipe
line. the installation should be make so that moisture
cannot enter the vent, but do not plug the vent. If
A typical installation of the Type 164A when used as a
pneumatic lockup is shown in Figure 1. The three Type
164A ports are identified as A, B, and C. Flow can go
from A to B, A to C, C to A, B to A, but not B to C or C
to B. The control line connection is identified as D and
is 1/4-inch NPT. The ports are either 1/4-inch or 1/2inch NPT, depending on customer specifications.

adjusting screw before tightening the diaphragm casing
nuts. This assures slack in the diaphragm, which is
essential to proper operation.
Ordering Parts
When corresponding with the factory, Sales Office or
Sales Representative regarding this regulator, give the
type number stamped on the body of the regulator, as
well as the spring range on the paper label attached to
spring case. When ordering parts, be sure to give
complete parts number of desired parts.
3. Only available with diaphragm head 1P9014.
Parts List
Adjustment
The regulator is set for the pressure shown on the
paper label attached to the spring case. The spring
ranges available are shown in table 1. To increase the
setting within a given spring range, loosen locknut (key
13 and turn adjusting screw (key 12) clockwise. Turn
adjusting screw counterclockwise to decrease pressure
setting. Be sure to tighten locknut after making the
pressure adjustment.
Maintenance
If necessary to inspect or replace the Type 164 disk
holder assembly (key 6), remove body plug (key 10).
This allows valve disk holder (key 6), spring (key 3),
and stem (key 7) to slide out. In the same manner, the
body plug (key 10) can be removed on a Type 164A to
replace disk holder assembly (key 6) and the inner
valve O-ring (key 5).
If the diaphragm needs replacing, loosen locknut (key
13) and back off adjusting screw (key 12). Remove
casing nuts (key 15) and lift the spring case (key 2) off
the assembly. This exposes the spring (key 4) which
can be lifted out, and the diaphragm assembly which
can also be lifted out. When reassembling, replace the
