Lock-up system using Type 164A to close air circuit to diaphragm of main valve in case of plant air failure. Main valve will remain in position it occupied at time of supply pressure failure.

TYPE NUMBER EXPLANATION
and is 1/4 ” NPT. The ports are either 1/4” or 1/2” NPT, depending on customer specifications.
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. This valve can be installed in any position in the pipe line. The installation should be made so that moisture cannot enter the vent, but do not plug the vent. If desirable to pipe the vent away, the vent outlet is tapped 1/4 ” x18NPT. 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”
Series 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 164 should be installed so that flow goes from port ‘‘A’’ to port ‘‘C’’. A typical 164 installation is shown in Figure 2. Maximum inlet pressure for both the 164 and 164A is 250 psi. 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 the table. To increase the setting within a given spring range, loosen lock nut (Key No. 13 Figure 3) and turn adjusting screw (Key No. 12 Figure 3) clockwise. Turn adjusting screw counterclockwise to decrease pressure setting. Be sure to tighten locknut after pressure adjustment is made.

(Key No. 10) can be removed on a Type 164A to replace disc holder assembly (Key No. 6) and the inner valve ‘‘O’’ ring (Key No. 5). If the diaphragm needs replacing, loosen locknut, (Key No. 13) and back off adjusting screw (Key No. 12). Remove casing nuts (Key No. 15) and lift the spring case (Key No. 2) off the assembly. This exposes the spring (Key No. 4) which can be lifted out, and the diaphragm assembly which can also be lifted out. When reassembling, replace the adjusting screw before tightening the diaphragm casing nuts. This assures slack in the diaphragm which is essential to proper operation. ORDERING PARTS
MAINTENANCE (See Figure 3)
If necessary to inspect or replace the Type 164 disc holder assembly, (Key No. 6) remove body plug (Key No. 10). This allows valve disc holder, spring (Key No. 3) and stem (Key No. 7) to slide out. In the same manner the body plug
When corresponding with the factory or representatives regarding this regulator, give the type number stamped on the body of the regulator as well as the spring range on paper label attached to spring case. When ordering parts, be sure to give complete parts number of desired parts.
