Figure 1. Typical Panel Layouts

Introduction

The Types 670, 671, 674 and 675 panel-mounted

loading regulators (Figures 1, 2, 3 and 6) are compact,

rugged units used primarily for manually loading

pressure-balanced gas regulators and providing

manual control for diaphragm actuator control valves.

Applications include remote control of gas pressure to

burners in reneries, power plants and various process

furnaces. The Types 670 and 675 units use the

Type 67CR or 67CFR pressure regulator, the Type 671

unit uses the Type 912 pressure regulator and the

Type 674 unit uses the Type 1301F pressure regulator.

Three basic panels are available within the product

line as shown in Figures 1 and 6, each having one

pressure regulator connected to one or two gauges

or two gauges and a changeover valve. A single

gauge typically shows loading pressure to the control

valve. With two gauges, one gauge shows the loading

pressure and the other gauge can be connected to

show downstream control pressure or any other

pressure up to 300 psig / 20.7 bar. Manual backup

of pneumatic controllers can be handled with those

670 Series units having a changeover valve. With it

the operator selects either the automatic controller

output (displayed on one gauge) or the manual

loader output (displayed on the other gauge and

adjusted by the handwheel) as the signal to the

control valve actuator.
