Description

Service Regulators
The Types R622H, R622E and R652E regulators are designed
for high pressure (pounds per square inch) vapor service. These
regulators have high capacity internal relief valves.
When used on first stage service, the Type R622H regulator
reduces container pressure to 10 psig / 0.69 bar for a second
stage regulator. On final stage service the regulator reduces
container pressure for a high pressure burner. The regulator is
normally painted RED.
The Type R622E or R652E standard outlet pressure setting is
2 psig / 0.14 bar. The regulator is painted PALM GREEN with a
WHITE CAP. It is an intermediate stage regulator that reduces
10 psig / 0.69 bar first stage pressure to 2 psig / 0.14 bar.
They are used on 2 psig / 0.14 bar pressure systems. The
Types R622E and R652E are not suitable for first stage service.
Second Stage Low Pressure Regulators
The Types R622, R642, R652 and HSRL Series regulators
provide low pressure (inches of water column) delivery
pressures. They are normally set at 11 in. w.c. / 27 mbar
pressure. They have high capacity internal relief valve
construction. The regulators are normally painted PALM
GREEN. The units differ in construction and capacity rating.
Specifications section, Tables 1 and 2 list the specifications for these regulators. Contact the factory if the regulator is to be
used on any service other than LP-Gas, natural gas or air. The following information is located on the spring case:
Type number, orifice size, spring range and date of manufacture.
1. The pressure/temperature limits in this Instruction Manual or any applicable standard limitation should not be exceeded.
2. Product has passed Fisher
