Introduction
The Type 630 Big Joe™ regulators are direct-
operated, spring-loaded, pressure reducing regulators.
They are available in 1 and 2-inch / DN 25 and 50
body sizes, and they are designed for maximum inlet
pressures to 1500 psig / 103 bar and outlet pressures
from 3 to 500 psig / 0.21 to 34.5 bar. The Type 630
can be used with natural gas, air, or a variety of other
gases for such applications as fi rst-stage farm-tap
regulators or high-pressure industrial regulators.
The Type 630 can be converted in the fi eld to a
relief valve or is available as the Type 630R relief
valve/backpressure regulator; refer to the separate
Type 630R Bulletin (71.4:630R) for information.
Features
• High-Pressure Capabilities—
Inlet pressures up
to 1500 psig / 103 bar and control pressures up to
500 psig / 34.5 bar.
• Rugged Construction—
Compact, sturdy design
and solid metal construction provide a strong,
reliable, long-lasting regulator.
• Better Low-Pressure Control—
The Type 630
is available in both high-pressure and low-pressure
constructions; the low-pressure units have a larger
diaphragm area to provide more accurate control of
low-pressure settings.
• Sour Gas Service Capability—
Optional materials
are available for applications handling sour
gases. These constructions comply with
the recommendations of the NACE
International MR0175.
