Emerson 630 Data Sheet

Type 630 Regulator

Introduction

The Type 630 Big Joe™ regulators are direct­operated, 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rst-stagefarm-tap

regulators or high-pressure industrial regulators.

TheType630canbeconvertedinthe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.

1. The pressure/temperature limits in this Bulletin and any applicable standard or code limitation should not be exceeded.

Installation

These regulators may be installed in any position.
Some installations may require a remote vent line.
Protect all vent openings against the entrance of rain,
snow, debris, or any other foreign material that may
plug the opening.

Directionofowthroughtheregulatorbodymustbe
inthedirectionindicatedbytheowdirectionarrow

found on the regulator body.

Overpressure Protection

As is the case with most regulators, these regulators
have an outlet pressure rating that is lower than the
inlet pressure rating. Overpressure protection is
needed if the actual inlet pressure can exceed the
outlet pressure rating.

Regulatoroperationbelowthelimitsspeciedin

Tables 1 and 2 do not preclude the possibility of
damage from external sources or from debris in
the pipeline. The regulator should be inspected for
damage after any overpressure condition.

Figure 3. Type 630 Operational Schematic

Principle of Operations

Refer to Figure 2. In the regulator construction, outlet
pressure registers beneath the diaphragm. As long
as the outlet pressure is less than the set pressure,
spring force on the diaphragm causes the lever to hold
the valve open. When the outlet pressure exceeds the
set pressure, the diaphragm moves to compress the
spring and the lever closes the valve until the outlet
pressure returns to set pressure.

2. Nitrile (NBR) valve disks are normally furnished for pressure drops to 200 psi / 13.8 bar, differential. For better erosion resistance, Nylon (PA) valve disks are normally furnished for
higher

pressuredrops.Someerosionofvalvedisksoccursatallpressuredropsduetosolidparticlesintheowstream.Therateoferosionishigherwithlargeamountsofimpuritiesin

1. Damage to internal parts of the regulator may occur if outlet pressure exceeds the actual pressure setting by amounts greater than those shown in this column.

2. For outlet pressure settings to 25 psig / 1.7 bar only. For pressure settings over 25 psig / 1.7 bar, outlet pressure is limited by maximum emergency outlet pressure of 45 psig / 3.1 bar.

3. For outlet pressure settings to 350 psig / 24.1 bar only. For pressure settings over 350 psig / 24.1 bar, outlet pressure is limited by maximum emergency outlet pressure of 550 psig / 37.9 bar.

4. Leakage or bursting of pressure-containing parts may occur if outlet pressure exceeds these values.

To determine the wide-open capacity for relief sizing

withtheowcoefcients(Cg), use the appropriate

procedure below.

1. Ifowiscritical(absoluteoutletpressureis

equal to or less than one-half the absolute inlet
pressure), use the equation:

Flow = (Absolute Inlet Pressure) (Cg) (1.29)
