Fisher Gas Regulator 630 Model

Introduction

Fisher Gas Regulator 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 first-stage farm-tap regulators or high-pressure industrial regulators. The Type 630 can be converted in the field 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—Fisher 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.

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 flow through the regulator body must be in the direction indicated by the flow 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 specified in Tables1 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.
