J48 LOW PRESSURE REGULATOR

2 1/2"-6"

The J48 is a highly versatile proven range of Industrial Low Pressure Regulators, suitable for a wide range of pressure reduction applications. The J48 is available in sizes from 1/2" to 6".

The J48 is a service and appliance regulator suitable for a wide range of domestic, commercial and industrial applications. All units are designed for natural, liquid petroleum and manufactured gases. The J48 can be installed in both horizontal and vertical pipelines, with certain sizes available with angled connections for meter services applications.

PRESSURE

Maximum Inlet Pressure: 350mb(5 psig)

Maximum Outlet Pressure: 150mb(60 wg) 2 1/2=3"

345mb(5 psig) 4"-6"

SPECIAL VERSIONS

The J48 can also be supplied in two special versions, the J48Z Zero Regulator and the J48P Proportionator. The J48Z is suitable for use where burner train design creates a negative pressure on the downstream side of the regulator and thus very low outlet pressures (-0.75 to +0.25mb) are required.

The J48P is utilized to control gas pressures in a burner train, relative to the air supply.
