high-capacities in low-pressure drop systems. Typical applications include: inert gas and
plant air headers.
Pressure Reducing
Type LR125
Body Size
NPS 1, 2, 3, 4 /
DN 25, 50, 80, and 100
Outlet Pressure Range 15 to 150 psig / 1 to 10.3 bar
Maximum Inlet Pressure 300 psig / 20.7 bar
Maximum Capacity 2052 gpm / 7769 l/min
Operation Method Pilot-Operated
Body Material
WCC Steel, CF8M or
CF3M Stainless Steel
Maximum Temp Capacity 250°F / 121°C*
Bulletin No. 71.2:LR125
The Type LR125 pilot-operated, pressure reducing regulator is designed for liquid industrial/
commercial applications. The Type LR125 provides smooth operation, tight shutoff and
long life, even in dirty service. Its internally actuated metal plug eliminates disadvantages
associated with boot-style regulators, and the specially engineered flow path deflects debris,
protecting the seat from damage and erosion. The Type LR125 is used in conjunction with
a Type 95H pilot and Type 112 restrictor. An internal inlet strainer prevents large particles
from entering the main valve, limiting damage to internal parts.
Relief/Backpressure
Type LR128
Body Size
NPS 1, 2, 3, and 4 /
DN 25, 50, 80, and 100
Outlet Pressure Range 35 to 375 psig / 2.4 to 25.9 bar
Maximum Inlet Pressure 450 psig / 31.0 bar
Maximum Capacity 3368 gpm / 12,748 l/min
Operation Method Pilot-Operated
Body Material
WCC Steel, CF8M or CF3M
Stainless Steel
Maximum Temp Capacity 250°F / 121°C*

Pressure Reducing
Type 75A
Body Size
NPS 1/2, 3/4, 1, 1-1/2, 2, and
2-1/2 / DN 15, 20, 25, 40, 50,
and 65
Outlet Pressure Range
20 to 80 psig /
1.4 to 5.5 bar
Maximum Inlet Pressure 200 psig / 13.8 bar
Maximum Capacity 260 gpm / 984 l/min
Operation Method Direct-Operated
Body Material Bronze
Maximum Temp Capacity 150°F / 66°C*
Bulletin No. 71.1:75A
The 75A regulator is designed to reduce domestic or industrial water pressure, thus
protecting plumbing fixtures and meters from high pressure surges. Type 75A is self-
contained, requiring no external control line for operation. Downstream pressure is
directly registered under the diaphragm. As the downstream pressure increases, the
diaphragm force overcomes the spring compression, causes the valve disk to rise, and
reduces flow through the regulator.
* Maximum temperature limitation may vary according to body and construction materials.
