PGW 104 Heavy-Duty Gearbox

PGW 104 Heavy-Duty Gearbox

Extreme-Torque Actuation for Large-Scale Systems

Uncompromising Power for the World's Largest Flow Control Infrastructure.

Uncompromising Power for the World's

Largest Flow Control Infrastructure.

The PGW 104 is engineered for the extreme. Built with a high-strength ductile iron housing and oversized internal gearing, it handles stems up to 3.5" in diameter. When municipal infrastructure demands maximum thrust and a domestic supply chain that won't fail, the 104 delivers the 100% American-made integrity required for critical gate and valve operation. Engineered for extreme-scale infrastructure, the 104 features a fully invertible design that simplifies dual-stem synchronization on oversized penstocks, allowing for identical stem directionality across both drive units.

Learn about the PGW-104 Gearbox

The PGW 104 is the heavy-weight champion of the Pequoig lineup. Specifically designed to accommodate large-diameter stems and massive axial loads, this unit is the go-to specification for primary intake towers and large-bore treatment facilities. Featuring a robust ductile iron construction and precision-engineered gear sets, the 104 ensures that even the most massive water control components remain manageable under manual operation.

OVERSIZED STEM ACCOMMODATION

The 104 is built for scale. With the ability to handle stems up to 3.5″ in diameter (2.875″ Max Thread OD), it provides the clearance and structural support necessary for the largest municipal and industrial gate systems in the country.

EXTREME TORQUE REDUCTION

Actuating massive penstocks requires precision leverage. The 104’s internal bevel gear set is engineered for maximum surface contact, delivering smooth, reliable torque reduction that allows a single operator to manage gates that would otherwise require motorized assistance.

DUCTILE IRON STRUCTURAL INTEGRITY

Strength is non-negotiable at this scale. The PGW 104 housing is cast from high-tensile American ductile iron, offering superior fracture toughness and impact resistance compared to standard gray iron or aluminum alternatives found in lighter-duty units.

BABA & AIS FEDERAL COMPLIANCE

Like all Pequoig products, the 104 is 100% manufactured in the USA. For large-scale projects relying on federal funding, the 104 provides a guaranteed compliance path for the most critical (and visible) components of the facility.

Use Cases
