Zero-Failure Flow Control.

The Pequoig handwheel is designed to mount directly onto the drive nut, which protrudes from the non-geared operator housing. This results in direct handwheel-to-drive-nut engagement, eliminating intermediate gearing.

Learn about the PGW-101 Gearbox

The PGW 101 (formerly known as the GW101) is a high-performance manual, non-geared operator specifically engineered for precision flow control in the most demanding industrial and municipal environments. Designed for direct engagement and rugged, long-term durability, the PGW 101 is the industry-standard solution for sluice gates, valves, and multi-turn equipment. Unlike standard industry operators, the 101 utilizes a 4-3/4″ extended drive nut to provide superior thread engagement and drastically reduced wear cycles.

Direct Drive & Precision Bearings

The Pequoig handwheel mounts directly to the drive nut, eliminating intermediate gearing for maximum tactile response. Internally, high-capacity Steel Needle Roller Thrust Bearings with hardened races (top and bottom) ensure a verified 90% efficiency rating under full load.

Corrosion-Resistant Housing Options:

Choose the build that fits your environment without compromising strength. We offer 316 Stainless Steel (GW101SS) for maximum chemical and marine protection, or High-Strength Cast Aluminum (GW101A) for a lightweight, weather-proof, and corrosion-resistant alternative.

Extended Service Life Drive Nut

Engineered to outperform, the PGW 101 utilizes a proprietary 4-3/4-inch threaded drive nut. This provides over 50% more thread engagement than the industry standard, distributing operational loads over a larger area to drastically reduce thread wear and extend service cycles.

100% American Integrity

Every PGW 101 is 100% manufactured in the USA—from the initial castings and precision machining to final assembly. Our units provide guaranteed compliance with AIS (American Iron and Steel) and BABA (Build America, Buy America) requirements for all municipal and federal projects.

Use Cases

Engineered for Critical Infrastructure Environments

The PGW 101 series is battle-tested in the most punishing conditions, providing fail-safe operation for essential services including:

  • Wastewater Treatment Plants: Reliable sluice gate control under constant humidity.
  • Pump Stations: Direct-engagement valve actuation for critical flow management.
  • Municipal Stormwater Systems: Rugged durability designed to withstand extreme weather events.
  • Hydroelectric Power Plants & Freshwater Dams: Precision manual override for massive water control components.
Fully compliant with AWWA C560 and AWWA C540 standards for slide gates and valves.
