Limitorque WG Series Worm Gearboxes The rugged and reliable WG series worm gearboxes are constructed for manual or motorized operation. With ductile iron housings, bearingsupported shafts, and well-designed sealing, the WG stands up to the environmental challenges of weatherproof, submersible and buried service applications. Alternate input shaft assembly positions can be accomplished in the field due to the concentric housing design. The splined adapter is captive in the housing, eliminating the concerns over proper engagement of the adapter on the valve shaft. The range of spur gear reductions allows the WG to meet operating times for virtually any application. The WG series, when motorized by MX, L120 or SMB actuators, provides effective and reliable solutions for quarter-turn or multi-turn process control applications. The WG meets AWWA C504 requirements for manual operation and, when motorized, meets AWWA C542 requirements. High-quality, maintenance-free construction will provide years of dependable operation.
