Key Products and Services
Worm Gearboxes
Worm Gearboxes
Heavy-duty ductile iron and stainless-steel options delivering up to 516,000 foot-pound torque for precise valve control. Designed for quarter-turn valves and damper drives, our solutions provide enhanced mechanical advantage, enabling safe and efficient manual valve operation. Offered in manual or MOV configurations, allowing operation by an individual or an electric motor. Our in-house machining capabilities allow us to provide custom mounting configurations to meet customer-specific application requirements.
Bevel Gearboxes
bevel gearboxes
Engineered for smooth operation in tight spaces where directional torque changes are critical. Our bevel gearboxes are designed for both thrust and non-thrust applications, including gate and globe valves. These gear operators are versatile for nearly any multi-turn, right-angle application where mechanical advantage is needed.
Declutchable Gearboxes
declutch gearboxes
Declutchable worm gearboxes, AKA “sandwich” style manual overrides, are mounted between the mainline valve and either a pneumatic, hydraulic, or electric actuator as part of an automated valve package. The declutch gear enables manual operation of the automated valve assembly if the facility were to lose air supply, power, gas, hydraulic fluid power, or electricity.
