Reliable Gearboxes for Valves
Diamond Gear provides crucial support to valve manufacturers, distributors, and service companies through a combination of tailored solutions and operational efficiency. With a comprehensive inventory, we can deliver rapid, in-house customization of worm, bevel, and declutch override gearboxes — each designed to meet specific valve requirements. Our expert team can also assist with sizing to ensure we deliver the correct gear operator for a particular valve application.

Why Diamond Gear Stands Out
What makes our gearboxes special? Some reasons include:
Inventory
With a large U.S. repository of gear blanks, we can immediately start work once a client places an order.
Customization
We provide custom machining for bolt patterns and stems.
Quick turnaround times
We offer faster delivery than competitors such as Road Torque and Sambo.
Options
We can deliver our products with custom paint or protective finishes.

Services To Support Your Needs
We offer comprehensive customization capabilities, providing clients with a complete solution for their unique valve automation needs.
