Gear Valve – Gear Operated Ball Valve
The Application of Gear Valve – Gear Operated Ball Valve
The Rotork Gear Valve stands out in fluid control, offering precision alongside industry leaders like Barton 200AS, ITT Barton 288C, and Barton 450C. Geared for reliability and durability, these valves excel in critical applications requiring tight shut-off and precise flow control. Cameron Gear Valve is another notable player in the market. Whether in oil and gas, petrochemical, or power generation, Gear Valves provide superior performance and resilience, making them a top choice for professionals demanding excellence.
What is a Gear Valve?
The gear-operated valve is a manual valve that utilizes gears to amplify torque. It features a gear system connected to the handwheel via a short shaft, enabling direct transfer of torque from the valve operator. Through a series of gears, the torque is then multiplied, facilitating the opening of high-torque valves with ease. This mechanism simplifies the task of opening and closing fluid flow, even in frequent and demanding applications requiring high torque.
Features of Gear Operated Ball Valve
- Stem Anti-Fly Out Design: ZECO gear-operated ball valve features a stem design that prevents the stem from flying out during maintenance. This design ensures safety by avoiding damage caused by pressure within the valve.
- Metal-to-Metal Connection: The valve body and the left body of ZECO ball valve are connected with cushion seals, forming a metal-to-metal contact. This design prevents sealing leakage due to fire, high temperature, or vibration, ensuring no external leakage.
- Anti-Static Device: ZECO gear-operated ball valve is equipped with an anti-static device to prevent electrostatic discharge during valve operation. This device ensures safety by exporting electrostatic charges from the valve body, minimizing the risk of incidents.
- Fire Protection: In the event of a fire, ZECO ball valve’s fire-proof structure ensures continued operation by preventing serious leakage. By using metal seals between the ball and valve body, it prevents the expansion of fire and maintains pipeline integrity.

The Operation Theory of Gear Valve – Gear Operated Ball Valve
The operation theory of the Gear Operated Ball Valve involves using gears to multiply torque, ensuring smooth operation. In a ZECO Valve, the gear system connects to the handwheel via a short shaft, allowing direct torque transfer. This mechanism, similar to Barton 316C and Barton 224C valves, enhances torque, making it easier to open and close the valve, even in high-torque applications.
