Butterfly Valve Maintenance

These valves can range from fully open to fully closed, regulating, or throttling the fluid flow in large pipes with limited space conditions. Butterfly valves are especially popular in high-performance areas like energy plant equipment and HVAC systems. However, a lack of valve maintenance can lower the downtimes or even equipment failure.

Regular maintenance of a butterfly valve includes the following:

• • Cleaning and lubrication

• • Seal and gasket replacement

• • Verification of torque required for operation.

• • Checking the hydraulic or pneumatic pressures and also electrical system associated with the actuator.

Despite regular maintenance, a butterfly valve might face sudden operational issues like leakage, sticking, binding, insufficient flow control, and excessive torque. Removing the obstruction, replacing the worn parts, correcting adjustments on parameters, as well as fixing alignment solves these problems. A savvy operator should fix the problem based on the root causes.
