Butterfly valves are essential for reliable flow control across countless industries—but wear, corrosion, and actuator issues can reduce efficiency or cause critical failures.
At ValveRepair.com, we offer specialist butterfly valve repair services that restore your equipment to full working condition without the cost of full replacement. From wafer and lugged designs to double flanged and lined butterfly valves, we have the experience and resources to deliver a complete solution.
BUTTERFLY VALVE REPAIR
What Is a Butterfly Valve?
A butterfly valve is a quarter-turn flow control device used to regulate or isolate fluid within a pipeline. It features a circular disc mounted on a rotating shaft—when the valve is open, the disc turns to allow flow; when closed, the disc rotates to block the passage. Known for their compact design and quick operation, butterfly valves are widely used across industrial, water, chemical, and HVAC systems.
Available in wafer, lugged, flanged, and lined designs, butterfly valves can handle a broad range of pressures and temperatures depending on the materials used. They are ideal for large-diameter applications and are often chosen for their cost-effectiveness, low weight, and ease of installation. Actuated versions—either electric or pneumatic—enable automated flow control for more complex systems.
HOW WE REPAIR BUTTERFLY VALVES?
Our butterfly valve repair process is designed to restore full functionality, improve performance, and extend the service life of your valve. It begins with a thorough inspection and diagnostic report to identify issues such as worn seats, damaged discs, corroded shafts, or actuator faults. Once the problem is identified, we disassemble the valve and clean all components to remove scale, debris, and corrosion.
Critical parts like the disc, seat, seals, and shaft bushings are then repaired or replaced using OEM or high-quality compatible parts. For actuated valves, we inspect and service the actuator—whether electric or pneumatic—ensuring proper alignment and response. We also carry out surface refinishing or lapping where necessary to improve sealing performance.
Once reassembled, every butterfly valve undergoes hydrostatic or pneumatic pressure testing to ensure it meets industry performance standards. A full test certificate and condition report are provided with every completed butterfly valve repair, giving you peace of mind that your valve is ready to return to service safely and reliably.

Butterfly Valve Inspection & Diagnostic Reporting
SERVICES INCLUDE
We begin every repair with a detailed inspection, identifying wear, corrosion, or mechanical faults. Our diagnostic report outlines the valve's condition and recommends the most effective repair strategy.
Body Cleaning & Surface Finishing
We thoroughly clean the valve body, removing build-up, rust, and contaminants. Surface finishing ensures smooth operation and enhances sealing surfaces for long-term reliability.
Disc, Seat & Seal Replacement
Worn or damaged discs, seats, and seals can lead to leaks and performance loss. We replace these components with precision-fit parts to restore tight shut-off and smooth operation.
Drive Shaft & Bushing Replacement
A seized or worn drive shaft can restrict movement. We replace faulty shafts and bushings to restore smooth quarter-turn control and eliminate mechanical resistance.
Actuator Removal, Repair & Reassembly
If your butterfly valve is actuated, we remove, inspect, and repair the actuator—whether electric or pneumatic—and reassemble it for seamless integration and reliable performance.
Leak & Pressure Testing (Hydrostatic & Pneumatic)
All repaired butterfly valves are rigorously tested to confirm leak-tight performance under pressure. We conduct hydrostatic or pneumatic testing, with full certification provided.
FAQs
How do I know if my butterfly valve needs repair?
Signs include reduced flow control, leaking around the stem or seat, or trouble operating the valve handle or actuator.
What’s your typical repair turnaround?
Most butterfly valve repairs are completed within 3–5 working days. Faster service is available for urgent cases.
Can you service both manual and actuated butterfly valves?
Yes, we repair manual, electric, and pneumatic butterfly valves, including actuator disassembly and reassembly.
Do you replace seals and discs during the repair?
Absolutely. We inspect and replace worn seats, seals, and discs to ensure optimal sealing and performance.
Do you handle lined butterfly valve repairs?
Yes, we service PTFE and rubber-lined butterfly valves and maintain the integrity of the lining during the repair process.
Can you upgrade the valve while it’s being repaired?
Yes. We can upgrade components such as seats, driveshafts, or actuators depending on the application and requirements.
