Ball Valve FAQ
Q: What maintenance does a ball valve require?
A: Ball valves are relatively low maintenance but should be periodically inspected for leaks and proper operation. Lubrication of the stem may be needed for manual valves, while actuated valves require checking of pneumatic or electrical components. For critical applications, we recommend scheduled maintenance every 6-12 months depending on service conditions.
Q: How do I select the right ball valve for my application?
A: Consider these factors when selecting a ball valve: 1) Media type (liquid, gas, corrosive substances), 2) Pressure and temperature requirements, 3) Flow characteristics needed (full port vs standard), 4) Connection type matching your piping system, and 5) Operational requirements (manual or automated). Our technical team can assist with specific application recommendations.
Q: What's the difference between floating and trunnion mounted ball valves?
A: Floating ball valves have a ball that moves slightly downstream to create a seal under pressure, suitable for smaller sizes and lower pressures. Trunnion mounted ball valves have mechanical anchors at top and bottom, handling higher pressures (typically 4" and larger). Trunnion designs offer lower operating torque and better sealing in high-pressure applications but come at higher cost.
Installation Guidelines for Ball Valves
For optimal performance of your ball valve:
- Install with proper alignment to piping - avoid forcing misaligned connections
- Consider flow direction if specified (some designs are unidirectional)
- Allow adequate space for operation and future maintenance
- Protect threads from damage during installation
- For buried service, use proper protective coatings
- Follow torque specifications when tightening connections

More Ball Valve Questions Answered
Q: Can ball valves be used for throttling applications?
A: While possible, ball valves are not ideal for frequent throttling. Extended partial-open operation can cause seat erosion and premature failure. For flow control applications, we recommend using specially designed control valves or considering V-port ball valve designs that provide better flow modulation characteristics.
Q: What causes a ball valve to leak?
A: Common causes of ball valve leakage include: worn or damaged seats (especially from excessive throttling), stem packing wear, improper installation torque, foreign material in the sealing surfaces, and thermal expansion/contraction in extreme temperature applications. Most leaks can be addressed through proper maintenance or component replacement.
Specialty Ball Valve Options
We offer customized solutions for demanding applications:

- High-Pressure Ball Valves: 5000+ PSI ratings for hydraulic systems
- Multiport Ball Valves: 3-way and 4-way configurations for flow diversion
- Lockable Ball Valves: Tamper-resistant designs with padlock provisions
Ball Valve Service Life Considerations
Q: How long should a ball valve last in service?
A: Service life varies significantly based on application conditions. In typical water service with proper installation, quality ball valves can last 15-25 years. For more demanding services like chemical processing or high-cycle applications, expect 5-10 years. Factors affecting longevity include media corrosiveness, operating frequency, temperature extremes, and maintenance practices. Our premium valves often exceed these averages due to superior materials and construction.
