FAQ

Q: When should I use a butterfly valve?

A: Butterfly valves are ideal for large diameter systems where cost, weight, and space efficiency are important.

Q: What is the difference between wafer and lug butterfly valves?

A: Wafer valves are more compact and cost-effective, while lug valves allow easier maintenance and isolation.

Q: Are butterfly valves suitable for high pressure?

A: Standard butterfly valves are used for low to medium pressure. For high pressure, triple offset designs are recommended.

Q: Can butterfly valves be used for throttling?

A: Yes, butterfly valves can be used for flow regulation in many applications.

Q: What is your delivery time?

A: Standard products are typically delivered within 7–20 days depending on specifications.
