Frequently Asked Questions

Q: What are the primary benefits of a wafer type butterfly valve over a lug type?

Wafer valves are more compact, lighter, and generally more cost-effective. They are installed between flanges, which simplifies installation and reduces the overall weight of the piping system.

Q: Which seat material should I choose for high-temperature applications?

For high-temperature or chemically aggressive environments, PTFE is the recommended seat material due to its superior thermal stability and chemical resistance.

Q: Are these valves compatible with automatic actuators?

Yes, our valves feature ISO 5211 top flange dimensions, ensuring they are compatible with a wide range of pneumatic and electric actuators.

Q: What is the maximum size available for the Wafer Butterfly Valve?

We provide a comprehensive size range, with the largest standard wafer butterfly valve available up to 48 inches.

Q: Which standards are used for the pressure testing of these valves?

Our valves are rigorously tested and inspected in accordance with API 598 and EN12266 standards to guarantee leak-proof performance.

Q: Can these valves be used for potable water systems?

Yes, by selecting EPDM seats and Stainless Steel discs, our valves are highly suitable for water supply and potable water applications.
