Frequently Asked Questions

Q: What are the primary advantages of a threaded butterfly valve over flanged ones?

Threaded butterfly valves offer much faster installation and a more compact footprint, making them ideal for space-constrained environments where heavy flanging is impractical.

Q: Which materials are used for the valve body to ensure durability?

We use high-grade Cast Iron (ASTM A126CL.B) or Ductile Cast Iron (ASTM A536) depending on the pressure and durability requirements of the application.

Q: Can these valves handle corrosive media?

Yes, with a corrosion-resistant surface treatment and available AL-Bronze discs and Stainless Steel stems, these valves are designed for longevity in challenging environments.

Q: What types of seals (O-Rings) are available for different temperatures?

We provide a variety of seals including NBR, EPDM, Neoprene, and Viton to ensure compatibility with various fluids and temperature ranges.

Q: How does the "easy clean" design benefit industrial operations?

The streamlined internal geometry allows for faster cleaning and inspection, which reduces the time required for maintenance and lowers overall operational downtime.

Q: What size range is available for these threaded butterfly valves?

Our current product line supports NPT sizes ranging from 2 inches up to 6 inches to fit a wide array of plumbing needs.
