Frequently Asked Questions
Wafer type valves are more compact and generally more cost-effective, as they are sandwiched between flanges, reducing the overall weight and installation space compared to lug types.
For high-temperature or chemically aggressive environments, PTFE or Viton seats are recommended due to their superior thermal stability and chemical resistance.
Yes, by selecting the Stainless Steel (CF8/CF8M) disc and stem options, the valve can effectively handle various corrosive media.
The Model 15 is available in a wide range of sizes from 2 inches (50mm) up to 12 inches (300mm) to suit different piping requirements.
Absolutely. We utilize materials adhering to ASTM standards, such as ASTM A536 for ductile iron and ASTM A276 for stainless steel stems.
Regular inspection of the seat and lubrication of the stem are recommended. Thanks to our high-grade bushings, maintenance frequency is significantly reduced.
