Danfoss utilizes laser welding, which produces the new slim ball valve body. Brass-to-brass laser welding has a number of advantages, including lighter valves because less brass is needed, and less likelihood of damage to sensitive valve internals because laser welding requires less heat input than plasma welding.
"Because it's a lot slimmer, this valve is very appealing as a replacement valve, where technicians are working in very tight spaces," said Jeffrey Douglas, vice president, aftermarket of Danfoss North America. "And, the ultra-low leak potential offers a secure feeling other valves just don't provide."
