The ULTRA-TROL® is designed for lined pipe applications requiring flanged end connections. The internal design features are similar to the HI-100®. They include the in-line through ported venturi flow shape and the contained spherical ball. These basic features enable the valve to operate smoothly and efficiently at high or low temperatures and in slurries. The ball, cage and stem can be easily replaced in-line without removing the valve from the line. The downstream seat is end loaded for quick replacement.
