Description
A check valve designed for high-temperature and high-pressure service, featuring a straight-through internal medium passage that minimises fluid resistance without altering flow direction. Utilises pressure self-tightening sealing with butt-welded end connections as standard. The valve disc closes rapidly, resulting in low water hammer pressure, and the sealing surface experiences minimal erosion when fully open.
