Dwyer Instruments WE04 | 2-Piece flanged stainless steel ball valve
A full port 2-piece flanged SS ball valve is incorporated into the Series WE04 to provide excellent flow rates with little pressure loss. The valve has a 316 SS (ASTM CF8M) ball for improved performance, strengthened PTFE seats and seals for extended life, and a blowout proof stem for increased safety. Direct mounting of the actuators results in a small assembly suitable for confined places. It is possible to put limit switches directly on valves, providing for distant position indication.
