Type 14 provides good body-to-bonnet sealing performance, visual position indication, Weir design for throttling capabilities, and built-in travel stop to prevent overtightening and compressive strain. Bubble-tight sealing can be achieved even in applications containing suspended particles or slurries. The flanged diaphragm valve has a three-layered EPDM/PTFE diaphragm that can accept a PVDF gas barrier for aggressive chemicals. The valve is constructed as a molded, one-piece body.
