DESCRIPTION Model series WTA inert isolation valves offer great performance and a choice of wetted materials for compatibility with aggressive media. The valves utilize unique soft elastomeric seals that are forgiving of particulate matter that would typically destroy an inert valve.
The WTA series are a two way, normally closed configuration. Model WTA-2R have molded PPS bodies and Model WTA-2K have molded PEEK bodies. The valves have PTFE isolation diaphragms and a Perfluor or Viton soft valve seat seal.
