Description

Asahi/America, Inc., the leading thermoplastics manufacturer providing customized solutions in fluid handling systems for a variety of industries, introduces the Type E Pressure Relief Valve.  These relief valves have been designed with a PTFE bellows stem seal and are available in body materials of PVC, PP, PVDF and PTFE, O-Ring seals of EPDM, FKM or PTFE encapsulated FKM, and in sizes from ½" - 4". The Type E Pressure Relief Valves feature light-weight construction, high flow coefficients, and no metal to media contact.
 
Drilled to an ANSI B16.5 bolt pattern, the Type E Pressure Relief Valves are versatile and can easily be installed in both thermoplastic piping as well as metal pipelines.  Being of Thermoplastic construction, these valves are highly corrosion resistant and are ideally suited for aggressive chemical applications in such industries as Chemical Processing and Waste Water Treatment.
