Groth Corporation announces a line of relief valves designed for environments too corrosive for metallic or fiberglass valves. Constructed of non-metallic, corrosion resistant materials, these valves will operate in highly caustic environments not suitable for metal and fiberglass. The all-polymer internal construction enables these valves to operate in the harshest chemicals, making them ideal for use with Chlorine, Ethylene Dichloride, Hydrochloric Acid and other corrosive materials.
Polymer valves operate in a similar fashion to their metal and fiberglass counterparts. They protect low-pressure atmospheric storage tanks from excessive pressure and/or vacuum and limit fugitive emissions by preventing constant tank “breathing” to atmosphere. The Non-Metallic Pressure and/or Vacuum Relief Valve is available in vent to atmosphere or pipe-away configurations.
