The"Arrestor" Fugitive Emission Valve
Environmental pollution is a global issue. Environmental regulations impacting plant operations include valves. The "ARRESTOR" OS&Y
valve is utilized with gage glass, mag gage or other apparatus when process fluid vapors or gases are considered to be environmentally
harmful.
Penberthy's "ARRESTOR" valves are individually serialized and tested to meet EPA emission test requirements. Each valve (550R/750R
valve) is shipped with its individual test report that certifies less than 5 ppm methane equivalent leak rates using Kalrez® packing.
Kalrez®/ Zymaxx™, API 607 III Edition Fire Test qualified, is a packing material option.
Models 551R/751R are available with type-accepted packing, rated to leak rates of 500 ppm methane equivalent.
Optional materials of construction can be specified for the valve body and trim. (Trim consists of the stem, stem packing retainer,
ball and seat.) Reference Penberthy Material Specification sheets for optional materials.
Model 530R and 730R center-to-center dimensional information corresponds to the fugitive emission 550R/551R and 750R/751R valves,
respectively.
