Series 550/750

The"Arrester" Fugitive Emission Valve
Environmental pollution is a global issue. Environmental regulations impacting plant operations include Gagecocks. The "ARRESTER" OS&Y Gagecocks are utilized with gage glass, mag gage or other apparatus when process fluid vapors or gases are considered to be environmentally harmful.

Penberthy's "ARRESTER" Gagecocks are individually serialized and tested to meet EPA emission test requirements. Each set of Gagecocks (550R/750R Gagecock) 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 Gagecock 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 Gagecocks, respectively.
