Parker 4 way valves are used to control the bi-directional flow of air and water in pipelines of water treatment facilities. These manual air control valves feature a stainless steel spool and fluorocarbon seals that provide the capacity to withstand higher temperatures and greater chemical compatibility. Although these units come pre-lubricated, they still recommend the supply of lubricated, clean air for added service life, even under an aggressive temperature range of -40 to 175 degrees F. They further come equipped with parallel and perpendicular mount handles for easy configuration and are available in aluminium and bronze body materials on Raptor Supplies.
