The AR Series includes 90 degree, ASME approved relief valves. These provide very close control to keep piping systems safe from over-pressurization.

The ninety degree setup gives direct relief to the gases, so there is no flow through the spring. Like in the A8560, A8570, & AA8570 Series, a “bubble-tight” seal ensures complete shut off.  Cleaned for Liquid Oxygen Service per CGA G-4.1 100% Factory Tested.
