Maxitrol® 325 Series L-models are A.G.A./CGA certified
(Z21.80/CAN 6.22) for 2-psi or 5-psi inlet, commonly used with CSST or
semi-rigid copper tubing. The new Z21.80 standard requires the use of an
over-pressure protection device (OPD) for supply pressures above 2-psi, tested
and approved with the regulator. Maxitrol-built OPDs provide the required
downstream over-pressure protection.
Optional automatic vent limiting
devices eliminate the need to run vent piping from the regulator to a safe area.
In the event of a diaphragm rupture, gas escapement is limited to within ANSI
standards. Our manual ball valves are certified as well. All 325 regulators are
proudly made in the USA.
