Relief valves for air and gas services with models to ASME section VIII, gas ‘UV’, National Board certified and PED certified for non-hazardous gas.
These valves are suitable for use on multi- stage high pressure compressors, intercoolers and aftercoolers; on high pressure receivers and storage bottles, for thermal expansion relief and on breathing air pac and sCUBa recharge compressors.
-
lightweight aluminum construction is resistant to environmental and internal corrosion.
-
repetitively consistent opening pressure.
-
smooth relief action.
-
Positive reseating with minimal pressure
drop.
-
soft seat option provides repeatable
leak-tight performance; allows reduced maintenance costs, multiple cycles with tight shut-off and high seating integrity (Models 330, 330s and 333s).
-
Model 230 (non-code) is direct spring-loaded design with synthetic disc insert.
-
Model 330 series’ differential mechanism maintains a predetermined seat contact load.
-
full spring load is never imparted to synthetic
disc insert (Models 330, 330s and 333s).
-
seat tightness increases as inlet pressure
approaches set (opening) pressure.
-
each valve tested and inspected for pressure
setting and leakage.
