Regulatorsuitable for 300 bar intel pressure and imported safety pressure gaugesdesigned for 400 bar pressure, confirming to ISO 5171 standards. Much morerugged, Longer life.
Much biggerplenum chamber (two stage plenum chamber is 5 times the volume of Single stageplenum chamber) ensures: Outlet pressure stability, Steady flow of gases. Fire-retardantvalve material.
StainlessSteel Diaphragm in Single stage - can withstand stock of full cylinderpressure.
Neoprenevalve in two stage Gives flexibility and better pressure regulation. Look forSeal of Safety.
