China make LHSR Model Pressure Reducing Regulator Use For Gas Fired
Burner
Type HSR direct-operated, spring-loaded pressure reducing
regulators provide control in residential, commercial,
and industrial applications for natural, manufactured, or liquefied
petroleum gases.Internal relief across the diaphragm
helps minimize overpressure. Any outlet pressure over the
start-to-discharge point of the nonadjustable relief valve
spring moves the diaphragm off the relief valve seat, allowing
excess pressure to vent.Regulators meet ANSI B109.4/CGA 6.18.
