Fisher™ Type HSR Pressure Regulators
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.
