GRACO 234257 - Low Back Pressure Fluid Regulator, 145 Max psi, 15-145 PSI Range, 4.6 GPM, SS, Air Type, 3/8"(F) x 3/8"(F), 1/8" BSPP Port
Air controlled, low pressure back pressure fluid regulator designed for precise pressure control in low-pressure fluid systems. Features stainless steel construction for durability and corrosion resistance, making it ideal for demanding industrial applications requiring consistent pressure regulation.
Features:
This back pressure regulator limits the supply pressure to a set value by opening an outlet and guiding back excess material when the predetermined pressure has been achieved. These valves are used in circulating systems.
