The 1164 is a relief regulator suitable as a back pressure or bypass regulator for controlling inlet pres sure between 5 and 150 psig (0.34–10.3 Barg).
Three body materials and six trim material combinations allow compatibility with many fluids. A large orifice and diaphragm provide sensitivity with high capacity.
Tight Shut Off: A TFE composition seat is available. Sensitivity: A large diaphragm area plus no guiding friction assures positive reaction to the slightest change in pressure.
Designed for controlling a wide range of fluids in cluding air, inert gases, chemicals, water, fuel oil and steam. See Table 1 for more in for ma tion
