161 Series Pilots for Pilot-Operated Pressure Reducing Regulators
161 Series pilots are mainly used in natural gas, air, or other non-corrosive gas applications. Their installation with pressure regulators foresees a Type 112 restrictor and a 161 Series pilot. For applications that have high-pressure drops, using a Type 161AYM or 161EBM monitor pilot will increase the accuracy of the regulator.
Type 161AYW pilot is a direct-operated monitoring regulator pilot with quick dump bleed and diaphragm casing tapped 1/2 NPT for control line connection.

- Available in Several Monitoring and Non-Monitoring Configurations
- Wide Outlet Pressure Capability Ranging from 3-inches w.c. to 350 psig
- Increases Regulator Accuracy when used for High Pressure Drop Applications
- Applicable for Natural Gas and other Non-Corrosive Gas Applications
Type 161—Downstream pressure range from 5 to 300 psig / 0,34 to 20,7 bar. Pilot bleed exhausts downstream through the sense (control) line.
Type 161M—Downstream pressure range from 5 to 300 psig / 0,34 to 20,7 bar. A static sensing (control) line is isolated from pilot bleed (exhaust). The Type 161M is used in working monitor and other application that require a sensing line isolated from pilot bleed (exhaust).
Type 161AY—Low-pressure pilot with an outlet pressure range from 6-inches w.c. to
7 psig / 15 mbar to 0,48 bar. Pilot bleeds (exhausts) downstream through the sense (control) line.
Type 161AYM—The monitor version of the Type 161AY pilot. The pilot bleed (exhaust) is isolated from the sense (control) line. This pilot is used in monitoring systems requiring an isolated pilot bleed (exhaust).
Type 161EB—High accuracy pilot with an outlet pressure range from 5 to 350 psig / 0,34 to 24,1 bar. Pilot bleeds (exhausts) downstream through the sense (control) line.
Type 161EBM—The monitor version of the Type 161EB pilot. The pilot bleed (exhaust) is isolated from the sense (control) line. This pilot is used in monitoring systems requiring an isolated pilot bleed (exhaust).
