Pilot operation results in pressure control more precise than comparable direct operated valves. They feature external handwheel adjustment of reduced pressure and an external sensing port for installation of a gauge or optional connection to downstream piping. 11 Series reducing valves provide close control of steam pressure for the operation of many types of power plant equipment. In industrial plants they are used on such apparatus as ovens, stills, cookers, dryers, presses, pasteurizers, purifiers, sterilizers, mangles, washers, rendering machines, bleachers and vulcanizers. No valves are also widely used in office buildings, hospital and hotel heating systems. An internal pilot coupled with a large main valve plug assures precise, stable control with very high capacity for each valve size. Construction is of super-finished bronze and stainless steel for long term, maintenance-free service. On the valve, alloy stainless steel pilot and main valve plugs are carefully lapped to ensure tight shutoff. The No has a soft-seated main valve and pilot valve to ensure tight shutoff on air or gas service. Service Application Model Service Steam Air or Gas Note: Model may be used on air or gas applications, however the model will provide tighter shut-off characteristics Dresser Industries, Inc.

NOTE: No Valve is provided with a tapped connection which may be used for a gauge when external control pipe is not required. This connection should be utilized as an external connection when expanded outlet piping is used (or when valve is installed in a line larger than nominal valve size), to insure maximum efficiency and accuracy of control at above capacities. 1 Valve capacity tables are included to provide convenience on common applications they are not intended to establish application limitations. If your particular service conditions are not listed in the valve capacity table, calculate the required C V for selecting the optimum regulator size. 11 Series Reducing Pilot Operated Pressure Regulators 4
