Supported Applications

The Series 185 is a Smart Linear Valve Positioner that accurately controls the valve stroke of linear motion valves using a 4-20 mA DC input signal from the controller. A built-in microprocessor performs auto calibration, PID control and alarm functions and communicates over the HART protocol, while an analog feedback signal is output to stabilize the valve system.

Linear motion control valve and actuator positioning
Process loops requiring 4-20 mA input with HART communication
Installations needing field-adjustable PID and valve characterization (linear, quick open, equal percentage)

The positioner is rated NEMA 4X (IP66) and can manually actuate the valve or damper. An air filter regulator can be mounted directly to the positioner, and tight shut-close and shut-open can be set in the programming menu. HART is a registered trademark of Fieldcomm Group, Inc.

Operating Conditions & Performance

The Series 185 takes a 4-20 mA DC input signal with an input impedance of 460 Ω max @ 20 mA DC, and runs on an air supply of 35 to 116 psi (2.4 to 8 bar). Ambient operating temperature is -30 to 85°C.

Linearity: ±0.5% FS
Hysteresis: ±0.5% FS
Sensitivity: ±0.2% FS
Repeatability: ±0.3% FS
Air consumption: .0004 scfm (.01 LPM) at 20 psig (1.4 bar) supply
Flow capacity: 2.1 scfm (60 LPM) at 20 psig (1.4 bar) supply

The Series 185 handles a linear valve stroke of 0.5 to 6" and weighs 3.3 lb (1.5 kg). Pneumatic and electrical terminations are an Air Connection of 1/4" NPT, a Gage Connection of 1/8" NPT and a Conduit Connection of 1/2" NPT. Split ranges such as 4 to 12 mA, with 12 to 20 mA, are available.

Configuration Options

Series 185 models share the same linear-motion control electronics and HART communication, and differ by enclosure material to suit the installation environment.

Aluminum enclosure models provide the standard lightweight housing.
316 SS enclosure models provide stainless steel construction for corrosive or washdown environments.

Mounting to a linear actuator uses a feedback lever and lever spring with a flange nut on the bottom of the main shaft, secured with four M8x1.25P hexagon head bolts and four M8 plate washers.
