Specifications Ambient Temperature Range: 15?F to 140?F (32?F to 122?F for proportional)
Pilot Fluid Temperature Range: 15?F to 140?F Maximum Viscosity:
The 8290 Series is suitable for the following applications:
? General Service (air, inert gas, water, oil, light slurries)
? Steam and Hot Water
COMPACT SIGNALING UNIT This unit has an extension rod in place of the standard visual indicator,
which contains the permanent magnet and field adjustable mini-detectors.
Valve stem position is sensed by one or two mini-reed switch detectors
with either an integral M8 3-pin connector or a 2 meter cable with leads.
Order “Support & Rod” and “Reed Switches”. (e.g., 855 29 032 & 881 00 140)
STROKE LIMITER The stroke limiter allows Cv flow to be adjusted from 0% to 100%,
and mounts on top of the 8290 Series valve in place of the position indicator.
Assembly available onto50mm (normally closed) and 63mm through 125mm normally
open or normally closed valves with fluid entry under the disc. Add suffix M: (e.g., 8290B002M)
LINEAR POSITION INDICATOR (HS SERIES) Supplied with two mechanical
Alternate Valve Constructions ? Oxygen service, add suffix "N".
? Medium vacuum service up to 7 x 10-3 Torr, add suffix "VM".
? Visual Position Indicator for normally closed valve with 32mm or 50mm operator,
add suffix “VI” (note: position indicator standard on 63mm through 125mm operators).
? NET-INOX treatment (stainless steel valve body pickled in nitric/hydrofluoric acid bath),
add suffix “NI”. ? All 316L stainless steel versions (available on request).
See inside back cover for the following constructions:
or REED switches and mounts on top of the valve operator in place of the standard visual indicator.
Provides a wiring box with conduit connections.
HS1,2,3 indicators are suitable for hazardous locations while the HS4 indicator is suitable for non-hazardous locations.
Optional AS-interface® and DeviceNet® communications available. Consult ASCO for details and ordering.
8290SERIES ACCESSORIES
COMPACT POSITIONERS FOR PROPORTIONAL CONTROL Varies flow proportional to a 0-10 VDC,
0-20 mA or 4-20 mA control signal. Feedback of valve stem position via a linear potentiometer.
Uses a profiled disc for flow characterization.
Assembly available on 50mm through 125mm operators,
normally closed with fluid entry under disc.
Positioner not suitable for water piloting.
(e.g., 8290A384PDB04) Control Signal Add Suffix 0-10 VDC PDB04 0-20 mA PDB05 4-20 mA PDB06
Support & Rod Reed Switch (Each) 50mm
Compact Positioner for proportional control Compact Signaling Unit

2,700 SSU For higher viscosity applications, please consult ASCO.
The 8290 Series consists of 2-way direct acting valves available in normally
closed or normally open constructions. Built for demanding applications,
these valves come in a straightthrough body design made of bronze or stainless steel.
There are many optional features including visual/electrical position indicator or a stroke limiter.
