Asco 8267 Series Installation & Maintenance Instructions

Installation & Maintenance Instructions
NORMALLY CLOSED OR NORMALLY OPEN OPERATION
NOTICE: See separate solenoid installation and
maintenance instructions for information on:
Solenoid Temperature, Causes of Improper Operation, Coil
or Solenoid Replacement.
DESCRIPTION
Series 8267 valves are 2-way normally closed or normally
open direct-acting solenoid valves.
designed for steam service.
provides straight through flow, minimizing pressure drop
and turbulence through the valve. Series 8267 valves may be
provided with a general purpose, raintight/explosionproof
or raintight/watertight/explosionproof solenoid enclosure.
OPERATION
Normally Closed: Valve is closed when solenoid is
De-energized; open when energized.
Normally Open: Valve is open when solenoid is
De-energized; closed when energized.
Note: No minimum operating pressure differential
required. See nameplate for maximum.
INSTALLATION
Check nameplate for
pressure, voltage, frequency, and service.
incompatible fluids or exceed pressure rating of the valve.
Installation and valve maintenance to be performed by
qualified personnel.
Future Service Considerations
Provision should be made for performing seat leakage,
external leakage, and operational tests on the valve with a
nonhazardous, noncombustible fluid after disassembly and
reassembly.
Temperature Limitations
For maximum valve ambient and fluid temperatures, refer
to chart above. Check catalog number on nameplate to
determine maximum temperatures.

Positioning
Valve must be mounted with solenoid vertical and
upright.
Piping
Connect piping to valve according to markings on valve
body. Apply pipe compound sparingly to male pipe threads
only. If applied to valve threads the compound may enter
the valve and cause operational difficulty. Avoid pipe strain
by properly supporting and aligning piping.
tightening the pipe, do not use valve or solenoid as a lever.
Locate wrenches applied to valve body or piping as close as
possible to connection point.
CAUTION: To protect the solenoid valve, install a
strainer or filter, suitable for the service involved, in the
inlet side as close to the valve as possible. Clean
periodically depending on service conditions. See
ASCO Series 8600, 8601, and 8602 for strainers.
