Figure 1 Mounting Dimensions
Positioning
These valves are designed to perform properly when mounted in any
position. However, for optimum life and performance, the solenoid
should be mounted vertically and upright to reduce the possibility of
foreign matter accumulating in the solenoid base sub-assembly area.
Mounting
Two (2) M5 threaded holes are provided in the valve body for mounting.
(See Figure 1)
Optional mounting bracket can be obtained with valve as Suf
fi x MB or
separately as a kit.
Piping
Connect piping or tubing to valve according to markings on valve
body. Inlet port will either be marked “1” or “IN”. Outlet port will
be marked “2” or “OUT”. Wipe the pipe threads clean of cutting oils.
Apply pipe compound sparingly to male pipe threads only. If applied to
valve threads, the compound may enter the valve and cause operational
dif fi culty. Avoid pipe strain by properly supporting and aligning piping.
When 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.
IMPORTANT: To protect the solenoid valve, install a strainer
or fi lter 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 and 8601 for strainers.
MAINTENANCE
WARNING: To prevent the possibility of death,
serious injury or property damage, turn off
electrical power, depressurize valve, and vent
fl uid to a safe area before servicing the valve.
NOTE: It is not necessary to remove the valve from the pipeline for
repairs.
Cleaning
All solenoid valves should be cleaned periodically. The time between
cleanings will vary depending on the medium and service conditions.
In general, if the voltage to the coil is correct, sluggish valve operation,
excessive noise or leakage will indicate that cleaning is required. In the
extreme case, faulty valve operation will occur and the valve may fail to
open or close. Clean strainer or fi lter when cleaning the valve.
Preventive Maintenance
•
Keep the medium fl owing through the valve as free from dirt and
foreign material as possible.
•
Periodic exercise of the valve should be considered if ambient or
fl uid conditions are such that corrosion, elastomer degradation,
fl uid contamination build up, or other conditions that could
impede solenoid valve shifting are possible. The actual frequency
of exercise necessary will depend on speci fi c operating conditions.
A successful operating history is the best indication of a proper
interval between exercise cycles.
• Depending on the medium and service conditions, periodic
inspection of internal valve parts for damage or excessive wear
is recommended. Thoroughly clean all parts. Replace any worn or
damaged parts.
Causes of Improper Operation
• Incorrect Pressure: Check valve pressure. Pressure to valve
must be within range speci fi ed on nameplate.
• Excessive Leakage: Disassemble valve (see Maintenance) and
clean all parts. If parts are worn or damaged, install a complete
ASCO Rebuild Kit.
Valve Disassembly (see Figures 2, 3 & 4)
1.
Disassemble valve using exploded views for identi fi cation of parts.
2.
Remove solenoid, see separate instructions.
3.
Unscrew solenoid base sub-assembly with wrench. Remove core
assembly, core spring, and solenoid base gasket from valve body.
4. For normally open construction (Figure 4) remove spring,and disc
holder assembly.
5.
All parts are now accessible to clean or replace. If parts are worn
or damaged, install a complete ASCO Rebuild Kit.
Valve Reassembly
1.
Use exploded views for identi fi cation, orientation and placement
of parts.
2.
Lubricate all gaskets with DOW CORNING® 200 Compound
lubricant or an equivalent high-grade silicone oil.
3. For normally open construction (Figure 4), install disc holder
assembly and disc holder spring.
4.
Replace solenoid base gasket, core assembly with core spring
and solenoid base sub-assembly. Note: For core assemblies with
internal type core springs, install wide end of core spring in core
assembly fi rst, closed end of core spring protrudes from top of core
assembly. (see Figure 2)
5. Torque solenoid base sub-assembly to 175±25 in-lbs [19,8±2,8
Nm].
6.
Install solenoid. See separate solenoid instructions. Then make
electrical hookup to solenoid.
WARNING: To prevent the possibility of death,
serious injury or property damage, check valve
for proper operation before returning to service.
Also perform internal seat and external leakage
tests with a nonhazardous, noncombustible fl uid.
7. Restore line pressure and electrical power supply to valve.
8. After maintenance is completed, operate the valve a few times to
be sure of proper operation. A metallic click signi fi es the solenoid
is operating.
ORDERING INFORMATION
FOR ASCO REBUILD KITS
Parts marked with an asterisk (*) in the exploded views in Figure 2 &
3 are supplied in Rebuild Kits. When Ordering Rebuild Kits for ASCO
valves, order the Rebuild Kit number stamped on the valve nameplate.
If the number of the kit is not visible, order by indicating the quantity
of kits required, and the Catalog Number and Serial Number of the
valve(s) for which they are intended.
