The strainer is designed for use in conjunction with a Cla-Val
Main Valve, but can be installed in any piping system where
there is a moving fluid stream to keep it clean. When it is used
with the Cla-Val Valve, it is threaded into the upstream body port
provided for it on the side of the valve. It projects through the
side of the Main Valve into the flow stream. All liquid shunted to
the pilot control system and to the cover chamber of the Main
Valve passes through the X46 Flow Clean Strainer.

The Cla-Val Model X46 Strainer is designed to prevent passage of

foreign particles larger than .015". It is especially effective against

such contaminant as algae, mud, scale, wood pulp, moss, and root

fibers. There is a model for every Cla-Val. valve.

The X46 Flow Clean strainer operates on a velocity principle utilizing

the circular "air foil" section to make it self cleaning. Impingement of

particles is on the "leading edge" only. The low pressure area on the

downstream side of the screen prevents foreign particles from clog-

ging the screen. There is also a scouring action, due to eddy cur-

rents, which keeps most of the screen area clean.

INSPECTION

Inspect internal and external threads for damage or evidence
of cross-threading. Check inner and outer screens for clogging,
embedded foreign particles, breaks, cracks, corrosion, fatigue,
and other signs of damage.

CLEANING

After inspection, cleaning of the X46 can begin. Water service usually will produce
mineral or lime deposits on metal parts in contact with water. These deposits can
be cleaned by dipping X46 in a 5-percent muriatic acid solution just long enough for
deposit to dissolve. This will remove most of the common types of deposits.

Caution: use extreme care when handling acid.

If the deposit is not removed by

acid, then a fine grit (400) wet or dry sandpaper can be used with water. Rinse parts
in water before handling. An appropriate solvent can clean parts used in fueling ser-
vice. Dry with compressed air or a clean, lint-free cloth. Protect from damage and
dust until reassembled.

REPLACEMENT

If there is any sign of damage, or if there is the slightest doubt that the Model X46
Flow Clean Strainer may not afford completely satisfactory operation, replace it. Use
Inspection steps as a guide. Neither inner screen, outer screen, nor housing is fur-
nished as a replacement part. Replace Model X46 Flow Clean Strainer as a com-
plete unit.

When ordering replacement Flow-Clean Strainers, it is important to determine pipe
size of the tapped hole into which the strainer will be inserted (refer to column A or
F), and the size of the external connection (refer to column B or G).

When Ordering,
Please Specify:

• Catalog Number X46
• Straight Type or Angle Type
• Size Inserted Into and Size Connection
• Materials

DISASSEMBLY

Do not attempt to remove the screens from the strainer housing.
