INTRODUCTION

When ordering wire cloth, mesh size and wire diameter are critical

dimensions.

MESH SIZE

Mesh size can be indicated by three different terms: Distance Between

Wires, Mesh per Inch, and Space Size.

THE DISTANCE BETWEEN WIRES

The Distance Between Wires dimension is the distance between adja-

cent wires, measuring from the center of both wires. The Mesh per

Inch dimension is the number of openings within an inch of the wire

cloth. This dimension is expressed as two numbers, such as 3 x 3,

which means there are three openings horizontally and three openings

vertically in one inch.

THE SPACE SIZE DIMENSION

The Space Size dimension, also known as clear opening, is the actu-

al open space between adjacent wires. This term is unique to space

cloth.

WIRE DIAMETER

Wire diameter indicates the thickness of the wire. As the wire gets thin-

ner, the opening width and open area dimensions get larger within wire

cloth of the same mesh size. For example, 2 x 2 mesh size with 0.120"

wire diameter has 57.8% open area, compared to 2 x 2 mesh with thin-

ner 0.047" wire diameter, which has 82.1% open area. Also, as the

wire diameter decreases, wire flexibility increases.

MESH

Mesh designates the number of openings and fractional parts of an

opening, per lineal inch. Mesh is determined by counting the number

of openings from the center of any wire to the center of a parallel wire,

one inch in distance. When the point one inch distant from the center

of a wire falls between wires within an opening, the mesh count is

expressed as a fraction.

Wire cloth is offered in six different styles to meet the demands of

your particular requirements. For more information about each style,

please contact a Cla-Val Regional Sales Office.

H Style Strainer

The Cla-Val Model X43H H-Style Strainer offers an effective means of

removing unwanted solid particles in pipeline flow. These strainers are

ideal for preventing fouling, and debris and particle buildup in Cla-Val

Automatic Control Valves. The large flow area design, with a flat stain-

less steel strainer mesh perpendicular to flow, is ideal for low pressure

drop applications.

Maintenance

The Cla-Val Model X43H is fast and easy to maintain with the compact

H-pattern, requiring service without removal from line. Routine mainte-

nance requires only removal of the top cover and removing unwanted

solid particles and debris from valve and wire cloth mesh strainer. The

strainer may be installed in any position, however, installation with cover

up is recommended.
