TLV Y8F is a Y-shaped flanged strainer with a drain plug designed for use with steam, water, air, and other fluids. It is engineered to remove solid particles from the medium, protecting the most sensitive plant components such as pumps, control valves, flow and heat meters from debris. The strainer efficiently removes solid particles which are larger than the size of the holes in the screen mesh.

WARNING

Do not use for toxic, flammable or otherwise hazardous fluids.

Features

1. Simple yet rugged construction ensures long service life.
2. Screen made of durable stainless steel.
3. Designed for easy inline cleaning and maintenance.
4. DN 150 and larger screens have a perforated stainless steel supporting basket.
5. Precise screen guidance in cover and body.

Installation

During the installation of the strainer, ensure the following steps are observed:

• Visually inspect the strainer initially to ensure it is undamaged.
• Remove dust caps if supplied and check that the strainer body is free of solid particles.
• The pipeline where the strainer is fitted should be arranged in such a way that the strainer body is not subjected to any bending or stretching forces.
• Install the strainer in such a way that flow direction matches that of the arrow placed on the body.

TIP

The strainer body throat with screen should be positioned downwards in order to allow any sludge to collect there.

If there is a risk of water hammer caused by condensate formation, the strainer body throat should be installed in the horizontal position.

Maintenance

Wire mesh filters do not contain moving parts and do not require any maintenance, with the exception of screen cleaning. Screen cleaning intervals should be established by the user depending on how dirty the medium is.

DANGER

Before taking up any service jobs make sure that the medium supply to the pipeline has been cut off, the pressure has been decreased to ambient pressure, the medium has been removed from the pipeline, and the plant has cooled down.

Precautions should be taken when touching the gasket between the body and the strainer cover. The gasket contains a metal core which may cause injury. Tighten the hexagon nuts of the cover bolts evenly and crosswise using a torque wrench.

Troubleshooting

Fault	Possible Reason	Remedy
No flow	Flange dust caps were not removed	Remove dust caps from flanges
Poor flow	Dirty screen	Clean or replace the screen
Poor flow	Clogged pipeline	Check the pipeline
Broken connecting flange	Bolts tightened unevenly	Replace the strainer with a new one
