Strict safety protocols must be followed before cleaning Y-strainers to prevent leakage and personal injury caused by operation under pressure.
System Isolation & Pressure Relief: Shut off the upstream and downstream valves of the strainer to cut off the fluid flow. Slowly open the drain valve or vent port to fully release internal pressure, which can be confirmed when the pressure gauge reads zero or no medium flows out.
Tools & Personal Protective Equipment: Prepare adjustable wrenches, soft bristle brushes, high-pressure water guns, neutral detergent, clean rags and spare gaskets. Wear protective gloves and goggles to avoid splashing medium and chemical corrosion.
Operating Condition Recording: Record the differential pressure across the strainer, medium type and operating duration, to support the optimization of future maintenance schedules.
Flanged Type: Loosen bolts evenly in a diagonal sequence to prevent cover deformation and gasket damage due to uneven stress. Take off the cover and gasket, and store them properly to avoid loss and contamination.
Threaded / Quick-Disconnect Type: Slowly unscrew the cover with a wrench and watch out for residual medium spray.
Take out the internal filter screen assembly, and inspect it for damage, deformation or severe corrosion.
Initial Rinsing: Rinse the screen from the inside out with clean water or a high-pressure water gun to remove particulate impurities and sediments on the surface.
Remove Stubborn Dirt: Soak the screen in neutral detergent for 30 to 60 minutes, then gently scrub the mesh with a soft brush. Do not use hard tools such as wire brushes, which may damage the mesh structure.
Post-Cleaning Inspection: Rinse the screen thoroughly with clean water until the outflow runs clear. Make sure all meshes are unclogged and intact.
Wipe the interior of the strainer body to clear residual dirt and impurities and avoid secondary contamination.
Inspect the cover gaskets and sealing rings. Replace them with new ones of the same specification once aging, hardening or damage is found, so as to prevent leakage after reassembly.
Install the cleaned filter screen back into the body in the correct direction (the screen opening shall face the fluid inlet; positioning grooves are equipped on some models for easy installation).
Tighten the cover bolts evenly in a diagonal order to ensure a tight seal.
Slowly open the downstream valve to fill the pipeline with medium and vent all air. Then gradually open the upstream valve to restore system pressure. Finally, check all connections for leakage.
Targeting the maintenance pain points of industrial users, J-VALVES A105 Y-strainers adopt multiple optimized designs to greatly simplify cleaning work and cut downtime:
Quick-Disconnect Cover Structure: Standard flange bolt layout combined with anti-slip nuts enables fast disassembly without special tools. A single cleaning session can be finished within 15 minutes, improving efficiency by over 50% compared with conventional models.
Modular Filter Screen Assembly: The screen is connected to the body via positioning clips, requiring no complicated alignment during removal and installation. Reinforced screen edges effectively reduce the risk of deformation during cleaning.
Durable Sealing System: FKM gaskets or spiral wound gaskets feature excellent medium corrosion resistance and anti-aging performance. They do not need frequent replacement during maintenance, lowering spare parts costs.
Anti-Clog Flow Channel Design: The angled Y-type flow channel minimizes dead zones for sediment accumulation. Combined with the 45° drain port, online draining is available under certain working conditions to reduce disassembly and cleaning frequency.
