Strainer

As a Strainer Supplier in Dubai, UAE Valves provides industrial strainers that protect pumps, meters, turbines, and control valves from damage caused by debris and suspended solids. By removing unwanted particles before they reach critical equipment, our pipeline strainers ensure reliable performance, reduce downtime, and lower maintenance costs across oil, gas, water, power, and process industries.

How Strainers Work

Strainers are mechanical filtration devices installed in pipelines. Flow enters the body and passes through a perforated or mesh screen, which traps debris and allows clean fluid to pass downstream. Collected solids remain inside the basket or screen chamber until removed. Differential pressure across the screen signals when cleaning is due. Depending on the design, operators can clean strainers by removing the cover and basket or by flushing debris through a blow-down port without interrupting service.

Benefits of Strainers

• Shields rotating and sealing equipment from damage and unplanned shutdowns
• Maintains a stable pressure drop with screen areas sized to duty conditions
• Quick access covers and drain ports enable fast, safe cleaning
• Screens available in perforated and fine mesh to match particle size and service requirements
• Designed for seamless integration with isolation valves, DP gauges, and plant monitoring systems

Types of Strainers

• Simplex Basket Strainer – single housing with removable basket for planned shutdown cleaning
• Duplex Basket Strainer – dual housings with changeover valve for continuous operation while one basket is cleaned
• Y Strainer – compact inline strainer for light-duty protection on steam, gas, and liquid lines
