In these applications, this DST11 Basket Type Strainer ensures precise fluid control, maintains excellent sealing integrity, and supports efficient, safe operation even under demanding conditions.
The DST11 Basket Type Strainer is an essential pipeline component specifically engineered to mechanically remove substantial amounts of solids, scale, and particulates from liquid pipelines, providing superior protection to sensitive downstream equipment. Designed to meet the stringent demands of modern infrastructure, this specialized strainer ensures continuous operational reliability and long-term durability by handling high debris loads effectively and simplifying cleaning.
At the core of the DST11 Basket Type Strainer is its vertically oriented chamber housing a deep, removable filter basket. This configuration provides a significantly larger surface area for filtration compared to Y-type strainers, enabling the system to run longer between cleaning cycles. The vertical housing ensures that captured solids settle into the basket base, safely away from the main flow path, thus minimizing flow disruption and maintaining a low overall pressure drop.
Manufactured from high-strength, corrosion-resistant materials and built with a robust flanged body, the DST11 Basket Type Strainer is designed to withstand continuous system pressure and challenging operating environments. Its most notable feature is the quick-opening hinged cover, which allows technicians rapid, tool-free access to the basket. This feature minimizes the downtime required for cleaning and inspection, which is critical for high-volume process applications.
The DST11 Basket Type Strainer is ideally suited for applications in petrochemical processing, power generation water treatment, fuel handling systems, and any high-flow, large-volume system where the capture of heavy solid loads is required. Its high capacity and rapid access maintenance feature make it a preferred choice for engineers seeking a high-integrity, standards-compliant solution for long-term system protection and continuous operation.
In summary, the DST11 Basket Type Strainer offers an optimal combination of high debris capacity, superior filtration efficiency, and unparalleled ease of maintenance. With its deep basket design, durable construction, and quick-access cover, this unit stands as a trusted solution for modern fluid control and equipment protection requirements worldwide.
1. General Information
The DST11 Basket Type Strainer is designed for the mechanical removal of heavy foreign matter from pressurized fluid systems. Proper installation is essential to guarantee safe operation, long service life, and sustained protection of downstream components.
2. Safety Precautions
Installation must be performed by qualified personnel only.
Ensure strict compliance with all local safety regulations and standards concerning working with pressurized pipelines.
Wear appropriate personal protective equipment (PPE).
Confirm that the pipeline section is fully depressurized and isolated before attempting to install the DST11 Basket Type Strainer.
3. Pre-Installation Checklist
Inspect the DST11 Basket Type Strainer for any visible damage during transport or storage, paying attention to the cover hinge mechanism and basket screen integrity.
Check that the strainer type, size, and pressure rating match the system requirements.
Verify that the strainer basket and housing interior are clean and free from debris.
Confirm that the mating pipeline flanges are properly aligned (parallel and concentric) and free from burrs or sharp edges. Ensure sufficient overhead clearance is available to fully open the hinged cover and vertically lift the basket during maintenance.
4. Installation Procedure
Positioning: Install the DST11 Basket Type Strainer ensuring the flow direction matches the arrow cast on the body. The strainer body must be installed in a horizontal pipe run with the basket chamber oriented vertically downwards for effective debris collection.
Use the appropriate gaskets suitable for the medium and operating conditions.
Align the strainer precisely between the pipeline flanges and insert bolts, tightening them gradually and crosswise in incremental steps. This ensures even compression of the gasket and prevents stress on the strainer body.
5. Post-Installation
Slowly reintroduce fluid and pressurize the system, checking for leaks around the flange connections and the hinged cover seal. If leakage is detected, depressurize the system immediately and re-tighten the bolts or secure the cover latch. Record the installation details, date, and initial pressure drop readings for documentation purposes.
Proper maintenance extends the service life of the DST11 Basket Type Strainer and ensures continuous debris removal and minimum pressure loss. Follow the guidelines below to maximize the longevity of this essential unit.
1. Routine Operation
Visually inspect the DST11 Basket Type Strainer exterior regularly for signs of external leakage, especially around the quick-opening cover and drain plug. Monitor the pressure differential across the strainer; a significant pressure drop indicates the screen requires cleaning.
2. Inspection Schedule
Monthly, check the area surrounding the strainer for any signs of external leakage.
Quarterly, check the internal basket condition by fully opening the hinged cover (only after depressurizing and draining the housing).
Annually, perform a detailed inspection of the strainer body’s coating integrity and verify the quick-opening mechanism latches securely.
3. Lubrication
The DST11 Basket Type Strainer does not contain internal moving parts that require lubrication; however, the threads on the quick-opening cover bolts or hinge should be kept clean. Apply a light anti-seize compound to the quick-opening mechanism threads to ensure easy access for cleaning.
4. Seal and Gasket Replacement
Replace the hinged cover gasket immediately if persistent external leakage is observed. The strainer basket should be inspected for tears or deformation; replace the basket if any damage is found to prevent debris ingress into the downstream system. Always isolate the strainer and fully depressurize and drain the housing before attempting to open the quick-opening cover.
5. Cleaning
Clean the strainer basket by removing the quick-opening cover and lifting the basket vertically for physical cleaning (rinsing, brushing) outside of the process line. Keep the exterior of the DST11 Basket Type Strainer clean to prevent surface corrosion.
6. Storage and Spare Parts
Store spare parts (gaskets, replacement baskets) in a dry, clean, and cool environment, away from direct sunlight and temperature extremes. Maintain a detailed record of all inspections, screen cleaning cycles, and repairs performed on the DST11 Basket Type Strainer unit.

Frequently Asked Questions about the DST11?
What are the main advantages of this valve?
The DST11 Basket Type Strainer offers superior debris retention capacity and quick access for cleaning via its hinged cover, minimizing process interruptions and providing robust protection to downstream pumps and valves.
Why should I choose this product?
This valve delivers outstanding performance in both sealing and durability, making it a dependable choice for demanding applications. Its straightforward design facilitates easy installation, offering flexibility during system design. With a wide range of material options, it meets the needs of various infrastructure projects, from municipal water networks to industrial facilities.
What is the key advantage of the Basket Strainer design over the Y Type Strainer?
The main advantage is the significantly increased dirt holding capacity offered by the deep basket, which allows the DST11 Basket Type Strainer to operate much longer between cleaning cycles than a compact Y-Type strainer.
How is the process line protected when accessing the basket?
When the basket is accessed, the line must first be depressurized and the strainer housing drained, as the DST11 Basket Type Strainer uses a hinged cover which requires the line to be completely isolated and emptied for safe cleaning.
Is the DST11 Basket Type Strainer suitable for high-viscosity fluids?
Yes, the large filtration area and minimized resistance of the DST11 Basket Type Strainer make it particularly well-suited for high-viscosity fluids where maintaining a low pressure drop and high flow rate is essential.
