When you size a sanitary strainer, the headline number is rarely the mesh—it is the pressure drop. An angle type strainer and a Y type strainer both protect pumps and valves from solids, but their internal geometry makes them resist flow very differently. Here is how to compare them in real process terms.
Flow resistance comes from how sharply the fluid turns inside the strainer. An angle strainer turns the flow 90° through an elbow body; a Y strainer turns it through a shallower “Y” branch. The sharper the turn and the longer the screen, the higher the loss for a given flow rate.
The sanitary angle type strainer fits where a straight inline strainer will not—typically at a pipeline corner. Its 90° turn concentrates the loss at the bend, so for a given mesh it usually shows a slightly higher local pressure drop than a comparably sized Y strainer, but it saves space and removes the need for a separate elbow fitting.
The sanitary Y type strainer keeps the flow closer to straight, which generally yields a lower pressure drop at the same mesh and flow rate. Its screen pulls out along the branch, simplifying basket cleaning without full line disassembly.
| Factor | Angle Strainer | Y Type Strainer |
|---|---|---|
| Flow path | 90° turn through elbow body | Shallow “Y” branch, near-straight |
| ΔP at equal mesh | Marginally higher local loss | Generally lower pressure drop |
| Space needed | Compact; replaces an elbow | Needs straight run clearance |
| Screen access | Basket from the side | Pulls out along the branch |
| Best fit | Corner installs, tight layouts | Long lines, low-head pumps |
If your line is space-constrained at a corner and the ΔP budget allows, the angle strainer is efficient. If minimizing pressure loss matters most—long lines, low-head pumps—the Y strainer is the safer default. Browse the full sanitary filter range or the tank accessories catalog to match size, mesh, and connection type.
Size the right strainer for your line
Share your flow rate and pipe size—EFUN will size an angle or Y strainer with the lowest practical pressure drop for your duty.
At the same mesh and flow, the angle strainer’s 90° turn usually gives a marginally higher local loss, but the difference shrinks with larger bodies and coarser mesh. Always compare at your actual operating flow rate.
High viscosity raises ΔP in both. The Y strainer’s straighter path and easier basket access typically make it the friendlier choice for viscous or frequent-cleaning service.
Yes—use a coarser mesh where the process allows, a larger body, or a lower-velocity line size. EFUN can model these trade-offs for your specific duty.
