Process scope
Yoshitake strainers protect valves, traps, meters, and process equipment from debris. The local range includes Y-type, quick-opening, duplex, and high-pressure flanged designs. Selection must reconcile medium, screen mesh/perforation, pressure-temperature rating, pressure loss, cleaning frequency, and the required connection.
Project-specific checks
- Provide fluid, solids type/size/load, target screen opening, acceptable pressure loss, and cleaning interval.
- Confirm operating and design pressure-temperature values, corrosion conditions, and screen/body material compatibility.
- Match connection, installation direction, blowdown arrangement, cover-removal clearance, and support.
- For duplex service, define uninterrupted-operation expectations and lockout/isolation procedure.
Final verification
This guide groups local Yoshitake catalogue pages for preliminary engineering review. The model-specific Yoshitake documentation, sizing calculation, materials confirmation, and applicable site requirements control the final order and installation decision.
