Threaded Y Type Strainer
Technical Parameters (General Reference)
Nominal pressure – Common ratings include PN1.0, PN1.6, PN2.5, PN4.0 MPa, etc.; for American standards, 150Lb, 300Lb, etc.
Operating temperature – Depending on materials, the range can be very broad, from –30 °C up to 425 °C.
Connection standard – Threads are typically NPT (American) or BSPT (British) standards.
Overview
Main Features:
Compact structure: The Y‑shaped design makes it simple and small in size, easy to install in pipelines with limited space.
Low flow resistance: The straight‑through flow path ensures fast passage, low fluid resistance, and minimal pressure loss, maintaining system efficiency.
Convenient blowdown/cleaning: Cleaning is easy: simply open the bottom blowdown valve or remove the screen cover to take out the filter element for maintenance.
Wide application: Suitable for many media, including water, oil, gas, and steam.
Variety of materials: Common body materials include A3 steel, 304/316 stainless steel, cast iron, and brass. Sealing materials are often PTFE or NBR, chosen to suit different corrosion resistance and temperature requirements.
High filtration accuracy: Mesh screens of different mesh counts can be provided as needed. For water service, 18–30 mesh is typical; for oil service, up to 100–480 mesh is available.
