Marine Y Type Strainer
Typical Applications
Marine Y‑type strainers are usually installed on the inlet side of hydraulic control valves, pressure‑reducing valves, steam traps, and similar equipment.
They are widely used in:
Seawater cooling systems
Fuel oil and lubricating oil pipelines
Compressed air systems
Steam systems
Overview
Main Features：
• Compact Y‑shaped design – shaped like the letter “Y”, it takes up little space, making it ideal for installation in the confined engine rooms of ships.
• High‑efficiency debris filtration – the built‑in stainless steel filter mesh effectively traps impurities like shells, seaweed, sand, and silt from seawater, with a filtration efficiency of over 99%.
• Easy maintenance – the filter element is typically removable, allowing for convenient cleaning or replacement at regular intervals.
• High flow capacity – some marine models are designed for large flow rates, offering a larger filtration area to minimise pressure drop and reduce clogging‑related flow reduction.

Key to dimensions:
DN – Nominal diameter
d – Pipe bore (connection size)
L – Face‑to‑face length (distance between inlet and outlet faces)
D – Flange outside diameter
C – Bolt circle diameter
H – Overall height
t – Flange thickness
n‑d – Number of bolt holes × hole diameter
