1. Brief Description

1.1 Y-Type Strainer: Extremely low flow resistance, compact structure, and easy maintenance;


2.11 Advantages of Y-Type Strainers:

① Small size and flexible installation; can be installed horizontally or vertically, even in narrow pipe locations;

② Simple structure, low cost, easy disassembly and maintenance, and convenient drainage;

③ Moderate flow resistance, low pressure loss for conventional clean media;

④ Wide pressure rating coverage, with corresponding specifications for normal pressure, medium-pressure, and high-pressure operating conditions.

 

2.12 Disadvantages of Y-Type Strainers:

① Very small impurity capacity of the filter screen, easily clogged, unsuitable for media with high impurity content;

② Poor manufacturing economy for large-diameter specifications; rarely used for sizes above DN200;

③ Filter screen subjected to oblique force; prone to deformation and damage under high pressure and high flow conditions;

④ High maintenance workload under frequent drainage conditions.

 

2.13 Main Application Areas of Y-Type Strainers:

① Water supply and drainage, HVAC circulating water, gas pipelines, compressed air pipelines;

② Small protective filters before valves and pumps (stop valves, solenoid valves, pre-protection for small water pumps);

③ Clean oil products in petroleum refining, steam pipelines, heat transfer oil pipelines;

④ Clean process media in chemical industry, fire protection pipelines, central air conditioning systems;

⑤ Pipe diameter range: DN15~DN200.


3. Selection Recommendations

3.1 For small-diameter pipes, clean media, and protective valves/pumps, a Y-type Strainer is recommended.

3.2 For small-diameter instrument pressure lines, a Y-type Strainer is recommended.

3.3 For steam systems with small pipe diameters, a Y-type Strainer is recommended.
