API 602 is a standard developed by the American Petroleum Institute (API) that specifies the requirements for compact forged steel gate valves, globe valves, check valves, and filters. It covers small-bore sizes with a maximum nominal diameter of NPS 4 (DN 100) and pressure ratings up to 2500 or 4500, depending on the design scope.
Valve Types: Gate valves, globe valves, check valves, and filters;
Size Range: 1/4'' ~ 2'' (DN8 ~ DN50);
Pressure Ratings: ANSI Class 150, ANSI Class 300, ANSI Class 600, ANSI Class 800, ANSI Class 1500, and ANSI Class 2500;
Valve Body Construction: Forged steel valve body, such as A105, F304, etc., with high pressure and high temperature toughness;
End Connections: Threaded connection, socket weld connection, flange connection, or butt weld connection.
Face-to-Face: Shorter structural length and smaller overall size compared to heavy-duty cast valves such as API 600;
Bonnet Options: Bolted Bonnet, Welded Bonnet, Pressure Sealing Bonnet, designed to prevent leakage under stringent operating stresses;
Emissions Compliance: Typically designed to meet fugitive emission requirements such as API 624 or ISO 15848-1.
1. Main Features of 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.
