ANSI 2-Way/3-Way Plug Valves

ANSI 2-Way/3-Way Plug Valves
Product Types and Functions:

1.Two-Way Plug Valve (2-Way)**: Used for connecting or shutting off media, similar in function to globe valves or gate valves, but with faster opening and closing.

2.Three-Way Plug Valve (3-Way)**: Features one inlet and two outlets (or vice versa). By rotating the plug.

the following flow paths can be achieved:1. L-Type Flow Path: Switches the flow direction between two outlets (one inlet to one outlet, with the other outlet closed). 2. T-Type Flow Path: Enables flow merging (two inlets to one outlet) or flow splitting (one inlet to two outlets).

Core Features:

1.High Pressure Adaptability: Designed and manufactured in strict compliance with pound-class standards, offering high pressure-bearing capacity suitable for pressure systems such as Class150, 300, 600, and 900.

2.Flexible Flow Path Design: The three-way type enables flow direction switching, merging, and splitting without the need for multiple valves and pipe connections, simplifying system design.

3.Quick Opening/Closing and Easy Operation: Only a 90° rotation is required to complete flow path switching or opening/closing, supporting operation via handwheel, gearbox, or actuator.

4.Reliable Sealing and Long Service Life: The plug and valve body are precision-ground for optimal fit, with options for lubricated or soft sealing structures. Some models support the injection of sealing grease to enhance sealing and extend service life.

5.Compact Structure and Easy Installation: Compared to flow path systems composed of multiple valves, the three-way plug valve offers a higher level of integration, saving space and installation costs.

Main Technical Parameters:

1.Specifications & Connections: Pressure ratings Class150–Class900; Nominal diameters ½"–8" (DN15–DN200); Connection methods include threaded, flanged, and butt-weld.

2.Materials & Sealing: Valve body and plug materials include carbon steel, stainless steel, alloy steel, etc.; Available with metal hard seals, lubricated seals, or PTFE/rubber soft seals.

3.Operating Conditions & Actuation: Applicable temperature range -29℃ to +425℃ (depending on material and sealing type); Optional manual, gear-operated, or pneumatic/electric actuator actuation.

4.Applicable Media: Suitable for oils, natural gas, steam, water, and various chemical media.

Typical Applications:

1.Oil & Gas: Pipeline switching, filling systems, compressor inlets/outlets, oil-gas separation equipment.

2.Chemical Processes: Reactor feed switching, catalyst injection, multi-stream media distribution.

3.Marine Systems: Fuel switching, ballast water control, seawater/freshwater conversion.

4.Energy & Power: Steam drainage systems, boiler feedwater switching, heat exchanger flow direction control.

5.General Industry: Hydraulic systems, lubrication systems, gas distribution units.

Selection Key Points:

1.Select the pressure class and material based on system pressure and temperature.

2.Choose between two-way (shutoff) or three-way (switching/distribution) configurations according to process requirements.

3.For three-way valves, specify L-type or T-type flow path functionality.

4.Select the operation method based on automation needs.

Installation Considerations:

1.Confirm that the valve’s flow path direction aligns with system requirements before installation.

2.Use appropriate sealant for threaded connections and avoid introducing it into the flow passage.

3.Ensure proper alignment and evenly tighten bolts for flanged connections.

4.Allow sufficient space for operation and maintenance.
