AirTAC 2KL Series Fluid Solenoid Valves
The AirTAC 2KL series is a 2-port solenoid shut-off valve spanning eight sizes from 030 to 500 with ports up to 2 inch, stocked in standard and 2KLH fluid variants and all five coil voltages.
inventory_2101 models availableSeries Overview
The 2KL is a 2-port (2-way) solenoid valve: two ports, two states, so it opens or shuts a line. It is a shut-off valve, not a directional valve - it does not drive a cylinder. Eight sizes make up the ladder: 030, 050, 150, 200, 250, 320, 400 and 500, with the port size climbing alongside, from roughly 1/8 inch at the small end to 2 inch at the top. All five standard AirTAC coil voltages are stocked: A (AC220V), B (DC24V), C (AC110V), E (AC24V) and F (DC12V).
Two variants share the ladder. The plain 2KL is catalogued simply as a solenoid valve and accounts for 101 of our 141 live SKUs. The 2KLH is catalogued as a fluid solenoid valve and accounts for 40 SKUs, concentrated in the smaller 030 and 050 sizes. The model code reads 2KL[H]{size}{port}{voltage}[I], and 70 of the 141 SKUs carry the I suffix - include it exactly as your drawing shows, and we confirm its meaning for your part.
Next to the sibling 2L series, 2KL keeps the same size ladder, the same five voltages and the same variant structure, but sits higher in price: a median of about $146 against about $119, with an entry price roughly twice 2L's. The two are not documented as interchangeable, so quote the exact code your drawing specifies. Across all 141 SKUs, listed prices run from about $97 to about $945, and price climbs steeply with size. Pressure, flow and temperature limits for any individual part are confirmed from the datasheet - send the model code with your RFQ.

Typical Applications
Automated production line isolation
A mid-range 2KL between machine sections gives the panel a switched on/off point for line isolation. The ladder runs 030 to 500 with ports up to 2 inch, so one series covers both branch and header duties.
Compact dosing and transfer skids
The 2KLH, catalogued as a fluid solenoid valve, is stocked in the small 030 and 050 bodies that fit tight skid layouts. Confirm the medium, pressure and temperature for your exact part number by RFQ.
Control panel retrofits on legacy voltages
Five stocked coils - AC220V, DC24V, AC110V, AC24V and DC12V - let a 2KL drop into older panels or low-voltage DC systems without adding a power supply or transformer.
Larger-bore shut-off duty
Sizes 320 to 400 and 500 span the top of the port range up to 2 inch for larger-diameter lines. Price climbs steeply with size, so quote the exact model code for a firm figure.
How to Choose the Right Model
First confirm the function: if the job is to open and close a line, a 2-port valve like the 2KL is right; if it is to move a cylinder, you need a 5-port directional valve from the 4V, 5V or 6V series, or the 4M NAMUR valve that mounts directly on the actuator. Within the series, match size and port to the line - the small 030 and 050 bodies suit compact panels and tight mounting, the 320 to 500 bodies span the top of the port range up to 2 inch. Where the fluid label matters to your duty, the 2KLH is stocked in the 030 and 050 sizes. Expect price to rise sharply with size, so sizing honestly pays.
Before ordering, confirm five points: (1) function - 2-port shut-off, not directional control; (2) size and port against your line; (3) medium, pressure and temperature - confirmed from the datasheet for your exact model; (4) coil voltage - A AC220V, B DC24V, C AC110V, E AC24V or F DC12V; (5) the complete model code, including the H fluid variant letter and the I suffix where present. Because 2L and 2KL are not documented as substitutes for each other, name the series your drawing calls for rather than swapping between them. Upstream of an air line, a GFR filter regulator or GC F.R.L. unit conditions the supply.

Frequently Asked Questions
Eight sizes: 030, 050, 150, 200, 250, 320, 400 and 500, with port sizes climbing from roughly 1/8 inch at the small end to 2 inch at the top. All five standard AirTAC coil voltages are stocked: A (AC220V), B (DC24V), C (AC110V), E (AC24V) and F (DC12V). We list 141 live SKUs, priced from about $97 to about $945 with a median around $146. Pressure, flow and temperature figures for any single model are confirmed from the datasheet - send us the code with your RFQ.
The catalogue titles the plain 2KL simply a solenoid valve (101 SKUs) and the 2KLH a fluid solenoid valve (40 SKUs). The fluid variant is stocked mainly in the smaller 030 and 050 sizes, so it is the compact option where the fluid label applies. Which media, pressures and temperatures each individual part approves is confirmed from the datasheet for that part number - we confirm it when you quote the exact code.
The two share the same size ladder, the same five voltages and the same variant structure, but they are not documented as substitutes for each other. The visible difference is commercial: 2KL sits higher in the price range, with a median of about $146 against about $119 for 2L, and an entry price roughly twice as high. Quote the exact series and model code your drawing or datasheet specifies, and we supply that code.
Yes - AirtacDistr is an authorized export seller of genuine AirTAC parts, and all 141 2KL and 2KLH SKUs are listed and orderable on the store. We do not publish live stock quantities, so lead time is confirmed on request with your RFQ. Note the function limit: this is a 2-port shut-off valve and does not drive a cylinder - for that you need a 5-port directional valve from the 4V, 5V or 6V series.
