Webtec Launches Divider-Combiner Valve for Heavy-Duty Applications

Webtec, a specialist manufacturer of hydraulic measurement and control products, recently unveiled the FDC140, a new high-accuracy hydraulic flow divider-combiner valve.

Ideal for driving two cylinders or motors in close unison regardless of individual loads or flow direction, this high-flow spool valve is the big brother of the FDC60. The 140 in the name indicates a larger flow capacity of 140 lpm (37 gpm) and higher, making it perfect for large heavy-duty applications such as container handling systems, large-capacity forklifts, skip handling, synchronised crawler drives, loading ramps, and mining machinery.

FDC140 valves divide a single flow into two separate flows that will always be in the same ratio to one another regardless of any pressure differential (unequal load). The FDC140 delivers divisional accuracy of ±1.5%. If required, a single flow can also be divided into two unequal flows, with split ratios extending from 10% to 90% (in 10% increments).

The three-port FDC140’s high-pressure capability with maximum working pressure is rated at 350 bar (5,000 psi).

The FDC140 offers pressure compensation in both forward and reverse flow so the valve is fully bidirectional. If the flow is reversed, such as on the return stroke of two cylinders, the return flows are maintained at the same ratio to each other and combined in a single flow, regardless of individual loads on the cylinders.

Featuring a robust SG iron body, hardened steel components, and NBR seals, the FDC140 can be used with HLP mineral and synthetic oils, as well as HFC fire-retardant fluids. Operating fluid temperatures extend from -30°C to 100°C (-22°F to 212°F).

Port options include BSPP (1” with ¾”; and ¾” with ½”), SAE (#16 with #12; and #12 with #8) and metric (M33 with M27; and M27 with M22).
