Reaping the benefits of accumulators
Supplementing pump flow is one of an accumulator’s most important jobs. Here we look at why and finish with a spotlight on some of the industry’s latest components.
Expandable valve manifolds
VS manifolding valve product range improves design, maintenance and performance of pneumatic systems in industrial machines, by allowing expansion of the manifold in the field without tearing it apart or replacing it. Modular design allows expansion of single stations by up to 16 valves.
Fully-submersible labels
CILS-8200 fully-submersible, computer printable rating plate labels resist seawater, gasoline, diesel, oils, chemicals, solvents, etc., for long-term identification. Printable in minutes from a laser, inkjet or thermal transfer printer, variable data (serial numbers, barcodes etc) can be added in-house, saving time and costs.
Compact CAN controller
CAN-IO14 control unit has four proportional outputs and four pulse-width modulation (PWM) outputs, which can also be configured as inputs. Output ports combined with six analog inputs have ranges between 0 to 10 V and 4 to 20 mA, offering simplified wiring and decentralized control of components.
Low-temperature hose
New 472LT and 722LT hoses work in temperatures from –70°F to 212°F (–57°C to 100°C). They are designed for high-impulse, applications. The 472LT is available in 1⁄4- to 1-in. sizes. No-skive, two-wire braided hose is rated for pressures to 5800 psi (40 MPa).
Cartridge valves
Series 09 cartridge valves for proportional and on/off pilot control of clutches, brakes and directional control valves are a hybrid product that combines 10 size cavity with 08 size tube/coil. Two on/off valves offer a choice of 2-position, 3-way (SV09-23-02) or 2 position, 4-way (SV09-24-01).
Pneumatic tubing and fittings
New Nitra pneumatic tubing and fittings come in many sizes. Available in 100 and 250-ft lengths, Nitra 16-mm polyurethane tubing provides tight OD tolerance and has good kink resistance. Ether-based tubing provides hydrolysis, oil, and cold resistance.
Base controller
Versatile Base (VB) series of controllers is rated for 8 to 32 Vdc input power and temperatures from –40° to 80°C. Based on PLC on a Chip technology, it suits standard and custom I/O expander boards and is programmed with EZ Ladder software which supports ladder diagram with function block programming.
Load-position sensing cylinders
Electronic positioning transducer cylinders are available for hydraulic and pneumatic cylinders. Electronic load-position feedback is via magnetostrictive linear-displacement transducer. It features rod diameters from 5⁄8 to 4 in. and cylinder bores from 11⁄2 to 8.00 in.
Spring-biased shuttle valve
Miniature 375 spring-biased shuttle valve is ideal for system pressures to 5000 psi. Poppet in this 3⁄8-in. diameter shuttle valve is biased so emergency port is NC, and the normal and service ports are connected.
Air lubricators
Line of Mindman air units lubricates air tools, cylinders, valve, air motors, and other air-driven devices. They are available in port sizes from 1⁄8 to 11⁄2 in. and rated for pressures to 17.5 kgf/cm2 (1.75 MPa) and temperatures to 80°C.
Electronic foot pedal
PLUS+1-compliant KEP3 electronic foot pedal is a bi-directional, over-center rocker pedal that drives vehicles equipped with hydrostatic transmissions and/or electronically controlled engines. It delivers commands to the electronic transmission or the engine controller, where the output signal of the foot pedal is proportional to the angle of the foot pedal actuation.
Linear inductive position sensors
BIP linear inductive position sensor features absolute measuring for position monitoring in drive spindles and clamping devices for tools and workpieces. It is non-contact and detects linear travel to 40 mm, while offering resolution of 14 µm, high repeat accuracy of ±80 µm and non linearity of ±250 µm.
Hydraulic control valves
BG4D line of oil hydraulic directional control valves now includes a built-in relief valve. They are designed for heavy-duty applications where low internal leakage is important and are available with lever, cam, air and oil pilot operation for flows to 100 lpm (25 gpm).
