APPLICATIONS 18 HYDRAULICS & PNEUMATICS June 2023 www.hpmag.co.uk With a low maximum operating temperature, the new Kick and Drop coils from Bürkert are said to enhance safety and remove the potential of electrical overheating. The 3-in-1 design, covering various voltage inputs, also streamlines inventory management. The coils can also be used across a range of Bürkert solenoid valves, including pneumatic, plunger, servodiaphragm, and servo-piston, as replacement demand or retrofit. Covering a variety of inrush and holding powers, each 3-in-1 coil covers DC, AC 50Hz and AC 60Hz, spanning 24V to 240V inputs, this flexibility reduces storage and handling requirements. Energy efficiency The device optimises energy efficiency by utilising a high initial voltage to move the valve into position. After just 500ms, the New coil technology for solenoid valves can increase energy efficiency by up to 80% Kick and Drop valve coils from Bürkert are saving significant costs by reducing energy use and extending service life according to the manufacturer. The increased efficiency also optimises environmental sustainability. With a low maximum operating temperature, the coils are said to enhance safety and remove the potential of electrical overheating. The 3-in-1 design, covering various voltage inputs, and also streamlines inventory management. H&P takes a closer look. desired position is reached, and the coil wattage is reduced to a lower level that holds the valve position. This makes the coils well-suited to applications with long duty cycles. The increased ‘kick’ force is also useful for applications where the valve is required to open against a high-pressure differential. The design includes two coil windings encapsulated in a single epoxy coil, with both coils powered in series. The first winding delivers the ‘kick’ that moves the plunger, while the second winding ensures the ‘drop’, and holds the plunger in position. The overexcited inrush winding generates a very high starting power, creating a strong magnetic field using 85% power Kick and Drop coils can minimise the overall energy demand by up to 80% The design includes two coil windings encapsulated in a single epoxy coil, with both coils powered in series
