Highlights include a 316 stainless steel body to combat hydrogen embrittlement, a reduced leak rate and a higher operational pressure range. These features mean excellent suitability for Proton Exchange Membrane (PEM) fuel cell systems or Alkaline Fuel Cell (AFC) systems utilising either an active or passive recirculation loop.<\/p>\n\n\n\n<p>Furthermore, along with IP65 cable plugs, both valves are available with IP6K9K electrical connections, ideal for automotive applications. In terms of process integration, each valve can be supplied with either a threaded, flange or cartridge process connection to help with system integration.<\/p>\n\n\n\n<p>For customers looking to mount solenoid valves on manifolds for mass production, the design has been optimised to speed up installation with fewer larger mounting holes and no need to remove the coil, reducing the number of manufacturing steps, expediting installation. Three coil sizes are offered, with or without ATEX and IEC EX certification.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><a href=\"https:\/\/www.engineernewsnetwork.com\/blog\/wp-content\/uploads\/2024\/02\/image003.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"459\" height=\"496\" src=\"https:\/\/www.engineernewsnetwork.com\/blog\/wp-content\/uploads\/2024\/02\/image003.jpg\" alt=\"\" class=\"wp-image-27266\" srcset=\"https:\/\/www.engineernewsnetwork.com\/blog\/wp-content\/uploads\/2024\/02\/image003.jpg 459w, https:\/\/www.engineernewsnetwork.com\/blog\/wp-content\/uploads\/2024\/02\/image003-278x300.jpg 278w\" sizes=\"auto, (max-width: 459px) 100vw, 459px\" \/><\/a><figcaption class=\"wp-element-caption\">Burkert\u2019s Type 6440 safety shut-off valve is ideal for PEM and AFC systems<\/figcaption><\/figure>\n<\/div>\n\n\n<p><strong>Providing safe shut-off<\/strong><\/p>\n\n\n\n<p>The Type 6440 is a servo-assisted 2-way piston valve that provides safe shut-off without using fluid pressure. This allows it to support pressures up to 40 barg (PN40) and larger orifice sizes for higher flow rates and less pressure drop. An EPDM seal and a high seat tightness ensure a low leakage rate of 10-4mbar l\/sec, while the valve has a media temperature range from -40\u00b0C up to 120\u00b0C.<\/p>\n\n\n\n<p>Maximum ambient temperature ratings reach up to 75\u00b0C and 85\u00b0C for stationary power and mobile power applications, respectively. The Type 6440 is available in DN6, DN8 and DN12 sizes, covering a wide range of applications. Operators looking to save energy can also specify the Type 6440 with Kick &amp; Drop coils. In this double coil design, a high electrical impulse opens the valve, and 500 milliseconds later, it switches to a power saving mode, greatly reducing energy consumption.<\/p>\n\n\n\n<p><strong>Accurate control for fuel cell performance<\/strong><\/p>\n\n\n\n<p>A direct acting proportional control valve, the Type 6020 optimises the performance and efficiency of fuel cells by regulating hydrogen supply to the stack. Suitable for closed control loops, with automatic setpoints for flow or pressure, fine control can be achieved thanks to the large setting range of 1:100.&nbsp;<\/p>\n\n\n\n<p>Designed to withstand a differential pressure of 25barg (PN25), it also has an elastomer seal allowing for a tight shut-off. Media temperature ranges from -40\u00b0C to 90\u00b0C with an EPDM seal, with ambient temperatures of up to 85\u00b0C are supported depending on coil selection. Sizes are available from DN2.5 to DN8.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><a href=\"https:\/\/www.engineernewsnetwork.com\/blog\/wp-content\/uploads\/2024\/02\/image005.png\"><img loading=\"lazy\" decoding=\"async\" width=\"208\" height=\"227\" src=\"https:\/\/www.engineernewsnetwork.com\/blog\/wp-content\/uploads\/2024\/02\/image005.png\" alt=\"\" class=\"wp-image-27267\"\/><\/a><figcaption class=\"wp-element-caption\"> The Type 6020 proportional control valve can be quickly installed, saving time for OEMs<\/figcaption><\/figure>\n<\/div>\n\n\n<p><strong>Full system support in-house<\/strong><\/p>\n\n\n\n<p>As a flow control specialist, B\u00fcrkert can provide its customers with complete system solutions under a single part number.
