This valve utilizes an electromagnetic directional valve to control the valve plate opening and closing using compressed air. In the event of a power outage or loss of compressed air, valves with a nominal diameter (DN) of 80 or below will automatically close using spring force. For DN100 and above, the valve utilizes a solenoid valve group and a check valve to quickly close the original air source pressure, ensuring rapid shut-off.<\/p>\n<p>This series includes two types of shaft seal structures: the GDQ-J-A with rubber seals and the GDQ-J-A(b) with bellows seals. The GDQ-J type features an angle passage design, while the GDQ-S type includes a three-way design with a pre-extraction port. These design variations make the valve suitable for diverse applications within vacuum systems.<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\"alignnone wp-image-6550 size-large\" src=\"https:\/\/test.nuoxutech.com\/wp-content\/uploads\/2024\/04\/newGDQnew-624x1024.jpg\" alt=\"\" width=\"624\" height=\"1024\" title=\"\" srcset=\"https:\/\/test.nuoxutech.com\/wp-content\/uploads\/2024\/04\/newGDQnew-624x1024.jpg 624w, https:\/\/test.nuoxutech.com\/wp-content\/uploads\/2024\/04\/newGDQnew-183x300.jpg 183w, https:\/\/test.nuoxutech.com\/wp-content\/uploads\/2024\/04\/newGDQnew-768x1261.jpg 768w, https:\/\/test.nuoxutech.com\/wp-content\/uploads\/2024\/04\/newGDQnew-935x1536.jpg 935w, https:\/\/test.nuoxutech.com\/wp-content\/uploads\/2024\/04\/newGDQnew-300x493.jpg 300w, https:\/\/test.nuoxutech.com\/wp-content\/uploads\/2024\/04\/newGDQnew-512x841.jpg 512w, https:\/\/test.nuoxutech.com\/wp-content\/uploads\/2024\/04\/newGDQnew.jpg 1039w\" sizes=\"(max-width: 624px) 100vw, 624px\" \/><\/p>\n<h3>Key Features:<\/h3>\n<ol>\n<li><strong>Automatic Closure:<\/strong> Ensures rapid shut-off using spring force for DN80 and below, and a solenoid valve group for DN100 and above, providing reliable operation during power or air supply failure.<\/li>\n<li><strong>Shaft Seal Options:<\/strong> Available with rubber seals (GDQ-J-A) or bellows seals (GDQ-J-A(b)) for enhanced flexibility and performance in different applications.<\/li>\n<li><strong>Design Variants:<\/strong> Includes angle passage (GDQ-J) and three-way design with a pre-extraction port (GDQ-S) to meet various system requirements.<\/li>\n<li><strong>Medium Compatibility:<\/strong> Suitable for air and non-corrosive gases, making it ideal for a wide range of vacuum applications.<\/li>\n<\/ol>\n<h3>Applications:<\/h3>\n<ul>\n<li>High vacuum systems in industrial processes<\/li>\n<li>Semiconductor manufacturing<\/li>\n<li>Pharmaceutical production<\/li>\n<li>Chemical research and processing<\/li>\n<li>General laboratory vacuum applications<\/li>\n<\/ul>\n<h3>Technical Specifications:<\/h3>\n<ul>\n<li><strong>Operation:<\/strong> Pneumatic with electromagnetic directional control<\/li>\n<li><strong>Automatic Closure:<\/strong> Spring force or solenoid valve group for rapid shut-off<\/li>\n<li><strong>Shaft Seal Options:<\/strong> Rubber seals (GDQ-J-A) or bellows seals (GDQ-J-A(b))<\/li>\n<li><strong>Design Variants:<\/strong> Angle passage (GDQ-J) and three-way design with pre-extraction port (GDQ-S)<\/li>\n<li><strong>Working Medium:<\/strong> Air and non-corrosive gases<\/li>\n<\/ul>\n<h3>Advantages:<\/h3>\n<ul>\n<li><strong>Reliable Shut-Off:<\/strong> Ensures rapid and automatic shut-off to protect vacuum systems.<\/li>\n<li><strong>Flexible Design:<\/strong> Multiple seal and design options to suit diverse applications.<\/li>\n<li><strong>Durable Construction:<\/strong> Engineered for long-term reliability and performance in demanding environments.<\/li>\n<li><strong>Versatile Application:<\/strong> Suitable for various industrial and research applications requiring high vacuum integrity.<\/li>\n<\/ul>\n<div dir=\"auto\">For more information about the <a href=\"https:\/\/www.test.nuoxutech.com\/gdq-j-a-pneumatic-high-vacuum-flapper-valve\/\" rel=\"nofollow sponsored\">GDQ<\/a>-J-A Pneumatic High Vacuum Flapper Valve, contact NuoXuTech<\/div>\n<div dir=\"auto\"><strong>Mail:<span style=\"color: #3366ff;\"><a style=\"color: #3366ff;\" href=\"mailto:contact@nuoxutech.com\" target=\"_blank\" rel=\"nofollow noopener sponsored\">contact@nuoxutech.com<\/a><\/span><\/strong><\/div>\n<div dir=\"auto\"><strong>WhatsApp: <span style=\"color: #3366ff;\"><a style=\"color: #3366ff;\" href=\"https:\/\/wa.me\/message\/Z6LWLVZDXHWFD1\" target=\"_blank\" rel=\"nofollow noopener\">+86 13849062209<\/a><\/span><\/strong><\/div>\n<div dir=\"auto\"><strong>Our team is ready to provide you with professional service and support.<\/strong><\/div>\n","protected":false},"excerpt":{"rendered":"<p>The GDQ-J-A Series Normally Closed Pneumatic High Vacuum Flapper Valve by NuoXuTech offers reliable and rapid shut-off in vacuum systems.
