<h2 data-section-id="fh0lno" data-start="488" data-end="534">What Is a High Vacuum Control Gate Valve?</h2>
<p data-start="535" data-end="859">A high vacuum control gate valve is designed to both <strong data-start="588" data-end="621">control pressure (throttling) and <strong data-start="626" data-end="653">isolate vacuum chambers within a system. Unlike standard valves, it operates in environments where pressure can drop to extremely low levels (as low as 10⁻⁸ mbar or lower), ensuring precise flow regulation and leak-tight sealing.

<p data-start="861" data-end="1077">For example, advanced models such as the <strong data-start="902" data-end="932">64.2 HV Control Gate Valve provide accurate pressure control using a movable gate plate that adjusts the valve opening dynamically.
