It is used to\u00a0control the flow of gas between the casing annulus and t he tubing at valve\u00a0depth. The valve has a check dart controlled by a spring which does not\u00a0allow the back flow of gas or well fluids. If the injection gas pressure in\u00a0casing &amp; tubing annulus at valve depth falls below the fluid tubing pressure,\u00a0the fluid from tubing will try to flow back through the valve. Reverse flow\u00a0through the valve is prevented by a check dart in the valve body. The check\u00a0dart is closed by pressure from the tubing and will not allow passage of fluid\u00a0until casing pressure is greater or equal than tubing pressure. This valve is\u00a0available from 1\/8&#8243; to 3\/8&#8243; port sizes in 1\/16&#8243; increments.<\/p>\n<p><strong>BENEFITS OF DESIGN PRINCIPLE<\/strong><\/p>\n<ul>\n<li>CV values for each orifice size are determined with ISA procedures to provide\u00a0accurate sizing for proper injection rates<\/li>\n<li>Efficiency of back check valve provides large flow capacities.
