This element\u2014often a ball, cone, diaphragm, or flap\u2014is pushed aside or back against the resistance of a light spring or solely by the flow force. The path is clear and the medium can pass through the valve unobstructed.<\/p>\n<p><span style=\"font-size: 30px; letter-spacing: 0em;\">Buy a check valve from LiquoSystems<\/span><\/p>\n<p>Buy rust-free check valves from LiquoSystems for your water installation.
