Valve<\/h3><p>The internal flap of the flap check valve operates solely through the pressure of the fluid flowing in one direction, preventing reverse flow into the pump and avoiding potential damage. This valve functions entirely based on fluid pressure and contains no external control mechanism. Flow regulation inside the flap check valve is achieved by a disc that moves closer to or away from the sealing surface depending on the fluid pressure.<\/p><p>The flap check valve is widely used in systems where backflow must be prevented. Common applications include pumps, swimming pool and jacuzzi installations, residential plumbing systems, and the gas, oil, and petrochemical industries.<\/p>\t\t\n\t<\/div>\n<\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3d00a80 elementor-widget elementor-widget-spacer\" data-id=\"3d00a80\" data-element_type=\"widget\" id=\"03\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t            <\/div>\n        <\/div>\n                    <\/div>\n        <\/section>\n                <section class=\"elementor-section elementor-top-section elementor-element elementor-element-c5e9900 elementor-section-stretched elementor-section-content-middle elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"c5e9900\" data-element_type=\"section\" data-settings=\"{&quot;stretch_section&quot;:&quot;section-stretched&quot;}\">\n            \n                        <div class=\"elementor-container elementor-column-gap-extended \">\n                    <div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-ea719bd\" data-id=\"ea719bd\" data-element_type=\"column\">\n        <div class=\"elementor-widget-wrap elementor-element-populated\">\n                    \n                <section class=\"elementor-section elementor-inner-section elementor-element elementor-element-66a5169 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"66a5169\" data-element_type=\"section\">\n            \n                        <div class=\"elementor-container elementor-column-gap-default \">\n                    <div class=\"elementor-column elementor-col-100 elementor-inner-column elementor-element elementor-element-fba250e\" data-id=\"fba250e\" data-element_type=\"column\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n        <div class=\"elementor-widget-wrap elementor-element-populated\">\n                    \n        \t\t<div class=\"elementor-element elementor-element-7b2de3c elementor-widget elementor-widget-ct_heading\" data-id=\"7b2de3c\" data-element_type=\"widget\" data-widget_type=\"ct_heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"ct-heading h-align-center item-st-default\">\r\n\t    <h2 class=\"item--title case-animate-time st-default \" data-wow-delay=\"ms\">\r\n        <span class=\"slide-in-container\"><span class=\"d-inline-block wow case-fade-in-up\">Product<\/span><\/span> <span class=\"slide-in-container\"><span class=\"d-inline-block wow case-fade-in-up\">Sizing<\/span><\/span>    <\/h2>\r\n<\/div>\r\n\r\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t            <\/div>\n        <\/div>\n                    <\/div>\n        <\/section>\n                <section class=\"elementor-section elementor-inner-section elementor-element elementor-element-1e72613 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"1e72613\" data-element_type=\"section\">\n            \n                        <div class=\"elementor-container elementor-column-gap-default \">\n                    <div class=\"elementor-column elementor-col-100 elementor-inner-column elementor-element elementor-element-c2d2534\" data-id=\"c2d2534\" data-element_type=\"column\">\n        <div class=\"elementor-widget-wrap elementor-element-populated\">\n                    \n        \t\t<div class=\"elementor-element elementor-element-a5c12a9 elementor-widget__width-initial elementor-widget-mobile__width-inherit elementor-widget elementor-widget-text-editor\" data-id=\"a5c12a9\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<div class=\"table-responsive\">\n<table class=\"table-bordered\">\n<tbody>\n<tr style=\"background: #7388ac; color: #fff;\">\n<td><b>Product<\/b><\/td>\n<td><b>Size (mm)<\/b><\/td>\n<td><b>Quantity per Carton<\/b><\/td>\n<\/tr>\n<tr>\n<td>U-PVC Flap Check Valve<\/td>\n<td>50<\/td>\n<td>24<\/td>\n<\/tr>\n<tr>\n<td>U-PVC Flap Check Valve<\/td>\n<td>63<\/td>\n<td>16<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t            <\/div>\n        <\/div>\n                    <\/div>\n        <\/section>\n                    <\/div>\n        <\/div>\n                    <\/div>\n        <\/section>\n        \t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Specifications Product Application Product Sizing Flap Check Valve The flap check valve (also known as an automatic flap valve) is designed to allow fluid to flow in only one direction.
