The Vatac Cast Iron Swing Flex Check Valves are designed and manufactured to ensure low leakage to international standards, Extensive base line laboratory testing (static and cycle testing) has been performed establishing critical design parameters necessary to achieve low emission sealing in the Vatac Iron Check Valves, In-house testing procedure has been developed and is periodically performed to ensure that standard product design and manufacturing criteria consistently result in the Vatac cast iron check Valve meeting a maximum of leakage prior to shipment.
