Vatac Investment Casting are special designed for small sized Check valves and make the overview
more beautiful, also have the characteristic of big size
valves, leakage less than 100 ppm (parts per million) of volatile organic
compounds. 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 stem packing seal area and in the bonnet
gasket sealing area, 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 Investment Casting Check Valves meeting a maximum of 100 ppm VOC leakage prior to shipment.
