Cast Check Valve

Fangwen Vango Valves Manufacture is one of the best China cast check valve manufactures and suppliers, as a company, our professional factory can always produce cast check valve products at both good quality and price.

Fangwen Cast Check Valves are designed and manufactured to ensure leakage of 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 Fangwen 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 Fangwen Cast Check Valve meeting a maximum of 100 ppm VOC leakage prior to shipment.
