Control Valve

XDV Control Valves covering pressure control and flow control valves, and 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 XDV stem packing seal area and in the bonnet gasket sealing area, ln-house testing procedure has been developed and is periodically performed to ensure that standard product design and manufacturing criteria consistently result in the XDV Control Valves meeting a maximum of 100 ppm voc leakage prior to shipment.
