Vatac Globe 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 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 Globe Control Valves meeting a maximum of 100 ppm VOC leakage prior to shipment. Vatac Cast Steel Gate Valves are with main Features as below: » Size Ranges: 1/2” through 24” » Pressure Ratings: ANSI #150 to 1500 » Standards compliance: BS1873, ASME B16.34 or equivalents » Materials: Cast Carbon Steel, Cast Stainless Steel, Cast Duplex or Other Specials » Ends Connections: Flanged(FF, RF, RTJ) to international standards » OS&Y, Outside Stem and Yoke » Metal-sealed(API Trim # 1, #5, #8, #10 and etc.) » Optional Locking Device or Stem Extension » Optional Direct Mounting to ISO 5211 » Self-operated, Pneumatic and Electric » Reduce Port
