Flanged Ball Valves AKH2
A two piece full port standard PFA lined ball valve which offers high safety factors, high stability, rigidity and eliminates a potential leak path. The full port design minimizes pressure losses and increases flow capacities thus reducing energy and pumping costs.
FLOWSERVE ATOMAC lined ball valves are engineered to include a free floating ball design which offers the following benefits: Low frictional coefficients resulting in low operating torques. Positive shut-off across the pressure range. Reduction of stem side loads eliminating potential leaks to atmosphere through the valve gland. A real anti blow-out stem design offers increased safety. Each lined ball valve has its anti-static device, which provides protection against potentially dangerous electrostatic discharges. Long life seats, large stem sealing area as well as the substantial middle flanges and the molded liner take care for a leak and trouble free valve and minimizes downtime and maintenance.
Due to the actuator mounting flanges design according to DIN EN ISO 5211, pneumatic, electric or hydraulic actuators can easily be fitted. A wide range of liner material can be selected from FEP, PFA, Tefzel, PP, PVDF as well as conductive PFA. Also available with a V-port ball for precise modulating control service or with C-ball available.
