AKH2 PFA Lined Ball Valve

Fully PFA lined ball valve

Flowserve Atomac PFA Lined Ball Valve

A two-piece full port standard PFA lined ball valve offers high safety factors, high stability, and 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 the 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 protects against potentially dangerous electrostatic discharges. Long-life seats, large stem sealing area as well as substantial middle flanges and the moulded liner take care of a leak and trouble-free valve and minimize 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 materials 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 a C-ball available.
