Hoke High-Cycle 7223D RotoBall® bi-directional ball valves feature a high performance Delta stem seal designed to extend their operating life to between 50,000 and 100,000 cycles, depending on system configuration, with leak-free performance. Maximum operating pressure is 345 barg (5000 psig) at 21oC (70oF) and operating temperature range is -54o to +204oC (-65o to +400oF). The valves offer high flow with a Cv of 3.4 in a 9.5mm (0.375in) orifice. This series of ball valves was developed to meet demanding high-cycle actuation applications for CNG stations, vehicle control systems, test stands and pilot plants. A choice of connection types and sizes is available, as well as the option of factory assembled electric or pneumatic actuators.
