The Hoke 7122 Series ball valves are compact quarter-turn instrumentation valves engineered for reliable shutoff performance in high-pressure gas and liquid systems. Part of the Ultramite™ 70 Series, these valves feature a floating ball design that provides bubble-tight sealing, low operating torque, and extended cycle life under repeated operation. The welded body construction improves structural integrity and prevents accidental disassembly during service. Reinforced seat materials and dual stem sealing systems ensure dependable leak-tight operation in both vacuum and pressure applications. Constructed primarily from 316 stainless steel, the series offers excellent corrosion resistance and compatibility with demanding industrial environments. Available with a variety of end connections and configurations, the valves are suitable for analyzer systems, sampling panels, hydraulic service, process instrumentation, and general isolation duties requiring compact and durable shutoff valves.
