The Hoke 7100L Series ball valves are compact quarter-turn instrumentation valves designed for low-pressure gas and liquid service applications requiring reliable shutoff and smooth operation. These valves feature a floating ball design that provides dependable sealing performance, low operating torque, and long cycle life under repeated operation. The compact body construction simplifies installation in instrumentation panels and confined system layouts, while reinforced seat materials ensure reliable leak-tight performance across a broad range of media. Hoke’s Dyna-Pak® stem sealing system minimizes leakage and reduces maintenance requirements during long-term service. Constructed primarily from 316 stainless steel, the series offers excellent corrosion resistance and compatibility with a wide variety of industrial fluids and gases. Typical applications include analyzer systems, sampling panels, laboratory equipment, pneumatic systems, and general instrumentation isolation duties.
