Swagelok medium-pressure ball valve provides leak-tight seal

The Swagelok FKB series medium-pressure ball valve provides a leak-tight seal for applications up to 15 000 psig (1034 bar). The trunnion-style ball valve features the company's patent-pending direct load design, which delivers a more consistent seal across a full range of pressures. Innovative stem and end connection seals prevent shell leakage and provide robust cycle life even in severe conditions.

The new ball valve expands the company's line of medium-pressure products, including gaugeable tube and adapter fittings and seamless tubing.

"With the patent-pending direct load design, the medium-pressure ball valve delivers a consistent leak-tight, live-loaded seat seal across a full range of pressures," said Bill Menz, market manager at Swagelok. "Even when depressurisation of the system occurs, the direct load design ensures a leak-tight seal upon repressurisation of the system."

The valve features low-torque actuation, eliminating the need for assist methods and accessories in manual actuation. If pneumatic actuation is required, the valves are available with ISO-5211 compliant actuators. A positionable handle provides flexibility in panel layout by reducing clearance issues with other components.

The valve also has a 0.209in (5.3mm) orifice, 316 stainless steel body construction, and reinforced PEEK seat seals. The valves are rated for temperatures from 0° to 250°F (-17° to 121°C) and maintain a full pressure rating throughout the entire operating temperature range. Multiple O-ring materials are available, including nitrile, fluoroelastomer, and perfluoroelastomer.
