Luobai manufactures a wide assortment of adapters – including hard-to-find sizes. Produced in sintered carbon steel, stainless steel, and from stainless bar stock, you are sure to locate an adapter which meets your need.
The Luobai rack & pinion pneumatic actuator produces linear torque output in a compact design utilizing the same body and end caps for double-acting and spring-return units.
The standard angle of rotation is 90°. Luobai actuators feature dual travel stops that provide ± 10° stroke rotation on both the opening and closing phases of the actuator stroke. 110° of travel in a standard 90° actuator!
Extruded aluminum body is internally machined and honed to exact specifications. Honing prevents dry spots from forming within the actuator bore and therefore eliminates premature seal failure—a critical aspect to long cycle-life. All internal and external surfaces are hard anodized for corrosion resistance, with all units permanently lubricated at the factory.
Shaft bearings isolate the pinion gear from the housing and support the shaft for high-cycle applications. Many competitive manufacturers do not provide this critical feature.
The pinion teeth are engaged the full length and stroke of the piston, and designed for the toughest flow conditions. The pinion height allows manual override without needing to remove the indicator.
The female pinion drive is standard with a double-square output drive, and optional with a double-D drive, keyed drive and designs to meet your specific requirements.
Epoxy-coated special steel springs are pre-loaded with non- metallic materials. The stainless steel end-cap fasteners are extra-long to allow for spring relaxation. All parts are corrosion-resistant.
Luobai offers a wide range of adapters for many different types of valves—including butterfly valves, ball valves and plug valves—as well as a variety of pneumatic and electric automation accessories suitable for diverse industrial environments.
