 |
| Compact Design |
| The TECHNICA 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. |
| |
| Namur Mounting |
| Namur VDI/VDE 3845 and ISO 5211 dimensions on all sizes. No special blocks are required to mount solenoid valves, limit switches or positioners. |
| |
|
|
 |
| Degree of Travel |
| The standard angle of rotation is 90°. Additional travel rotations of 120°, 135°, 150° and 180° are available. For sizes from UT16 and larger, TECHNICA features dual travel stops that provide for ± 10° stroke registration on both the opening and closing phases of the actuator stroke. 110° of travel in a standard 90° actuator! |
| |
| Bottom Mounting Flange |
| The “patent pending” bottom plate design, unique to TECHNICA, secures a captive pinion (anti-blowout system) and permits flexibility in mounting by retaining AISI 304 nuts (standard) or AISI 304 bolts (optional) in either dual ISO patterns, or to customer dimensions. |
| |
| Flexible Output Shafts |
| 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. |
| |
| High Cycle Bearings |
| 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. |
| |
| Rugged Tooth Design |
| The pinion teeth are engaged the full length and stroke of the piston. The pinion height allows manual override without disturbing the indicated positions. |
| |
| High Visibility Position Indication |
| External open/close indicator as standard, available for all the rotations. |
| |
| Working Temperature |
Standard working temperature range of Buna seals -20°C to 80°C (-4°F to 176°F).
Low Temperature
Low temperature with Silicone seals -48°C (-55°F)
High temperature with Viton seals to 121°C (250°F); 149°C (300°F) cyclic |
| |
| High Cycle Life Wear Pads |
| Pistons incorporate double wear pads to separate the rack from the actuator wall and serve as both guide and wear bearings. |
| |
| Pre-Loaded Spring Cartridges |
| 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. |
| |
| Alternative Operating Media |
| Air pressure operation from 2 to 10 Bar (40 – 150 PSI). Water, nitrogen and compatible hydraulic fluids may also be used to power the actuator. |
| |
| Stainless Steel Fasteners |
| All external fasteners are corrosion resistant stainless steel. |
| |
| Honed Bore for High Cycle Life |
| Extruded aluminum body is internally machined and lapped 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 with non-silicone grease. |
| |
| Traceability |
| All units are externally stamped with a progressive traceable serial number. |
| |
| Quality Assurance |
| 100% of all units are factory pressure and leak tested, and individually boxed for shipment. |
