Pratt Industrial PV-140-SR10 Pneumatic Actuator, Spring Return Features:
- A single compact design utilizing identical body and end caps for both double acting and spring return models. This feature reduces inventory and allows field conversion, by adding or removing modular spring cartridges.
- Full conformance to following latest specifications: ISO 5211, DIN 3337 and VDI/ VDE 3845 for product interchangeability and easy mounting of solenoids, limit switches and other accessories.
- Pratt piston rack and pinion design for compact construction, symmetric mounting position, high-cycle life and fast operation. Reverse rotation can be accomplished in the field by simply inverting the pistons.
- Two independent external travel stop adjustments permit easy and precise adjustment of +/- 5° in both directions. This adjustment may be made in either the open or closed position and provides for accurate valve alignment.
- Multiple bearings and guides on pistons and racks for precise operation, low friction, high cycle life and a blowout proof pinion shaft.
- Electroless nickel-plated blowout resistant, bearing guided, one-piece pinion shaft for improved safety and maximum cycle life.
- High precision teeth on piston racks and pinion shaft for accurate positioning, low backlash, and maximum engagement resulting in overall efficient operation.
- Extruded aluminum body with both internal and external corrosion protections having a honed cylinder surface for longer life and a lower coefficient of friction.
-Modular preloaded spring cartridges designed with coated springs for simple range versatility, greater safety and corrosion resistance.
- Selected high quality bearings and seals that provide a wide operating temperature range, low friction, and high cycle life.
- Internal and external Stainless Steel fasteners for long term corrosion resistance.
- Multifunctional position indicator for visual position indication, and a direct, easy, economical way to mount popular sensors.
