| VALV-POWR® SERIES VPVL MODEL C DOUBLE-ACTING AND SPRING-RETURN RACK- AND-PINION COMPACT PNEUMATIC ACTUATORS VALV-POWR - VPVL double-opposed piston actuators combine the benefits of high cycle life, a rugged construction, and an extremely compact and symmetrical design with a unique range of features and options. They are specifically designed for fast efficient operation of ball, butterfly, and other rotary type valves. FEATURES Single-Source Responsibility 5 Valves,actuators,and accessories are designed to operate as a unit with the highest degree of compatibility. 5 Valves, actuators, and accessories can be supplied completely assembled to provide unit responsibility from a single source. Versatility 5 Modular designs with same body and end caps for double-acting and spring-return reduce inventory. Springs can be added in the field to convert double-acting to spring-return or for changes in supply pressure. 5 Failure direction can be easily reversed from spring-to-open or spring-to-close orientation simply by inverting the pistons. ■ Actuator to valve attachments comply with ISO 5211/1 and EN 12116. 5 Solenoid valve and accessory attachments comply with NAMUR VDI/VDE 3845. I A wide range of optional accessories and control devices that include limit switches, solenoid valves, and mechanical safety lockouts are available to satisfy virtually all automated valve requirements. 5 Several models of 180 degree VPVL's are optionally available. High Cycle Life a Bearings on all sliding and rotating moving parts to ensure long life. S Dual piston rack-and-pinion mechanism for simple construction, high cycle life, and constant torque. ■ Hard-anodized PTFE-coated extruded aluminum body with honed internal surface for strength and lower coefficient of friction. 5 Mechanically multi-guided aluminum pistons for precise movement, low friction, and high cycle life. | 5 Machined teeth on piston racks and pinions for excellent rack and pinion engagement and maximum efficiency. Corrosion Resistant 5 Hard-anodized PTFE-coated body, polyester-coated end caps, and epoxy-coated springs, along with internal and external stainless steel fasteners, provide corrosion resistance in a variety of difficult applications and environments. Reliability 5 Safety-contained multi-spring design with preloaded and heavy-duty coated springs for simpler range versatility, greater safety, and corrosion resistance. 5 External adjustable stops in both directions assure flexibility and accuracy when setting the valve in the open and closed positions. 5 As an added safety feature, the external adjustment screws are slotted.The slot will indicate the presence of internal pressure. Pressure will begin to vent before the adjustment screws are completely backed out of the actuator.
