VALV-POWR® SERIES VPVL MODEL C DOUBLE …

1 A111-3EN 7/2011 VALV-POWR VPVL DOUBLE -opposed piston actuatorscombine the benefits of high cycle life, a rugged con-struction, and an extremely compact and symmetricaldesign with a unique range of features and are specifically designed for fast efficient opera-tion of ball, butterfly, and other rotary type Responsibility Valves, actuators, and accessories are designed to oper-ate as a unit with the highest degree of compatibility. Valves, actuators, and accessories can be suppliedcompletely assembled to provide unit responsibilityfrom a single Modular designs with same body and end caps fordouble-acting and spring-return reduce can be added in the field to convert DOUBLE -acting to spring-return or for changes in supply pressure.

2 Failure direction can be easily reversed from spring-to-open or spring-to-close orientation simply byinverting the pistons. Actuator to valve attachments comply with ISO 5211. Solenoid valve and accessory attachments complywith NAMUR VDI/VDE 3845. A wide range of optional accessories and controldevices that include limit switches, solenoid valves,and mechanical safety lockouts are available to satisfyvirtually all automated valve requirements. Several models of 180 degree VPVL s are Cycle Life Bearings on all sliding and rotating moving parts toensure long life.

3 Dual piston rack-and-pinion mechanism for simpleconstruction, high cycle life, and constant torque. Hard-anodized PTFE-coated extruded aluminumbody with honed internal surface for strength andlower coefficient of friction. Mechanically multi-guided aluminum pistons forprecise movement, low friction, and high cycle life. Machined teeth on piston racks and pinions forexcellent rack and pinion engagement and maximumefficiency.
