RADIUS Series A Pneumatic Actuator

The RADIUS Series A rack and pinion actuators are designed to operate “quarter-turn valves”. The wide torque range capabilities* ensure that Radius™ is more than suitable for plug, ball, butterfly valve and damper applications.

Features

• Wide torque range available.
• Namur accessory mounting surfaces are standard on all Radius actuators for attachment of ancillary control devices.
• Radius quality standards and support.
• High visibility two-part position indicator may have upper portion removed to expose external Namur drive shaft for simple attachment of Namur accessory devices while retaining position indicating capability.
• Complete o-ring sealing protects against ingress of outside moisture and contaminants.
• Unique travel stops in both open & close direction are standard on all models and independently and externally adjustable using standard tools.
• One piece anti-blow-out bottom entry drive shaft.
• Available in Spring Return (AS) and Double Acting (AD) confi gurations. Multiple spring design allows for a wider range of torque from a single  unit. All springs are self-contained and guided for optimum effi ciency. All models are fully convertible between
  double acting & spring return.
• Corrosion resistant by design. Exacting standards of corrosion protection render Radius suitable for most hostile environments.
• Low-cost, closed circuit breathing system available (Namur fi tting) to protect actuator internal parts from extremely corrosive environments.
