E type

Designed for operation of ball valves, butterfly valves, plug valves and other 90° turn devices.

  • Dual end stop adjustments, located outside of the pressurised cylinder, for open and closed position.
  • Double-acting range: from 90 to 1655 Nm (6 bar)
  • Sprint-return range: from 32 to 586 Nm (6 bar)
  • Temperature range: from -20 to +80°C (-4 to +176°F)
  • Integral body adaptor kit, which is interchangeable with a wide range of valves for direct mounting by using an interchangeable insert sleeve
  1. SPRINGS
    Springs are located inside the piston rack, same overall dimensions for DA and SR actuators
    No special tools required to change from DA to SR or opposite
    Long bolting is standard feature to fully relax springs
  2. PISTON WEAR PADS
    Dual encapsulated “POM” wear pads on the piston, prevent metal to metal contact between piston and cylinder, thus providing low friction travel
    The dual encapsulated “POM” wear pads absorb the adverse side loading at start of each stroke
  3. TWIN GUIDE BARS
    Twin guide bars absorb any adverse side loading, from rack at the start of each stroke, which reduces pinion and rack wear
  4. BACKUP BEARING
    Piston backup bearings, which are situated behind the pistons o-ring, ensure linear movement and prevent wear on the cylinder surface
  5. TRIPLE SHAFT BEARING
    Triple shaft bearing to prevent any adverse loading on the driveshaft
  6. DRIVESHAFT & CAM
    The shaft and adjustment cam are machined from solid bar material
    The cam mechanism allows for 2.5° overtravel in both directions
    The inner depth of the driveshaft allows for total engagement of any valve shaft height for direct mounting
  7. BODY ADAPTOR KIT
    Integral Body Adaptor Kit (BAK), interchangeable with a wide range of valves for direct mounting by using an interchangeable sleeve
    Dual End Stop Adjustment are integral to the body adaptor and operate in conjunction with the machined cam on a single piece driveshaft, remaining outside the pressurized cylinder
  8. INSERT SLEEVE
    Manufacture in stainless steel, can be rotated for cross or parallel mounting.
    The insert is held inside the driveshaft by means of a circlip
    Can be Square, Double D or Round with Key for direct mounting
