DOUBLE-ACTING PNEUMATIC ACTUATOR

Features

  • Double-acting pneumatic actuator (air–air), HTD series
  • 14 sizes: from HTD-032 to HTD-270
  • Torque tables for working pressures from 2 to 8 bar
  • Mounting flange according to ISO 5211 (F03 – F16)
  • NAMUR interface for the solenoid valve
Details – technical data

Operating principle

Air to port A forces the pistons outwards, so the pinion turns counter-clockwise while air is exhausted through port B.

Air to port B forces the pistons inwards, so the pinion turns clockwise while air is exhausted through port A.

Actuator sizing example

Valve torque 100 Nm + 30 % safety factor = 130 Nm. Minimum operating pressure is 6 bar (87 psig). In the 6 bar column, the first value above 130 Nm is 136.4 Nm, so the right model is HTD-092.

Double-acting actuator torque

For each model, the upper row is torque in Nm and the lower row in in-lb.

Single-acting spring return pneumatic actuator HTS

Features

  • Single-acting spring return pneumatic actuator, HTS series
  • Sets of 5 to 12 springs
  • Mounting variants A – D, for CCW or CW operation
  • Mounting flange according to ISO 5211
Details – technical data

Operating principle

Air to port A forces the pistons outwards and compresses the springs. The pinion turns counter-clockwise while air is exhausted through port B.

On loss of air pressure at port A, the stored energy of the springs forces the pistons inwards. The pinion turns clockwise while air is exhausted through port A.

Mounting variants and spring arrangement

Actuator sizing example

Valve torque 60 Nm + 30 % safety factor = 78 Nm. Minimum operating pressure is 6 bar (87 psig). The selected actuator is HTS-105-12, which delivers the following output torques:

  • air torque at 0° (valve closed) = 124 Nm > 78 Nm
  • air torque at 90° (valve open) = 84 Nm > 78 Nm
  • spring torque at 90° (valve open) = 120 Nm > 78 Nm
  • spring torque at 0° (valve closed) = 80 Nm > 78 Nm

Spring return actuator torque (Nm)

Spring torque and air output torque for each model and spring set.
