Actuators

EKK actuators are characterized by excellent actuating characteristics and durability due to a unique bearing and rubber diaphragm design. Besides on/off functionality with negative and positive pneumatic control EKK developed proportional actuators with an integrated position sensor for better controllability of your application.

Features

  • Controls the opening and closing of the wastegate valve to prevent the boost pressure in a turbo charger from exceeding maximum pressure.
  • The actuator can be used on, among other things, turbochargers with a downsized engine that are intended for improved fuel efficiency.

EKK actuators have excellent actuating characteristics and durability due to a unique bearing and rubber diaphragm design. Besides on/off functionality with negative and positive pneumatic control EKK developed proportional actuators with an integrated position sensor for better controllability of your application.

Highly durable material and surface treatment is applied to the rod and bearing, which means the surface is especially good with working in environments with high vibrations. EKK has several materials for the diaphragm and spring to cover operation temperature range. The high quality linkpin is made of special material with heat treatment to guarantee high abrasion resistance. The actuator is highly responsive in low temperatures. This actuator is equipped with a heat shield plate and high heat resistance bearing to guarantee optimal performance in severe temperatures.

  • Controls the opening/closing of the nozzle for turbochargers.
  • Adjusts the nozzle opening angle according to rotation level to improve high torque at low speed, fuel efficiency, and acceleration performance.
  • A heat shield plate and bush made of a highly heat-resistant material are used to guarantee better high-temperature operation endurance.
  • High responsiveness in low temperature.
