Project Description

Diaphragm Actuators

KOMOTO® linear actuators are designed to control the flow, level and the pressure of fluid to respond to demand for fine process control and various plant systems. The 3600 actuators will satisfy customer’s needs with its high reliability, durability and performance.


The AO-3600 Diaphragm actuators has been designed to control accurately the flow and pressure of fluid in response to demand of fine process control as well as various plant systems. These actuators have been developed for powerful and high performance pneumatic actuating of linear motion valves as well as rotating valves.

  • Simple cost effective design
  • Long stroke and wide application
  • Strong seating force
  • Compact and light weight
