Technology & Features

The THERMAQUA® Actuators guarantee precise and reliable temperature control with many advantageous features:

• Easy to assemble with the ‘First-Open’ and ‘Click’ functions
  The integrated ‘First-Open’ function allows easy assembly of the THERMAQUA® Actuator.
  The lock maintains the actuator in an open position, allowing mounting to the valve with minimal effort. Upon commissioning, the lock is removed leaving the actuator ready for operation
  ‘Click’ function Actuators can be optionally fitted with the click feature where upon assembly; the adapter is screwed onto the valve leaving the actuator locked in place

Principles of operation

Designed for normally closed control valves, THERMAQUA® Actuators perform various control and regulation tasks as a two-step actuator (open/ close). The wax element is heated electrically by the applied operating voltage and silently opens the valve.

Without any operating voltage the wax element is no longer heated and the actuator closes (see time-stroke diagram). THERMAQUA® Actuators also allow for instant functionality checks of the device.
