* The valves can be used down to -10°C
All pressures are gauge pressures.
Bleed hole in the actuator
To bleed the control medium, the pneumatic actuator has a bleed hole that is located on the side of the actuator housing (con-
trol function normally closed). In certain areas of application (e.g. the foodstuff industry), dirty water or cleaning media could
enter through this bleed hole and penetrate the actuator, thereby adversely affecting correct operation. A special bleed system
with lip check valve is available for these applications, which prevents such functional impairment. The bleed hole at the side
is then closed.
