Manual Actuator

The SIMMEL 512 series declutch override gear box were specially designed used for butterfly valve, ball valve and plug valve together with pneumatic actuators.
This device allows for manual operation during installation, system testing and in the event of supply air-failure.
The SIMMEL 512 Series mount directly to many of the most popular rack and pinion style actuators on the market, and does not require a bracket between the pneumatic actuator and declutch override.
