Output signal indicator - As an option the pneumatic actuator may be equipped with a manual output signal indicator. A pin indicates if the valve is opened or closed: - Pin is not visible = valve is closed: - Pin is visible = valve is open
Proximity switch - As an option a ‘Namur‘ proximity switch can be used to transmit the valve position. This is a common requirement in automated process plants.
Flow restrictor, manual - As an option a manual flow restrictor may be fitted. This limits the stroke of the actuator and hence the gas flow rate.
Adaptors - To make connections to other components WEH GmbH can offer an extensive range of adaptors. These adaptors simplify valve, hose, pipework and sensor installation.
