Electrostatic Charge

An electrostatic charge risk is present on the actuator surface; in case of cleaning,

use only antistatic cloth; in case of maintenance, avoid all rubbing/frictions that could

electrostatically charge the equipment.

Noise Emission

The verification of the noise of the actuated valve is at valve maker care.

The actuator’s noise can be considered negligible since it is an equipment for regular

on/off or intermittent use. If the integral quick exhaust valve is present, we

recommend using ear Personal Protective Equipment (PPE) to avoid any possible

acoustic discomfort.

The above mentioned accessories are operated by the actuator drive sleeve. The housing of the scotch

yoke mechanism has a flange with threaded holes to fix the actuator to the valve either

directly or, if required, with the interposition of an adaptor flange or a mounting

bracket. The actuator yoke has a hole with keyways suitable for the assembly of an

insert bush the internal hole of which is machined (by Biffi or at customer care),

according to the shape and dimensions of the valve stem. Biffi can supply different

types of control system following customer’s requirements.
