Actuator Main Options

MHP Hydraulic Manual Override

The MHP hydraulic manual override is used to manually operate the actuator in lack of air supply. It also allows to accurately adjust the actuator operating times, independently in opening and in closing, by way of the hydraulic regulators which work on the oil flow from one chamber to the other of the hydraulic cylinder during pneumatic operation. Moreover, it permits a smooth angular speed all along the stroke.

MHW Manual Handwheel

The handwheel manual override is mounted on the end flange of the pneumatic cylinder and consists of a jackscrew which is screwed into the bronze screw nut mounted in the cylinder end flange.

Mounting Interface

The mounting interface is customizable according to the valve top mounting and control accessories requirements.

Accessories

Biffi linear valve actuators can be supplied as a basic actuator or can be configured with various control accessories and related features.
