Overview

Section 1: Overview

1.1 Description and General Information

Figure 1

Bettis BHH series includes several balanced rotary actuators used for operation of

quarter-turn valve. The actuator is prepared for mounting of control equipment with

several different functions and combinations. For more information see our product data

sheets or contact our sales representative directly.

Long service life and functional reliability of hydraulic systems and their components are

dependent on correct handling, installation, maintenance and repair to ensure fault-free

operation. Instructions directly attached to the equipments (e.g. nominal pressure) must

be observed. The system must not be operated over the permissible operating range. For

detailed information, please refer to the nal specications to be submitted.

The customer is responsible for ensuring that these instructions are read and fully understood.

For personnel safety and safety of the equipment please read the Section 2 for Safety.

NOTE:

For technical data please refer to Product Data Sheets.
