Key Features

Key features and benefits of Biffi ALGA/ALGAS/ALGAS-QA Low Pressure Actuators
1

Key Features

The actuator's housing is entirely enclosed and designed to be weatherproof, made from carbon steel. This construction ensures the unit is protected from environmental conditions while offering maximum strength and durability.
2

Key Features

The actuator is equipped with a guide bar that provides resistance against transverse loads. This feature is essential for maintaining stability and ensures the piston rod is properly supported during operation.
3

Key Features

The piston rod is manufactured from hard chromium-plated alloy steel. This material not only offers excellent corrosion protection but also reduces friction, contributing to a more efficient and longer-lasting performance.
