Key Features

Key features and benefits of Biffi RPD/RPS Low Pressure Actuators
1

Key Features

The actuators are enclosed in a weatherproof, carbon steel housing, which ensures durability and long-lasting performance even in harsh environments. This protects internal components from damage caused by moisture, dust, or debris, making the actuators suitable for outdoor and industrial use.
2

Key Features

These actuators provide consistent torque throughout their entire 90° stroke, ensuring reliable operation across all phases of movement. This feature is crucial for maintaining the proper function of valves or dampers without variations in power or performance.
3

Key Features

The electroless nickel-plated cylinders offer excellent resistance to corrosion, reducing wear and tear from exposure to aggressive substances. This ensures the actuators remain efficient over time, especially in corrosive or offshore environments.
