Meet Viper:
 Compact Design. Precise Control.
Demand-Based Power.

The Viper Series electric actuators deliver precise, reliable actuation for demanding industrial valve service.

Designed for both modulating and on-off operation, Viper handles linear motion requirements with a compact design, zero emissions, and minimal maintenance.

Viper combines proven mechanical design with flexible control configurations to meet diverse operating needs. BLAC INC.’s patented hydraulic actuator cylinder rod seal helps prevent contamination of internal drive cylinder components, supporting long-term reliability and performance.

Larger actuator sizes use an externally controlled, bi-directional electric motor to drive the linear output cylinder, providing zero-backlash operation when reversing direction. Smaller sizes incorporate on-board controls for precise motor speed and position management, delivering responsive, accurate control in a compact package.
