Linear Valve Actuators

WHAT IS A LINEAR VALVE ACTUATOR
A linear valve actuator is a mechanical device that converts electric, hydraulic, or pneumatic energy into linear motion. This allows for greater efficiency in work as well as a cost-effective alternative to human operation.
Designed and manufactured to operate a variety of rising stem valves, linear actuators are customized to fit the customer’s requirements for a variety or markets and applications. Along with a wide range of construction types, we offer a large selection of standard and optional integrated controls and accessories.
