Linear Valve Actuators

Overview

PNL and HYL-Series high performance pneumatic and hydraulic linear valve actuators have been designed to automate any linear valve or mechanism. Using the same cylinder components as used for PN and HY-Series quarter-turn scotch-yoke valve actuators, long cycle life is guaranteed even in the most demanding applications and environmental conditions.

Applications

Automation of wedge gate, expanding gate, through conduit, globe, knife gate, swing check, lift and turn ball valves and all rising stem valves, and dampers.
