OverviewFeatures & BenefitsSpecificationsDatasheet & Resources
ASEPCO Weirless Radial-Diaphragm Actuators for Inline Valves, Pneumatic

Our pneumatic actuators are not spring loaded and are designed to withstand a few dings and drops. All actuators have a position indicating shaft that extends when the valve is open, allowing you to confirm the valves position with a quick glance.

The actuators contain as few O-rings and seals as possible, resulting in a very simple maintenance procedure. If you can fasten a tri-clamp, you can easily assemble and disassemble any ASEPCO valve for inspection or maintenance, and you can do it without tools!

A large number of options are available with these actuators, including switches, solenoids, regulators, dual-acting positioners, and your choice of fail open or closed.
