Series LS actuators readilty replace non-stainless diaphragm actuators and offer protection from corrosion in a smaller and lighter package

Options include
double acting,
spring push down, spring pull up, jackscrew manual override
and many others.

As with QTRCO Rack & Gear actuators, piston seals can be replaced while the actuator remains in place on the valve

When to consider QTRCO as a replacement / substitute to the diaphragm actuators:
-
Space / weight savings
-
All SS control package
-
High vibration or seismic application
-
Corrosion
-
'On-the-valve' maintenance
