LAG (Double Acting) - LAGS Series (Single Acting)

INTRODUCTION
DVG Automation “LA” linear actuator series are compact in design and are suitable to operate every type of linear valve either in modulating or heavy-duty services.
OPERATING RANGE
Pneumatic operating pressure for the LA pneumatic series ranges between 2 barg (35 psig) to 12 barg (175 psig) Standard design construction allows operating temperature from -30 degC (-22 degF) to +100 degC (+212 degF) Low temperature design extends operating range down to -60 degC (-76 degF) Supply medium: Instrument air, nitrogen, sweet gas. Special version available for sour gas Hydraulic operating pressure for the LA hydraulic Series ranges between 20 barg (290 psig) to 350 barg (5.000 psig) Standard design construction allows operating temperature from -30 degC (-22 degF) to +100 degC (+212 degF) Low temperature option extends operating range down to -60 degC (-76 degF) Supply medium: Hydraulic oil mineral based (standard). Special versions are available for fire-resistant or water based fluids Pneumatic High Pressure, Gas Over Oil and Electric Hydraulic are also available
