Double-acting and spring-return hydraulic actuators for remote and local operation

of valves in on/off and modulating heavy-duty service. Available with output torques

up to 6.638.000 lb-in.

General Application

OLGA and OLGAS series hydraulic actuators are designed for the control of quarter-turn

ball, butterfly, plug or damper style valves.

Technical Data

Design pressure (MAWP)

OLGA/OLGAS: Up to 1500 psig (contact factory for PED limit)

OLGAS-QA: Contact Factory

Supply medium: Hydraulic oil, special version for fire-resistant fluids

Output torque

OLGA: Double-acting torque up to 6.638.000 lb-in

OLGAS: Spring starting torque up to 2.964.000 lb-in

Spring ending torque up to 2.079.000 lb-in

Ambient temperature

Standard range: -4 to +210 °F / -20 to +100 °C

Extended range: -70 to +275 °F / -60 to +135 °C

MAWP: Maximum Allowable Working Pressure is the pressure defined

for the design of the actuator pressure containing parts.

MOP: Maximum Operating Pressure is pressure that generates the

torque used to engineer the mechanical loaded parts of

the actuator and it is the one required to produce the design torque

of the actuator
