PneumaticValveActuation
Compact Actuators that ProvideReliableRemoteControl
Saunders EC and SSC Pneumatic Actuators facilitate remote operation of
the valve, as an integral part of a control system. Both are compact
piston style actuators with excellent chemical and temperature resistance.
The versatile and robust design derived from the use of high technology
materials of construction, results in an actuator suitable for a wide range
of process industry applications.

SSC
With the same flexibility as
the EC Actuator, the SSC
has beenmanufactured
with a 316C12 stainless
steel investment cast
housing. Suitable for both
aseptic and industrial
applications the SSC has
excellent resistance to
both chemical and
steam duties.
Size range DN8 – DN50
All three operation
modes, double acting,
spring to close and
spring to open feature
the same physical
dimensions for a given
valve size. This provides
uniform compact
envelope dimensions and
outstanding economic
benefits particularly for
spring return failsafe
actuation.
Field conversion of
manual valves to power
actuation is readily
achieved ‘in-line’ without
special tools or
modification.

EC
The EC is manufactured
by injectionmoulding
PES (polyethersulphone),
which has a temperature
range of -10° to +100°C
ambient (autoclave
maximum 150°C).
Actuators can be
supplied as spring close,
spring open or double
acting with various spring
pack options for a variety
of pressure requirements.
