1.1 Intended use
Richter Twin Piston Quarter-turn Actuators,
series RA serve for the automatisation of
Richter ball and butterfly valves.
They satisfy the high quality requirements of the
chemical and industrial process engineering.
Fields of application:
pneumatic remote actuation of rotary valves
flow control in conjunction with appropriate control
valves and mounted positioners
If the actuator is intended for operating data other than
those intended, the customer must carefully examine
whether the design of the valve, accessories and ma-
terials are suitable for the new application (consult the
manufacturer).
