RL 147 POSITIONING RELAY
DESCRIPTION
The RL 147 Positioning Relay is a compact pneumatic device
designed to provide positive positioning of a pneumatic valve
or damper actuator. The positioner provides supply air
pressure against the actuator diaphragm to initiate stem or
shaft movement. The actuator spring reverses the stem or
shaft movement.
FEATURES
•
Rapid response
•
Good repeatability
•
Adjustable start point pressure
•
Adjustable span
•
Low air consumption
