| Description:
The
Becker RP Series (Rotary Piston Double Acting) Actuator utilizes
pressurized natural gas to provides the muscle to motivate ball type control
valves. The RPDA utilizes a high pressure pneumatic piston and crank-arm
design specifically suited for control valve modulation. The RPDA is capable
of throttling ball type control valves up to 42� bore (600 ANSI). The
RPDA Series actuator may be utilized for on-off actuation or for precise
regulation of natural gas pipelines. The Becker RPDA Series actuators
may be supplied as a complete control valve package or for retrofit to
customers� existing quarter-turn valves.
