Description:
The RPDA Rotary Piston Double Acting Actuator is designed for heavy duty control applications that require optimum performance. The RPDA is typically utilized when applications require a "lock last" failure mode. The RPDA incorporates a “crank-arm” mechanism specifically designed for the rigors of throttling control valve applications. The RPDA can accept high pressure power supply gas up to 500 psig (3447 kPa) enabling the use of smaller actuators or Becker’s exclusive Bleed to Pressure System (BPS) feature.

Description:
The RPSR Rotary Piston Spring Return Actuator is designed for heavy duty control applications the require optimum performance. The RPSR is typically utilized when applications require the control valve to “fail open” or “fail closed” upon loss of power supply gas. The RPSR incorporates a “crank-arm” mechanism specifically designed for the rigors of throttling control valve applications. The RPSR can accept high pressure power supply gas up to 500 psig (3447 kPa) enabling the use of smaller actuators or Becker’s exclusive Bleed to Pressure System (BPS) feature.

Heavy Duty Double Acting Ball Valve Systems
Valve sizes from ¼” to 3”
140 in.lbs to 800 in.lbs
Spring Return Valve operators
Single acting with spring close or open
Valve Operator Systems
Spring Return operators are formed by bolting a spring return unit to a double acting Val-U-Act operator. The return movement is effected by a clock-type spring which is pretensioned to about half the operator torque. The amount of pretention is large, compared to the rotation and therefore the torque does not vary more than 20% over the rotation.
Spring returns are factory-installed and adjusted. The spring returns have a worm drive adjustment for setting or changing spring pretension. By inserting a socket key into one end of the worm the spring pretension can be very easily increased or decreased to suit operating conditions. To increase pretension, turn the worm clockwise; to decrease, turn counterclockwise.

The Morin Partial Stroke Test Device (PSTD) was developed to allow users to test emergency shut-down valves without disrupting the process. The PSTD unit is locked out when the unit is in service and the valve functions normally. When the unit needs to be tested, the operator unlocks the device and inserts the stop pin, allowing for 15 degrees of valve travel to sufficiently test the valve package. Unlike electronic versions, you are guaranteed a hard stop and no over-travel, time after time, without any special calibration.

What makes SOMAS actuators so special? One reason is that they have been specially designed to cope with the requirements of the process industry for reliable operation and precise control. Our actuators are mainly intended for use with SOMAS valves , but they can be easily adapted for use with other valves demanding a 90 degree arc of operation.
We have spared no effort in order to eliminate any backlash between the moving parts of the actuator or between the actuator and the valve. This has created the neccessary prerequisites for pinpoint precision and has laid the foundation for accurate diagnostics.
