The RPSR Rotary Piston Spring Return Actuator is designed for heavy duty control applications that require optimum performance. The RPSR actuator is typically utilized when applications require the control valve to fail-open or fail- closed upon loss of power supply gas. The RPSR actuator incorporates a crank-arm mechanism specifically designed for the rigors of throttling control valve applications. The RPSR actuator can accept high pressure power supply gas up to 400 psig (2478 kPa) enabling the use of smaller actuators or BHGE’s exclusive Bleed to Pressure System (BPS*) feature.
