Wedge Rock RS
Electric Actuator Driven Mechanical Spring Return Operator. Based on industry accepted rack and pinion frame, planetary stacks to provide required mechanical advantage from input, and helical compression springs, we added our patented Poly Lock to protect actuator from back-driving. The RS passively holds spring force and valve in normal position until a failed condition signal releases spring energy, which acts on the rack, moving the valve to the fail position – speed controlled by an adjustable damper.
