Go to Image BankPneumatic ROP-series actuators are used mainly with the OMEGA Compact 3-way Rotary Control Valves for turning the slide to open or close ports A or B. These actuators can also be used with Frese Butterfly Valves.
The double acting actuator operates in both directions using air pressure on both sides of the piston.
The single acting actuator uses air pressure on one side only to move the piston in the desired direction and the spring on the other side of the piston will place the valve slide in open or close position when the air pressure is decreased or removed.
The spring in the single acting actuator will move the valve slide clockwise or the opposite direction depending on the location of the spring in the actuator.
If a handwheel is needed a Declutchable Manual Gear. Override will be used.
ROP-series actuators are designed in accordance with the latest international standards and regulations to achieve a higher performance.
ROP-series pneumatic actuators designed and manufactured according to ISO9001.
All actuators are pressure and leak tested and externally marked with dedicated serial number for traceability.
Fully compliant with the latest international standards including ISO5211, DIN3337 and VDI/VDE3845.
Fully compliant with NUMAR standard and convenient to replace or mount accessories including solenoid valves, limit switches and all types of the brackets for the EPR positioners.
