for on-off or regulating of ball valves, plug valves and dampers.
The best solution when you are looking for electric actuators with
spring return and manual override.
RCE-SR for Safety and Accuracy
is an Electric Spring Return actuator with Spring to Open or Spring to
Close function when the electricity is shut off, either from
control room or by an accident. The RCE-SR series is available for
normal applications and applications in Hazardous Areas.
The RCE-SR actuators are used for safety function of ball or butterfly
valves in for example Oil Pipe Line applications. By switching the
signal to emergency mode or by a power failure the Spring Return
function will operate the valve to the decided safety position open or
Tank filling with high capacity and high accuracy
RCE-SR actuators with dosing function are used for applications at tank
farms and filling stations for tank wagons, oil & petrol distribution
trucks and bunker ships.
The RCE-SR actuator keeps the valve fully 100% open during the quick
filling. When the tank wagon, truck or ship is almost full, a control
signal is sent to the RCE-SR, which closes the valve down to a decided
dosing position, maybe 10% open. Now the flow is very low and the top
filling is made very accurate.
This way the tank farms and filling stations have quick filling with
increased delivery capacity and the best accuracy.
oil filling station for distribution trucks equipped with RCE-SR
actuators has a filling capacity for each valve of 1800 litres/minute
and still the top filling is within 1 Litre margin.
an emergency shut down or a loss of power when the valve is fully open
and the flow is 1800 litres/minute, the RCE-SR will close the valve so
quick that only 32 litres goes through the valve after the emergency
Fire dampers with reliable emergency function
RCE-SR actuators equipped with fire protection jackets are used for
applications on fire dampers in subway and tunnel systems.
The actuators are functional tested for ambient temperatures up to +250
°C for 2 Hours.
During the test the Spring Return safety function operated the dampers
to the decided emergency position and kept the damper stable.
This is the RCE-SR unit without protection jacket. It will be positioned with the actuator
vertical and mounted on dampers in subway stations.
Total quantity for this project: 710 pcs RCE-SR.
Safety at low and high ambient
RCE-SR actuators are used for indoor and outdoor applications.
3-phase motor standard: -40 °C to + 40°C (-40 °F to +104 °F)
1-phase motor standard: -20 °C to + 40 °C (- 4 °F to + 104 °F)
3-phase motor in Ex design: -20 °C to +40 °C (-4 °F to + 104 °F)
RCE-SR can be supplied for 3-phase 400V / 230V / 50HZ and
Torque range: 57 Nm to 5,620 Nm (500 lbf.in. to 49,700 lbf.in.)
Safety all over the world
RCE-SR actuators are used for safety function on valves and dampers from
Svalbard in North to Sidney in South. By an emergency
shut-down or a power failure the well proven Spring Return Safety
function operates the valve to the decided emergency position Open or
