Description

DCL compact quarter turn electric actuators have been used to automate butterfly valves for 19 years with over 150,000 pcs are now still working around world.They are typically used to drive quarter turn butterfly valves, ball valves, dampers and swinging arms.Butterfly valve needs large torque at full close position to push valve plate into the valve seat or pull valve plate back from valve seat, especially for soft seal butterfly valve. That’s why start torque of actuator is very important. All DCL actuators are tested and certified to start with over rated load in -10% rated voltage. So it is commonly seen that DCL-10 with 100Nm standard torque actuator can drive DN100 butterfly valve, while other brands need offer 200Nm standard torque actuator.

Actuator has been rigorous tested by CSA per UL and CSA standard. The duty rate can be over 70% for all series. The EPS system is self-calibrating which virtually eliminates "hunting" and provides an output position monitoring signal as standard.
