Actuator Cover Strong anti-corrosion capability due to anodic oxida-tion treatment inside and outside.Made of advanced Aluminum Alloy, GEQ quarter-turn electric actuators are small, light but durable which ensures long ser-vice life. Since both inside and outside of the actuators are treated by strong anodic oxidation treatment, they are fea-tured by strong anti-corrosion capability. The anti-corrosive O type seal system is waterproof and explosion-proof. To pro-long the service life, there are damp proof heater and thermo-electric protection devices in the actuators.
Based on conventional reliable mechanical transmission, GEQ
quarter-turn electric actuators control the quarter-turn valves
such as ball valves, butterfly valves and dampers through
partial rotation.
With excellent performance and superior function, GEQ quar-
ter-turn electric actuators are artistic in appearance, light and
easy to debug and operate. They can satisfy the requirements
for the controller on both frequent debugging and intermittent
control.Summary

Characteristics:
Terminal blocks:
G 22pcs blocks is enough and convenient
for the customers to operate
G Ensure fastening, tight wiring and
reliability Blow out protection bolts G The special designed bolts on the top cover will not fall during assembly and maintenance G All external bolts are made of stainless
steel material and will not rust
Space heater
G 7~10W, Ceramic layer, at the same time
function as the constant temperature
regulator adjusting temperature, to prevent
overheating. It will automatically shut off
when the temperature is over 65
G No risk of leakage current Torque switch G The valve will lock when impurities flow into the body and the torque switch will automatically cut off power supply in case of over torque.G Protect electronic and mechanical components
