Purchase Guide

·   Confirm the valve size you need. We offer 30Nm to 6000 Nm. Electric actuator to fit your valves.

·   Confirm the connection standard of your valves. Such as ball valve in ANSI, JIS, DIN, and UK standard.

·   Confirm the pressure and working temperature. Pressure and temperature are the important points and those may affect the cost.

·   Confirm the voltage you need. The right voltage could help your valve operate better.

·   Confirm the actuator type you need. We have on/off type, modulating type, intelligent type, explosion-proof type, IP68 type and auto return type electric valve actuator for your project.

Installation Instruction

·    Verify that the valve breakaway torque is less than the rated output torque of the actuator.

·    Any mechanical stops that would interfere with the operation of the actuator must be removed before installation of the actuator,i.e.lever,travel stops,etc.

·    The actuator output coupling must be centered with the valve stem to prevent side loading, which causes premature stem packing wear.

·    To use the manual override feature (identified on cover label), the override shaft must be pressed down firmly at least 1/4" in order to disenaage the motor from the gears. The manual override is not designed to overcome torque in excess of the rated torque of the actuator. Serious damage to the gear system may result from excessive turning force on the manual override.

·    This Series actuator may be mounted in any position, i.e.horizontal, upside down. If the conduit entrance points upward, conduit piping must be oriented as to prevent condensation from entering the actuator from the conduit pipe.
