Electric actuator
Quarter-turn modulating electric actuator
Quarter-turn modulating electric actuator can be used to control various valves with a regulating angle of 0-90° and the torque range is: 35-10000Nm. It can used for control all of quarter-turn valve like: flue cut-off gate, boiler's primary and secondary wind, boiler's side wind, air pre-heater inlet and outlet damper regulator, butterfly valve, ball valve, louver valve, damper, plug valve, flapper valve, etc. Explosion-proof Grade: IP67, IP68.
Linear-turn electric actuator
Linear-turn electric actuator is an electric actuator which outputs linear displacement and can be used to control various control valves in need of linear displacement, such as single and double-seat control valve, sleeve control valve, high temperature and high pressure water supply valve, desuperheater water and other control valve. Explosion-proof Grade : IP67.
Multi-turn electric actuator
Multi-turn electric actuator can be used for control various of valves, like gate valve, globe valve, high temperature and high pressure valve, desuperheating water valve and other rotate valves with 0-360° rotation, and the torque is 60～6000Nm. Explosion-proof Grade : IP67.
Technical specifications
Double-sealing protector
Two barriers fitted with O-ringsinsure on optimum protectionagainst water ingress into theelectronic compartment. This protection remains effectiveeven if the cover has not beenclosed properly or if the coble glandshave not been tightened. Protection is also ensured forthe local control selectors thonksto internal reed switches whichprevent moisture ingress
Mainly Features
◆ Valve Position
Limitation and Protection
Actuator automatically stops after traveling to the closing position or open position.
◆ Protection of Instant
Reverse Running
When the actuator receives a command for motion in the opposite direction, it automatically add a time lag, to prevent unnecessary wear to the valve shaft and transmission box.
◆ Power Brake
It helps to improve precision of valve position.
◆ Access-free
Debugging
Working parameter setup, system status inquiry can be realized on buttons or infrared controller, without needs to open the electrical protection cover, so that dust, moist and other hazardous substances in the environment can not enter the actuator and the reliability of electrical control will be greatly improved. ◆ Dead Zone Self-adaption In "Remote Auto Control" mode, no setting or dead adjustment will be required, and the system can, on basis of its operating status, automatically measure and locate and precisely determine the dead zone values, ensuring vibration-free and high-precision operation of the actuator.
◆ Easy Wiring
Quick-set connection is adopted on the actuator for wiring. The external wire is connected to the plug, and the actuator can be removed simply by unplugging operations. The plugs are water-proof and thus prevent errors by reconnection during maintenance process.
◆ Power-loss-safe
Status Indication
The configurable bi-stable relay output contact can be used to indicate various status of the valve (including open/close limits, over-torque, operating indication or destination position of valve, etc.), which will not change even the system loses power supply.
◆ Multiple Controls
① Field control
When the system runs in "Field Control" mode by using the "Field Control" button, the "Open", "Close" buttons or "Infrared controller" may be used on site to control the opening, closing or stopping of valve.
② Remote switch control
The switch control provides three input terminals, respectively Open, Close, Stop/Hold; Switch control can realize "Hold" or "Inch" control by external circuits.
③ Remote current control (also known as Remote Auto Control)
Users can control the actuator operation by DC4~20mA electric current, to realize precision positioning of valve.
④ Two-wire control
The actuator provides two-wire power operation functions. It can realize special controls, such as "Open on signal" and "Close on signal".
