Multi-turn electric actuators for intelligent integration. Valve to achieve open, close or adjust the control-driven equipment. Applies to gate, globe valves, diaphragm valves, plunger valves, throttle valves, water gates, etc.. For the next shot valve, rising stem valve can also be used.
This series of actuators functional, reliable performance, and advanced control systems, small size, light weight and easy maintenance, and other characteristics. Remote control, centralized control and automatic control valves to implement.
The performance of this product comply with the provisions of the the JB/T8528-1997 valve electric device technology, ". Flameproof performance in line with GB3836.1-2000 "explosive gas atmospheres - electrical equipment - Part 1: General Requirements, and GB3836.2-2000" explosive gas atmospheres - electrical equipment - Part 2: Flameproof "d" " the JB/T8529-1997 flameproof electric valve device technology, "provisions.
Feature
A Chinese display: the integration of multi-turn electric actuators window with high-definition LCD digital, all Chinese and identifiers LCD screen.
(2) the phase sequence automatically corrects: The executive body of rotation can be set freely, but also the freedom of correction power supply phase sequence.
3 phase protection: power to lack of protection.
Control modes: the conventional remote control signal DC24V fully open, fully closed control / 4-20mA analog signal control, 4-20mA signal is fed back (special control). The remote control signal, the feedback signal and the internal electrical isolation.
Ban move to delay protection: to avoid or reduce the mechanical parts of the reaction force due to inertia bear. This protection also applies to the field control mode and the remote control control.
Electronic interlocking protection: an instruction is executed and then impose another reverse control instruction (ie two order also exists and is valid), the electric actuator will stop running up the first instruction and then the next instruction
Instant over torque protection: on or off instantly to torque the top open, the valve will stop does not act, even if the torque switch instantly open the top closed, the valve is still not action, and only look to the reverse action, ie can be lifted over torque protection.
8 scene remote control switch: the scene remote control free to switch, allowing users to debug, maintain convenient.
