Multi-turn electric actuator has good sealing performance
The electric gate valve is composed of an electric actuator and a gate valve body. The power supply pressure is used to control the gate plate to move up and down in a straight line to connect or close the fluid medium in the pipeline.
Overview
The electric actuator adopts a composite structure in structural design, and more thoughtful considerations are made in the generalization, standardization, and serialization of parts, so that the product is composed of machinery, motors, and control circuits into a variety of different series and specifications. Users can The number of spare parts required for use and maintenance is greatly reduced. The base of the product reducer is made of high-strength aluminum alloy. The mechanical structure design is simple and compact, with high reliability, small size and light weight; multiple connectors can be installed in any position and in any direction.
Electric actuator types
Specifications and features
1. Voltage of the power supply: 380V50HZ Controlling voltage: 220 V50HZ
2. Input controlling signal: 4~20 mA DC Ri=250Ω
3. Output valve position signal: 4~20 mA DC RLmax=300Ω
4. The actuator and controlling box are assembled separately in order to adapt the effect of the over-high environment temperature.
5. Requirement of control mode: automatically modulate to stop at the terminal 34° and alarm. If it is necessary to modulate for the ending position, it can be startup forcefully to the ending position to guarantee the security of the equipment.
6. environment temperature:10~55 degree centigrade
7.Humidity: ≤85% no corrosive characteristic exist in the ambient air
8. Protection class: IP65 IP67
Internal details
Human-machine interface liquid crystal display. FRYSD series electric actuator adopts LCD liquidcrystal display with backlight, which displays thevalve position, torque and functional status of the actuator in Chinese or English, numbers, graphics, etc,and is displayed by LED indicators The fully open andfully closed positions of the valve still have strongpenetrability even in harsh environments, allowingusers to see the status of the actuator at a glance.
On-site operation unit. The on-site magnetic rotaryswitch can switch between on-site and remote control states when completely isolated from the electrical box, and easily control and set the actuator.
Overtorque protection function. Actuator is equippedwith a torque protection measurement, the role of thetorque can be accurately measured valve, when morethan set range, located within a actuator torque switchsends out the signal to the control circuit, the circuithas a memory function, will lock actuator running inthe direction of the output signal, motor stalling, so asto protect the valve and actuator drive and motor.When the mechanical torque failure is eliminated, theactuator is switched off or the signal is reversed in aninstant to return to normal work.
Using reasonable integrated compression technology, the powerfulsystem integration function is fully reflected in the wide range of productfunctions, and fewer electronic components and complex electronic connections are used to ensure that the electric actuator has a high degree ofelectronic control reliability.
