Electric butterfly valve (the valve plate) around the vertical channel of the fixed axis of rotation of the valve by the electronic transition back to the rotary electric actuators and butterfly valves, is a rotating high-performance adjustment or switch valves accept industrial automation control instrument the source of the current signal or voltage signal input ratio adjustment or two switch control of the fluid medium in the process piping, flow, pressure, temperature, level and other parameters to achieve the fluid medium automation and control. Widely used in gas, liquid, turbid liquid, concentrated slurry or ash, suspended particles and other media.
Features
A. Electric butterfly valve operating torque, is one of the smallest of all valve operating torque, the execution unit of the automated control system instrumentation, AC220V, AC380V or DC24V power supply voltage for power, acceptance (DCS, PLC) system or adjust the instrument, the operator inputs (4-20mA, 0-10mA or 1-5VDC) current signal or voltage signal to control operation. Rotation output torque of the rotary valve shaft 0-90 º will be able to complete the opening and closing movement or adjust the action. Fully electronic electric actuators, using mechatronic structure, inside the servo operation and opening signal position feedback, position indicator, manual operation, functional, reliable performance, the connection is simple, precise control, small size, weight light, small flow resistance, flow coefficient, simple structure, good sealing performance. Adjustment range, the input current signal or voltage signal, this shift into the displacement corresponding to the input signal, changing the angle of rotation of the valve plate (0-90 º at any angle), and a certain input signal corresponds to a certain corner, to achieve proportional action, therefore, better regulation and control flow and other parameters.
Two. HL type 3810R type, PSQ type rotary electric actuator for fully electronic drive unit of the O type ball valve, mechanical and electrical integration of structural design, position feedback of the machine servo operation and opening signal, position indicator, manual operation functions, functional, reliable performance, simple connection, as the power supply voltage AC220V or AC380V to accept a unified standard signal (4-20mA DC ,0-10mA DC or 1-5V DC, 0-10V DC), into the displacement corresponding to the input signal to change the rotation of the ball core opening displacement (0-90 º) movement to the point of view, the input signal corresponds to the opening of a certain position to achieve proportional control action. (Two switch-to AC220V or AC380V supply voltage for power, motor reversing switch action, and at the same time the output of the switch valve position indication signal). Is a high precision, high-performance, high reliability products.

(A). Block flexible sealing structure
Block flexible seal structure, with eccentric disc installed in the valve stem on its side results for spherical, conical two, and compatible with the elastic ring seals made of L-shaped and U-shaped two disc sealing face coincide. Medium pressure seal pair, resulting in a tiny elastic deformation, in order to achieve sealing. Valve nominal diameter, nominal pressure to choose the form of its structure, according to the pressure by the force design of ring wall thickness.

(B). Multi-level seal structure
Multi-level seal structure, the use of hard and soft stacked metal ring, the multi-laminated ring fixed butterfly board, it does not bend and move, and effectively avoid the direct erosion of the medium on the laminated ring, the valve seat sealing surface with excellent wear resistance of cemented carbide electrode surfacing, thereby increasing the life of the butterfly valve. And has the dual advantages of the metal seal and elastomeric seals, both in the case of high or low temperatures, with excellent sealing performance. Three-dimensional partial core structural design, seat and disc are almost without friction, with more to shut more tightly sealed.

(C). In the linear structure
Linear structure, the body, the lining layer (PTFE or rubber) and (stainless steel valve plate, or chrome steel valve plate), composed of the valve shaft, the media that the streamlined design of the structure similar to a straight line, good regulating performance. sealing structure for the Habitat Centre linear sealing, sealing performance and reliable way to achieve zero leakage seal can be installed anywhere.
