Electric three-piece ball valve works
Electric three-piece ball valve (female threaded ball valve) and the ball valve is divided into the overall welding (one type), two-and three-stage type. Body casting using imported advanced technology in Taiwan, a reasonable structure, handsome in appearance. Seat with flexible sealing structure, reliable sealing, easy opening and closing. Stem with inverted seal down the structure, the valve chamber abnormal pressure, the stem will not be washed out. Two-piece, three-piece ball valve connections are available with butt fusion (BW) socket welding (SW) and are available with international standard ISO bracket platforms and locking devices. Can be set to 90 ° switch positioning mechanism, according to the need to lock to prevent misuse, drive mode: manual, electric, pneumatic. 1. Three-piece electric ball valve fluid resistance is small, all valves in the fluid resistance of a minimum, with AC220V, AC380V or DC24V power supply voltage as a motivation to accept (4-20mA, 0-10mA or 1-5VDC) current signal or voltage Signal, you can control the operation of the torque output torque to the sphere of rotation 0 ~ 90 °, you can complete the opening and closing action or adjustment action. 2. Fully electronic electric actuator, adopt the structure of mechatronics, with the function of position servo and position signal feedback, position indication and manual operation in the machine. It has the advantages of strong function, reliable performance and simple connection. By input current signal or voltage Signal, change the rotation angle of the core (0-90 ° any angle), to achieve proportional adjustment action. 3. Ball core channel smooth, difficult to deposit medium, can be pipelined ball. Simple structure, light weight, good sealing performance. Particularly suitable for applications requiring zero leakage rate.
