Electric internal thread ball valve, welded ball valve

overview

The Q911 electric internal thread ball valve is suitable for situations where two positions are cut off and adjusted. The connection between the valve and the actuator adopts a direct connection method. The electric actuator has a built-in servo system and does not require a separate servo amplifier. It can control the operation by inputting a 4-20mA signal and a 220VAC power supply. It has the advantages of simple connection, compact structure, small size, light weight, low resistance, stable and reliable action. The actuator can be configured with electronic electric actuators such as UNIC, PSQ, HQ, DHL, or pneumatic piston actuators such as GTX and AL according to user requirements.

The CH series actuator can directly receive 4-20mADC or 1-5VDC control signals output by computers or industrial instruments, with a 220VAC power supply. Based on the deviation between the valve position feedback signal and the set value, the actuator drive motor is intelligently step adjusted (PID adjusted) to achieve precise positioning of the valve or other device opening that matches the actuator, while outputting 4-20mADC position feedback signals. Its core control component, the electronic servo controller, is designed using modern digital technology and DCS/PLC specifications, integrating signal acquisition, processing, feedback, and control. Adopting a unique electronic braking circuit and adding a mechanical damping device to eliminate inertia, it can instantly stop the machine without oscillation during positioning, and the positioning accuracy can reach over 0.3%. Controllable silicon output, fast action time, stable output, high reliability. Small size, lightweight and pleasant, reliable performance, simple matching, high flow capacity, especially suitable for occasions where the medium is viscous, contains particles, and has fiber properties. At present, this valve is widely used in industrial control coefficients in industries such as food, environmental protection, light industry, petroleum, papermaking, chemical engineering, teaching and research equipment, and power.
