Product overview
POQ series electric actuator is used to 0~270°rotary valves and others similarity product; such as butterfly valves, ball valves, damper valves. baffle valves, plug valves and shutter valves, etc. it 380v/220v/110VAC power for the drive power supply, with 4-20mA current signal, or 0-10VDC voltage signal as a control signal, can be make the valve to move to the designed position, realize the automation control, maximum output torque up to 4000N*M (This series of product has obtained CE and explosion-proof certification, product quality has the guarantee);tee);tee);
Product Features
1. Small flow resistance. The ball valve has smaller flow resistance among all valves. The flow resistance is very small, even if the valve is reduced bore.
2. Thrust shaft bearing can reduce the fricative torque of valve shaft in order to make the shaft operation balance.
3. The seat has a good sealing performance with adopting PTFE as the sealing ring. And the sealing performance can be better with the increase of pressure.
4. The stem can only work by rotary motion, and the packing is not easy to destroy. So the steam has a reliable sealing performance
Applications
Can be widely used in petroleum, chemical, water treatment, vessel, papermaking, plant, heating, building automation, light industry and other industries; etc.
Widely used in petroleum, chemical, pharmaceutical, light industry, automatic control system
