During installation: our staff can install pipes from any angle, but in order to make it easier for future maintenance personnel to repair, we should not install pipes upside down. Generally, this product is used in a one-way way, so when our staff installs it, the arrow on the valve body should be the direction of the medium pressure of the sealing parts. 　　

Fault 8: The actuator vibrates and beeps. Treatment method: mainly because the sensitivity is adjusted too high, the insensitive area is too small and too sensitive, which causes the small circuit of the actuator to be unstable and produce oscillation. Adjust the sensitivity potentiometer counterclockwise to reduce the sensitivity; The fluid pressure changes too much, and the actuator thrust is insufficient; If the control valve is selected too large, the valve often works at a small opening.
