Pneumatic valve positioner series products receive the air source pressure signal from the control system and adjust it precisely according to the signal pressure，It's a device that controls valve opening.
Features：
1： Adopt earthquake-resistant reinforced structure, and the action is very stable in the field of large vibration.
2： After more than 10,000 fatigue tests and seismic tests to ensure the stability of the product 100, .
3： The response speed is fast and the positioning is accurate.
4： Split-range control 1/2 can be achieved by simply replacing parts.
5： Small gas consumption and good energy saving.
6：The z direct-reverse conversion is very simple / .
7： Zero span adjustment is very simple.
8： Feedback connections are very simple.
