Electro Pneumatic Positioner YT-1000

Electricity-Gas valve locator YT——1000 seriesproduct is a device that is used to regulate the valve opening precisely by reception of 4~20MA direct current signal from the control system.

Features

1. The high shock resistance; the motion is very stable at the field with high shock.
2. After the motion test and shock resistance tests of 1,00,00 times above,it ensure the product stability.
3. The reaction is quick, and precision is high.
4. By the simple adjustment can realize the 1/2 range travel control.
5. The air consumption is little,and energy saving performance is good.
6. Positive/opposite effect can be convenient to transform.
7. Zero point, range adjustment is very easy.
8. It is very easy to feedback connection.
