YT1000L
The YL-1000L electric valve positioner is a device that controls valve opening by sending a 4-20mA DC electrical signal from a controller or control system and supplying air to a linear pneumatic actuator.
No resonance phenomenon within the range of 5-200Hz;
Forward and reverse, easy conversion between single acting and double acting;
For small actuators, vibration can be prevented by reducing the throttle hole of the locator;
Low air consumption and good economy;
It is possible to achieve split range control within 1/2 range without replacing parts.
