The LNA-1015PDL is an ultra-precise Linearity actuator that enables the implementation of a fixed degree system due to the optimal combination design of the driver and valve, developed exclusively for each other, so that no distortion or hunting of control characteristics occurs. In this product, the vulnerability of the ball valve, the neck leak generation problem The valve shaft part was sealed and disclosed in 3 parts, thereby enhancing durability and greatly reducing the possibility of leaking. In addition, by blocking the fluid to the leak from shattering to the outside and outputting an alarm by the LEAK DETECT function that is built in at the same time, a rapid response before the occurrence of lssue is possible. The actuator has the characteristics of feedback standard mounting/6 control signals selectable, resolution 1200:1, compact design domestic minimum, connector detachable, and the valve is made of a strong corrosion resistance scs14A material, and can be applied to a variety of Orifice.
