Valve-Cyl Filling 1/2 Automatic

FISHER Type N201 automatic cylinder filling valve provides an accurate and economical means of filling cylinders. The assembly comes completely piped up and includes special parts that allow the slide weight on the scale to move to zero. A red button appears in the indicator on top of the Type N201 each time a cylinder is filled to the desired weight. Operated by air pressure, it is designed for beam type scales and requires no electrical or mechanical power.
