H-Kuhnke - Model 72 Series -Mechanically Operated Micro Valves
The Series 72 micro air valve was developed as a low cost, reliable signal element for mounting in confined spaces. The valve has an air assisted servo plunger design providing a low actuation force of 100 grams.
Valves are designed to match the dimensions of standard electrical micro switches and have similar actuating forces. Mounting is via through body holes which minimise the need for brackets and allow the valve to be mounted in very tight spaces.
These valves are equipped with instant push in fittings to accommodate flexible 4mm O.D. tubing, eliminating the need for extra fittings. The exhaust port (3) is internal and non accessible.
An air assisted servo controlled pilot consumes approximately .07 litres per minute and provides an air cushion for the plunger operator. The pilot supply is internally connected to port 1 (air supply) of the valve.
