Description

This is a single valve seat regulator valve with a diaphragm driver using air pressure operation. The stroke of the stem varies depending on the supplied air pressure, and flow can be varied by altering the gap between the stem and body. A stellite is used on both the valve element and valve seat, making it highly heat, corrosion and wear resistant, suppressing erosion and corrosion to give a longer lifespan. It is used in tier curing presses to control the shaping pressure with steam and to control the temperature of the platen and container jacket.
