Abstract
A pressure responsive check valve designed to quickly close in response to a drop in pressure below a pre-determined level. When used at the top of a fluid filled tank such as one used for heating oil, the valve prevents tank syphon by stopping fluid flow at the tank in the case of breakage of supply or return lines, The valve is contained in a pre-assembled unit for ease of installation.
