ABSTRACT:
A check valve of the type having a counterweight is provided wherein the counterweight is mounted on a shaft directly above the shaft carrying the valve disc, the counterweight being connected to the shaft carrying the valve disc by gearing. By mounting the counterweight above the valve disc, the valve does not require any additional width for installation and is thus adapted for installation in tight quarters.
