Shuff-off, Shear Valves and Check Valves

OPW offers a wide selection of underground storage tank equipment. This equipment is designed to help protect the environment by providing fuel operations with spill containment manholes, manholes and monitoring equipment, fill pipe connection equipment, overfill prevention equipment and tank venting equipment.

Vertical Check Valves are installed directly below the inlet in the pump in the dispenser island to maintain prime.

OPW Emergency Shear Valves are installed on fuel-supply lines beneath dispensers at grade level to minimize hazards associated with collision or fire at the dispenser. If the dispenser is pulled over or dislodged by collision, the top of the valve breaks free at the integral shear groove, activating poppets that shut off the flow of fuel.

Vapor Line Shear Valves are installed on vapor return lines beneath dispensers at grade-level to minimize hazards associated with collision or fire at the dispenser.
