OPW 60V Series Vapour Line Shear Valves

OPW 60 Series Vapor Line Shear Valves are installed on vapour return lines beneath dispensers at grade level to minimise 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 to minimize damage to the dispenser piping. Poppeted models afford additional protection by preventing the release of vapors from the dispenser’s internal piping and the vapour line to the tank.

The base of the Vapor Line Shear Valve is securely anchored to the concrete dispenser island through a stabilizer bar system within the dispenser sump or pan while the valve top is secured to the dispenser structure to ensure proper shearing action.
