Seismic Three-Way Valve

Model 400 Seismic Three-Way Valve is designed to actuate during strong earthquake shaking. When you receive the Model 400, it will be in its actuated position. When the Model 400 is actuated, a red bar is visible through the window in the position indicator located on top of the valve just above the clamp band.
Model 400 must be manually reset. Using a screwdriver or wrench, apply light force to rotate the reset shaft counterclockwise until the green bar is visible through the window. Release pressure on the screwdriver or wrench, and the reset shaft will return to its original position. The green bar will remain visible through the window. Model 400 Seismic Three-Way Valve will now be in its normal operating position, and the acceleration trigger mechanism will be set to respond to seismic disturbances.
