Emergency Shut-off Valve Installation – Orientation
Emergency Shut-off Valves are designed for installation in liquid or vapor transfer lines at LP-Gas or Anhydrous Ammonia bulk plants to provide for quick shut-off of liquid or vapor flow in the event of an accidental pull-away, line break, or hose rupture.
When installing an Emergency Shut-off valve it must be installed to shut off the flow from the tank towards the hose, enabling the valve to control product loss in case of a hose break. These valves are spring closed (aided by pressure) and shut off the flow in one direction only. Flow direction is indicated by an arrow on the body. The arrow shall point to the hose connection away from the container. Regardless of the product flow, the valve must be installed with the arrow pointing away from the storage tank. Improper flow direction will not shut off the flow through the line.
Emergency Shut-off Valves can be installed in vertical and horizontal piping. When installing in a vertical position, actuators must be installed with a means to protect from the weather. A protective cover must be installed to prevent freezing of the actuator Assembly in cold conditions.
