Abstract: An open/closed indicator is positioned on the balance stem end of a high pressure gate valve and operates mechanically to expose symbols which are universally understood to state whether the valve is open or closed. The indicator is two sided and the open/closed symbols are exposed on opposite sides of the valve. In one embodiment, an indicator panel is connected directly to the balance stem of the valve. In other embodiment, an indicator panel is biased by a spring against the balance stem. In another embodiment, the indicator panel is pivoted to an extension of the balance stem. In all embodiments, the indicator panel is operatively connected to the balance stem and mimics movement of the balance stem and thus the valve gate.
