Available to work with gate valves between 3” and 24”, these heavy-duty valves are used with automatic sprinkler and wet standpipe systems. When the system main valve is located under pavement or concrete, it can be difficult to tell whether the valve is open or closed at any given point. A post indicator system includes a means of exercising the valve above pavement that includes an indicator to show whether the valve is currently in an open or closed position. The handle is typically located on top of the post and is locked in either the open or closed position when not in use, creating a slim profile to prevent anything from catching on it accidentally.
When the gate valve is fully lowered to open the valve, the indicator is lowered to read that the valve is open, making it easily apparent to anyone nearby that the valve is in operation. Later, the valve is raised to close the connection, raising the indicator that shows that the valve has been closed, allowing fire department or water utility personnel to quickly verify that it has been completely closed. The locking position of the handle ensures that the valve will have been either completely opened or closed rather than being left partially open.
Indicator posts typically include some form of adjustment, so they can be used to retrofit an existing valve if you have a paving or construction project that is expected to impede access to your existing gate valves. They can also be adjusted to a wide range of gate valves from different manufacturers, providing that the valve adjustment head and the PIV's wrench end match, as the indicator blank can be adjusted up or down into the correct position for that particular combination. This can be accomplished in the field without too much trouble, allowing your crew to implement this type of system.
These valves can also be included in areas beyond fire suppression systems where you’ve had frequent maintenance or breaks in the past, allowing your crew to tell at a glance whether the valve is open or closed so that they can quickly move it into the position they need without any guesswork.
