While working with water utilities, there are some valves that you may want to know the position about as for fire suppression, frequently exercised valves, or those which require a very fast response to an emergency. One option which you can consider is adding a Fire Indicator Post or Post Indicator Valve or PIV to that part of your system. But what is it, how does it work and where should you add it? Here is a quick overview of them.

These heavy-duty valves are used with automatic sprinkler and wet standpipe systems and are available to work with gate valves between 3" and 24". 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 which includes an indicator for showing whether the valve is currently in an open or closed position. The handle is located traditionally on top of the post and is locked in either the closed or open position when not in use, which creates a slim profile for preventing anything from catching on it accidentally. When the gate valve is lowered completely for opening the valve, the indicator is lowered for reading that valve is open which makes it easily apparent to anyone nearby that valve is in operation. The valve is later, raised to close the connection which raises the indicator which shows that the valve has been closed that allows the fire department or water utility personnel to quickly verifying that it has been closed completely. The locking position of the handle also ensures that the valve will have been wither completely opened or closed rather than being left open partially. Fire indicator posts mainly include some kind of adjustment so that it can be used for retrofitting an existing valve is you have a paving or construction project which is expected to impede access to your existing gate valves. Again to a wide range of gate valves they can also be adjusted from several manufacturers which provides that the valve adjustment head and the PIV's wrench end match, as the indicator blank can be adjusted down or up into the correct position for the particular combination. This can be accomplished in the field without trouble which allows your crew for implementing this type of system. Beyond fire suppression systems, you can also include PIVs in areas where you have had breaks or frequent maintenance in the past which allows your crew to tell at a glance whether the valve is closed or open so that it can quickly move it into the position they need without any guesswork. By incorporating Post Indicator Valves into your critical infrastructure systems and fire suppression, you can be assured that at glance, the position of the valve is known instantly.
