Product Description
More Information
The Soval 813 Series ULFM Indicator Post is designed to operate non-rising stem gate valves used in the control of underground water supply for automatic sprinklers, water spray deluge, foam-water deluge, and standpipe fire protection systems. It allows for the operation of underground valves while providing an above ground visual indication as to whether or not the valves are open or shut. With this indicator post, valves can be locked into a particular position and operated from outside of the protected property, which makes prompt valve operations possible in case of emergency.
The Indicator Post features a telescopic stem that can be adjusted to its final position without field cutting the stem. It permits 1) easier setting of the OPEN and SHUT target plates (before the post is extended to its final position); 2) easier adjustment of the post length during the initial installation; and 3) ready re-adjustment of the post length if the position of the final grade has been modified.
Our Indicator Post will accommodate 4”–12” post indicator valves (PIV) requiring 14 to 43 turns to open that are listed or approved for fire protection system services. It is manufactured for use with left-hand opening valves by default but can be special ordered for right-hand opening valves or converted in the field for such use by changing the left-hand opening post head to a right-hand opening post head. This indicator post is designed to withstand up to 900 ft. lbs. of operating torque.
The Indicator Post accepts direct attachment of a 1/2” NPT mounting electric supervisory switching device which can be used by proprietary and central stations to monitor the open position of the indicator post. Detailed information on attaching a UL/FM approved supervisory control valve switch (supplied by customer) is given in the technical data section.
