UL / FM FIRE PROTECTION PRODUCTS USPVH Indicator Post are used in fire protection systems and perform several functions. The Indicator Post provides a means to operate a buried or otherwise inaccessible valve. Also, the Indicator Post readily and clearly indicates whether the valve is open or shut. All USPVH Indicator Posts are UL listed and 4-14" Indicator Posts are FM Approved. USPVH Indicator Posts are designed to withstand up to 900 ft. - lbs. of operating torque. USPVH Indicator Posts are designed to operate 4" through 24" post indicator valves requiring 14 to 75 turns to open, and can be ordered to open left or open right. They are available in adjustable, non-adjustable or wall mount styles. All have a cast boss on the upper barrel that is tapped with 1/2" NPT to allow a supervisory switch to be installed. The USPVH Adjustable Indicator Post has a 24.25" adjustment range* and can be easily adjusted in the field without disassembly. The unique telescoping stem shaft design speeds field adjustment and eliminates the need to disassemble and saw off sections of stem. The base bell is attached to the lower barrel with large diameter set screws to speed installation. The upper barrel is made of tough carbon steel, and the telescoping lower barrel is made of schedule 40 PVC material (ductile iron is optional). The USPVH design uses the operating wrench to make the post tamper proof. The operating wrench can be stored on the Indicator Post (as shown in the illustration to the right) so that one end of wrench fits over the post operating nut to secure it in position. A slot in the wrench handle fits over a post on the barrel. A customer supplied padlock can be used to lock the operating wrench to the barrel to resist unauthorized operation. The USPVH Wall Mount Indicator Post is used to operate a valve installed behind a wall and indicates if that valve is open or shut. The Post has a 12" diameter base with 3/4" bolt holes which can be mounted to a wall. *Applies to "ORDER LENGTH" codes B through F; code A has 22" adjustment.
